Send us Fan MailPeaches goes solo to finish another stack of Operator Training Summit questions — or at least tries to before the ribs downstairs start calling his name.This is OTS FAQ Part 2, and it starts with one of the biggest questions candidates ask: what actually gets people through the hardest parts of selection and the job?Peaches' answer is pretty simple. Train your ass off. Build confidence through preparation. Get comfortable spending a lot of time on your feet. Run. Swim. Ruck. Be durable. And understand that the physical version of you that gets through selection may not be the version of you that your operational team eventually needs.Then he gets into what actually makes a good teammate: integrity, reliability, communication, stress tolerance, teamwork, trainability, fitness, and drive. The inverse is just as important. If people cannot trust you, cannot rely on you, or have to constantly motivate you to do your job, you become a liability fast.The episode also hits peer reviews, breath-hold apps, the four stupid mistakes candidates keep making, why dangerous jobs are still worth doing, and an easy way to build push-up volume without pretending every workout needs to be some heroic event.Then things widen out: drone warfare, one-way attack drones, counter-UAS, and why the next fight will probably look very different from Iraq or Afghanistan.Peaches also gives his mental-toughness trick: get on a treadmill, shut off every distraction, remove the clock, and live inside the suck. If you say you are running six miles, run six miles. Stop when the job is finished, not when it becomes uncomfortable.He also breaks down Whoop recovery scores, why yellow does not mean “take the day off,” how people sabotage themselves by redlining every workout, and why backing off to 70–80% can actually produce more useful weekly training volume.Then there is pipeline-specific stuff: possible two-week prep between BMT and SWAS, when spouses may join you, BAH questions, how fast a “good runner” should actually be, why Rocket Fins destroy your feet, what gear you can bring, and one of the most important lessons Peaches learned at Combat Dive School:Eat. Everything.You are not there to get shredded. You are there to pass.

HRV, vagal nerve training, and nervous system recovery are having a real moment — but most people using a wearable to track any of it don't actually know what the data means or how to act on it. Matt Bennett, founder of Optimal HRV and a former mental health therapist specializing in complex trauma, joins Freddie to explain what heart rate variability is really measuring, how resonance frequency breathing trains the vagal nerve directly, and why a validated baseline matters more than any single readiness score.They get into RMSSD vs. SDNN vs. high frequency HRV, the science behind resonance frequency breathing, and how vagal nerve training works like a strength practice — the more you do it, the more resilient your nervous system recovery becomes. Freddie and Matt also cover the everyday levers that move HRV most: alcohol, sleep consistency, fasting windows, walking, and nasal breathing. Matt closes out with how clinicians, coaches, and military performance teams use HRV data differently than the average wearable user, and why he built Optimal HRV to make vagal nerve training and nervous system recovery accessible at every price point.Podcast Highlights:0:00 – Welcome Matt Bennett & Freddie's Optimal HRV experience2:01 – Matt's path into wellness: mental health therapy & complex trauma4:04 – The missing piece: quantifying nervous system healing6:23 – Partnering with a Harvard HRV researcher on resonance frequency breathing6:46 – HRV 101: what heart rate variability actually measures9:53 – Why the autonomic nervous system runs the whole show10:03 – Is low HRV always bad?

Connected fitness isn't replacing boutique fitness, but it is changing what clients expect from their studios. In this episode of The Business of Boutique Fitness, Studio Grow founder Lise Kuecker and Heather Garrick explore what boutique fitness studio owners can learn from brands like Peloton, Tonal, and Mirror, and how connected fitness, wearable technology, AI, and personalized training are reshaping the future of the fitness industry. They break down why community and in-person motivation still matter, how Peloton built loyalty through instructors and digital community, what Tonal gets right about personalization, and what the rise and fall of Mirror can teach studio owners about content, talent, and long-term customer value. You'll also hear practical ways studios can use wearable data from platforms like WHOOP, Apple Watch, Garmin, and Myzone to create more personalized member experiences, improve retention, and even build new revenue streams. Plus, Lise and Heather look ahead at hybrid memberships, AI-powered programming, connected health data, longevity, and the growing overlap between boutique fitness and preventative healthcare. Connected fitness isn't an either/or decision. Your clients can train at home, track their health through wearables, and still deeply value the coaching, accountability, community, and human connection they find inside your studio. The opportunity for studio owners is learning how to make those experiences work together. If you own or operate a boutique fitness studio, this episode will help you understand where connected fitness is headed, and how to use technology to create a better client experience without losing what makes boutique fitness valuable in the first place. Catch you there.

In this episode, Esty Zilberman & Mourad Bahrouch explore the science of stress, recovery, the nervous system, neuroscience, and human performance with Esty, founder of Build It Real. We discuss how the brain interprets reality, why stress itself isn't inherently good or bad, and how homeostasis helps explain the body's drive toward balance and safety.We also dive into WHOOP, wearable data, HRV, sleep, recovery, and self-awareness—and why you shouldn't let a recovery score dictate how you feel. Instead, learn how to use data as information while staying connected to your own body.The conversation also explores how these principles apply to training, exercise, leadership, management, and the workplace. From gradually increasing physical or mental challenges to understanding an employee's individual stress threshold, we discuss how leaders can create environments where people are challenged without becoming overwhelmed.Topics covered:Stress and nervous system regulationHomeostasis and the brain's response to stressWHOOP, HRV, recovery and wearable technologySleep, exercise and physical resilienceHow to build tolerance to stress graduallyFinding exercise you actually enjoyNeuroscience and self-awarenessStress management in the workplaceLeadership, employees and psychological safetyHow managers can recognize when people are under- or over-challengedIf you're interested in neuroscience, stress management, nervous system regulation, recovery, fitness, leadership, workplace performance, or understanding yourself better, this episode is for you.__https://www.builditreal.ai/

In this episode Andrea Samadi explains the concept of sleep stress — a wearable-device measured how physiologically activated your body remains during sleep — and places it within a neuroscience-based movement and recovery framework. She reviews the autonomic nervous system (sympathetic vs. parasympathetic), how WHOOP estimates sleep stress from heart rate and HRV, and why trends over weeks matter more than single nights. Using her six-month data, Andrea shares how recovery habits and removing alcohol coincided with an 89% drop in nightly high sleep stress. The episode ends with practical steps and a seven-day experiment to help you observe and reduce nighttime physiological activation by changing daytime behaviors, sleep environment, and training timing so your body can better recover and adapt. When Sleep Isn't Rest—What “Sleep Stress” Reveals About Recovery: The Story Behind My 89% Drop in Sleep Stress Welcome back to the Neuroscience Meets Social and Emotional Learning Podcast, where we bridge neuroscience, social and emotional learning, and human performance so we can create measurable improvements in our well-being, achievement, leadership, productivity and results. I'm Andrea Samadi, and if you've been following along through Season 16, you'll know that we have been building what I call The Brain's Operating System for Human Performance—a neuroscience-based framework designed to help us understand how the different systems of the brain and body work together to influence how we learn, adapt, connect, lead and ultimately perform. We are currently in Phase 3: Movement, Learning and Cognition, where we have been following a central pathway: Movement → Adaptation → Performance Movement creates a stimulus. But movement alone does not make the brain or body stronger. We must be able to recover from that stimulus before adaptation can occur, to give us our desired outcome of improved performance. This is why our recent bonus episodes have moved beyond exercise itself and into the recovery signals that help us understand whether our bodies are successfully handling the demands we are placing upon them. In Bonus Episode 3[i], we explored the hidden story behind my resting heart rate. My data showed that it was not merely a measure of fitness—it was also reflecting the total load my body was carrying. During the higher-stress months of January and February, my resting heart rate remained elevated at approximately 56–58 beats per minute. As I placed greater emphasis on sleep, hydration, Zone 2 movement, sauna, meditation and recovery, it gradually fell to 54 and then 53 beats per minute. The lesson was that a lower resting heart rate signals that the body is working less during rest, and recovering more efficiently. The idea is to learn what your baseline is, and see how you can improve this number for a more efficient RHR. In Bonus Episode 4[ii], we explored restorative sleep and learned that sleep quality is not measured by duration alone. Deep sleep supports physical restoration and repair, while REM sleep plays an important role in memory, learning and emotional processing. Because longer REM periods tend to occur later in the night/morning time my regular 4:00 AM wake time may give me less opportunity for that REM-rich portion of sleep—which is the tradeoff I'm choosing--since waking early allows me to exercise. Two additional hours in bed would not guarantee two more hours of REM, but they could create a greater opportunity for more REM sleep. The lesson was not to choose sleep over movement or movement over sleep. It was to protect enough sleep while still making room for movement, so the brain and body have the opportunity to adapt. Throughout these bonus episodes, I'm sharing patterns from my WHOOP wearable device[iii] data—not because everyone's numbers should look like mine, but to demonstrate what can happen when we measure consistently, look for trends and test small changes. The goal is not comparison. It is to help each of us better understand our own baseline and use that information to improve our habits, recovery and results. While examining my own sleep data for these recent bonus episodes, another question came to my mind. It was while looking this sleep stress score. What if we are sleeping—but our physiology remains unusually activated throughout the night? How would we even know if this was happening? This is another measurement I can see with this wearable device. What if our eyes are closed and we are technically asleep, but the body is still working harder than usual? What if our sleep isn't giving us the rest and recovery that we need. This brings us to today's question: What is Sleep Stress? One of the most valuable metrics I have been tracking this year is not simply how long I sleep or how much deep and REM sleep I achieve. Those are all important to me, but something stood out with these sleep scores to me, this year. It is the amount of time my body spends in a state of elevated physiological stress while I am asleep. When I examined my most recent six-month trend, I noticed something that kind of stopped me in my tracks. My average time in WHOOP's high sleep-stress zone (monthly score from January 2026 till now) initially rose from 21 minutes to a peak of 35 minutes (around April/May) where I noticed my sleep scores were terrible with International travel, but I can't blame everything on just the travel and times zones. I knew I was off track with rest and recovery. How much I was off, I'm not sure because Whoop confirmed my scores with the times zones might have been inaccurate, but either way, even if my sleep stress peaked at let's say 25 minutes, it still showed me that I was doing something to keep my body stressed out while I was sleeping. As I paid attention to rest and recovery, the scores began to improve in May, June, July, August…until now. 35 minutes of high sleep stress went…to 18…to 14…to 5…and finally to just 4 minutes of sleep stress each night. That is an approximately 89% decrease from my six-month peak. The data cannot tell me that one specific behavior caused this change. But it does suggest that my body has become progressively less physiologically activated while I was asleep. And this helped me see recovery in a new way. Sleep duration tells us how long we slept. Sleep stages estimate the type of sleep we experienced throughout the night. Sleep stress gives us another window into how physiologically activated the body remained during that sleep. In today's BONUS EP 5 we will explore: What Sleep Stress measures The sympathetic and parasympathetic branches of the nervous system Where Sleep Stress fits into the Movement Loop What I noticed in my six-month results What the results show—and what they cannot prove How you can monitor nighttime physiological stress And practical tips to help your body settle and recover Let's begin with the nervous system and what's working behind the scenes while we are asleep. The Autonomic Nervous System To understand Sleep Stress, we first need to understand the autonomic nervous system and how ACTIVATION and RECOVERY work together. We covered this topic on a very early EP 59[iv] with Suzanne Gundersen on “Putting the Polyvagal Theory into Practice” and then again with educational neuroscientist Dr. Lori Desautels and Michael McKnight[v]. You can review those episodes if you want a deeper dive here. The autonomic NS is the part of the nervous system that regulates many of the functions that happen automatically, without requiring conscious thought. It helps manage: Heart rate Blood pressure Breathing Digestion Temperature regulation Energy use And our physiological responses to changing demands in our life experiences Two of its primary branches are the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system helps mobilize the brain and body when we need energy, alertness or action. It is often called the fight-or-flight system. We need this sympathetic activation to wake up, exercise, concentrate, solve problems, respond to challenges and perform under pressure. When sympathetic activity rises, heart rate may increase, breathing may become faster and energy becomes more readily available for action. That is exactly what we want when climbing a mountain, completing an intense workout, delivering a presentation or responding to an immediate challenge. The problem is not activation itself. The problem may arise when the body has difficulty shifting out of that activated state after the challenge has passed. The parasympathetic nervous system supports the restorative side of this process. It is often described as the rest-and-digest system because it helps the body conserve energy, digest food and create conditions that support rest and recovery. When our parasympathetic NS is activated, heart rate generally slows and the body becomes less physiologically activated. But the sympathetic and parasympathetic systems are not simple on-and-off switches. They continually interact throughout the day and night. Healthy regulation depends on our ability to move flexibly between activation and recovery as our life circumstances change. I'm sure you've heard people talking about how they “regulate” themselves, or take themselves from a high stress state, to lower stress state usually through intentional breathing, (I've just started to add this technique), physical movement (my go-to way to get back to myself when I have time) and some people use sensory grounding to get themselves out of anxious loops. American neuroscientist Dr. Andrew Huberman suggests the physiological sigh as a breathing technique “to reduce stress and anxiety in real-time, while they are still engaging in life.”[vi] He does say that this pattern of breathing is something that we all engage in when we are in deep sleep (our dogs do it too), a double inhale, followed by an extended exhale. He says it works well to reduce stress because “it offloads a lot of carbon dioxide all at once.” Until I started to look at this sleep stress number, I didn't realize that even during healthy sleep, our autonomic activity fluctuates. Deep sleep is generally associated with greater parasympathetic influence, while REM sleep can include more variable heart rate, breathing and sympathetic activity. This means that brief periods of increased physiological stress during sleep are not automatically signs that something is wrong. The more useful question is: Can my body move flexibly between activation and recovery—or is it remaining unusually activated for extended periods? What Does WHOOP Mean by Sleep Stress? WHOOP estimates physiological stress using signals that include heart rate and heart-rate variability, or HRV, compared with your personal baseline. Its Sleep Stress view shows the proportion of the night spent in low, medium and high physiological stress zones. This is an important distinction: A wearable does not directly measure your thoughts or emotions. It cannot know whether you are worried, excited, digesting a late meal, fighting an infection or recovering from a difficult workout. It also does not directly measure the sympathetic and parasympathetic branches of the nervous system. Instead, it uses cardiovascular signals to estimate how physiologically activated your body appears relative to what is normal for you. Elevated nighttime stress can potentially be influenced by: Mental or emotional strain Alcohol Illness or an emerging infection A late or heavy meal Intense exercise close to bedtime Accumulated training strain Dehydration Heat or an uncomfortable sleep environment Travel and disrupted routines Hormonal changes Certain medications Or sleep-disordered breathing Sleep Stress should therefore be treated as a signal to investigate, not a diagnosis. One elevated night may not mean very much. The greatest value comes from observing your own patterns across several weeks and comparing those patterns with your behaviors, environment, training and health. Where Sleep Stress Fits in the Movement Loop Our original Phase 3 framework was: Movement → Adaptation → Performance But we can now expand this pathway: Movement → Physiological Load → Recovery → Adaptation → Performance Movement provides a challenge to the brain and body. That challenge creates physiological load. Recovery gives the body an opportunity to respond to the load, repair what was challenged and build additional capacity. That process is adaptation. And the capacity created through adaptation supports future performance. Sleep Stress sits within the recovery stage of this loop. It helps us investigate whether the body is successfully downshifting from the demands of the day or remaining more activated than usual during the recovery window. This does not mean that every increase in nighttime stress prevents adaptation. The body is dynamic. Exercise, digestion, illness, temperature and different stages of sleep can all affect nighttime physiology. But if elevated Sleep Stress becomes a repeated pattern, it may indicate that the body is carrying more load than it is currently absorbing. This is why Sleep Stress belongs in Phase 3: Movement supplies the challenge. Recovery determines how effectively we absorb it. Adaptation builds capacity. And capacity supports performance. What My Six-Month Results Show When I examined my 6-month Sleep Stress results from March 17 through September 12 when I was writing this episode, I first looked at six consecutive monthly windows: March 17–April 15: 21 minutes of average high Sleep Stress April 16–May 15: 35 minutes May 16–June 14: 18 minutes June 15–July 14: 14 minutes July 15–August 13: 5 minutes August 14–September 12: 4 minutes The pattern was not a straight decline. My average high Sleep Stress initially increased from 21 to 35 minutes. That April-to-May period (with International Travel) was the highest point in the six-month window—a 67% increase from the preceding month. The nightly graphs also show more frequent and more substantial periods in WHOOP's high-stress zone during that time. The data cannot tell me exactly what caused the increase. It may have reflected accumulated emotional stress, training load, disrupted routines, sleep timing, travel, temperature, or several factors interacting at once. But after that 35-minute peak, the direction changed: 35 → 18 → 14 → 5 → 4 minutes That is an approximately 89% reduction from the peak. This was not the result of one isolated night or a single unusually good week. It was a progressive decline across four consecutive monthly windows. When I switched to WHOOP's full six-month view, however, I initially noticed what appeared to be a contradiction. My six-month average was 16 minutes in the high-stress zone—60% higher than my preceding six-month average of 10 minutes. How could my current Sleep Stress be improving so dramatically while the six-month comparison still showed an increase? The answer is that a six-month average is a lagging measure. You can see my 6 month data in the show notes. This graph includes the elevated spring period, particularly the April-to-May peak of 35 minutes. Those earlier nights continue to pull the six-month average upward, even though my more recent results are much lower. The percentage of each night spent in WHOOP's different stress zones makes the recent change especially clear. During the April-to-May peak: 6% of my sleep was in the high-stress zone 27% was in the medium-stress zone 67% was in the low-stress zone By August 14 through September 12: High-stress sleep had fallen to 1% Medium-stress sleep had fallen to 10% Low-stress sleep had risen to 89% This may be the most meaningful finding in the entire six-month trend. I did not simply spend less time in WHOOP's high-stress zone. A much larger proportion of my night shifted into the low-stress zone. From spring into early summer, my high Sleep Stress had already begun to decline as I was focused on my health routine it kept dropping—from 35 minutes to 18 and then 14 minutes. I was living my life as usual. Three observations help explain what I think this pattern means. Observation One The Spring Peak Was Worth Investigating The 35-minute average represented a 67% increase from the preceding monthly window. The nightly graphs also show more frequent and more substantial periods in WHOOP's high-stress zone during that time. Something was placing a greater physiological demand on my system, but the screenshots cannot tell me precisely what it was. The increase could have reflected emotional stress, training load, disrupted routines, sleep timing, travel, illness, temperature or several factors interacting at once. This is why wearable data becomes more useful when it is paired with context. The number shows us what changed. A behavior log helps us investigate why it may have changed. Observation Two The Improvement Began Before August My Sleep Stress did not suddenly improve in one week. After the April-to-May peak, it declined across four consecutive monthly windows: 35 minutes fell to 18, then 14, then 5 and finally 4 minutes. That suggests an ongoing recovery shift rather than one isolated good night. By the latest monthly window, 89% of my sleep appeared in WHOOP's low-stress zone, compared with 67% during the spring peak. My body appeared to be spending progressively more of the night in a lower state of physiological activation relative to my baseline. Observation Three One Change May Have Strengthened the Trend Then, on August 7, I changed one thing. My movement, training, sauna, hydration and sleep practices remained relatively consistent. The clearest variable I intentionally changed was this: I stopped drinking alcohol. The timing matters. My July 15-August 13 average, which contained only the first week of the alcohol-free experiment, was already down to 5 minutes. Because most of that monthly window occurred before August 7, alcohol removal cannot explain the entire decline. But after I removed alcohol, my Sleep Stress remained at its lowest level and fell again to 4 minutes. During the same period, my HRV increased, my resting heart rate decreased and my overall recovery improved. These measures are related rather than completely independent-WHOOP's Stress Monitor itself uses patterns in heart rate and HRV. Still, when several parts of my recovery picture begin telling a consistent story after one clearly defined change, the pattern becomes more compelling. The data does not prove that removing alcohol caused every improvement. The most responsible conclusion is that my recovery had already begun improving and alcohol removal may have helped reinforce and sustain that progress. My Biggest Aha Moment My biggest realization was this: I was not improving my sleep only by changing what I did at night-such as cooling the room, using a sleep mask or limiting phone use before bed. I was improving my nights by changing my days. This is exactly what Dr. Kristen Holmes suggested we do on EP 4054. Everything we do during the day contributes to the total load our bodies must process: The emotional stress we carry The timing and intensity of exercise The food we eat The time we eat it Alcohol Hydration Light exposure Travel Work demands And whether we create moments of recovery between those demands The night can become a physiological reflection of everything that came before it. For years, many of us have assumed that being exhausted guarantees a good night's sleep. But exhaustion and regulation are not the same thing. We can be deeply tired and still physiologically activated. The goal is not to exhaust the body until it shuts down. The goal is to help the body transition from meeting the demands of the day into the conditions required for recovery. How Can YOU Measure Nighttime Stress? WHOOP provides a specific Sleep Stress view, but you do not need WHOOP to begin observing your recovery patterns. Depending on the wearable or device you use, you may be able to track: Sleeping heart rate Resting heart rate Overnight HRV Respiratory rate Skin-temperature deviation Sleep disruptions Restlessness Blood-oxygen trends And recovery or readiness scores The most important consideration is your personal baseline. Your HRV, resting heart rate and respiratory rate should not be judged against someone else's ideal number. Begin by learning what is normal for you. Then look for: Sudden deviations Repeated elevations Changes lasting several nights Connections with specific behaviors (I noticed that sleep stress was ALWAYS there after no more than 1-2 glasses of wine) And whether multiple measures change together (I noticed that after a long hike, if I chose to have a drink that night, even one glass of wine, sleep stress would be there the next day). There was no escaping what elevated it for me. Even without a wearable, you can begin tracking subjective signs of recovery. Each morning, ask: How many times did I awaken? Did I feel restored when I woke up? Was my mind calm or racing before bed? Did I wake with tension, a racing heart or unusual warmth? How was my energy, mood and focus the following day? You can then compare those observations with factors such as: Alcohol Meal timing Exercise timing Emotional stress Illness Travel And changes in your sleep environment The purpose is not to become anxious about every fluctuation. The purpose is to find patterns that help you make better decisions. It did help me to have a wearable to notice just how consistent my sleep stress was with certain behaviors. Can you measure Sleep Stress without a wearable? Not in the same way. Without overnight heart-rate and HRV data, we cannot calculate WHOOP's Sleep Stress score—and we may not consciously feel that our physiology remained activated. That was true for me. I did not feel stressed while I was sleeping. I needed the data to show me that my body was experiencing something my conscious mind could not detect. Without a wearable, we can still watch for indirect clues: repeated awakenings, morning fatigue, an elevated morning pulse, daytime sleepiness or a bed partner noticing snoring, gasping or restlessness. A sleep diary can help connect those clues with our daytime behaviors. The wearable did not create the stress. It made an invisible physiological pattern visible. How Can We Lower Sleep Stress? There is no single method guaranteed to lower nighttime stress because the underlying cause may differ from one person to another. The following ideas are best approached as individual experiments. Examine Alcohol Alcohol can make us feel sleepy, but sedation is not the same as restorative sleep. Try reducing or removing alcohol for several weeks and observe what happens to your Sleep Stress, HRV, resting heart rate, awakenings and morning energy. Look for a trend rather than expecting every night to improve. This isn't the first time I've removed alcohol while creating certain conditions for my body to perform at its best over the past 7 years of this podcast, and prior. I remember first hearing Dr. Daniel Amen talking about how alcohol isn't a health food, and that he suggests no amount to be healthy for the brain. When I first heard him say this, I did think, “Oh come on, Dr. Amen, say it's not so” because I don't eat junk food (we'll cover this topic next) so I would almost look to find some research that would allow even just small amounts. You can hear what Dr. Huberman[vii] suggests on his riveting episode on this topic, and I'm sharing that my reduction with sleep stress was significant enough for me to decide that cutting it out of my diet would be a permanent decision. This is a personal decision though and what might be significant for me with my results, might not be what you notice. Finish Eating Earlier A large or heavy meal close to bedtime may keep the body active through digestion. Experiment with finishing dinner earlier and leaving a consistent interval before sleep. Then observe whether your nighttime heart rate, Sleep Stress or restlessness changes. I've always had dinner around 5pm and don't eat anything after 6:30pm (except the occasional hot chocolate). Create an Evening Wind Down The brain and body need a transition between daytime demands and sleep. Your off-ramp might include: Dimming the lights Reducing stimulating content Reading Meditation Slow breathing NSDR Gentle stretching A warm shower or bath Writing down tomorrow's priorities Or following a consistent bedtime routine The purpose is to give the nervous system repeated cues that the demands of the day are ending. I like an Epsom salt bath when I'm home to transition from a work day, to night time. Balance Training With Recovery Exercise generally supports sleep and long-term health, but timing and intensity can affect individuals differently. If you repeatedly notice elevated nighttime stress after late, intense workouts, experiment with completing those sessions earlier. You might replace a late high-intensity session with walking, gentle mobility or recovery work and then compare the results. I did notice that on days I go to the gym after work, I do have higher stress that next morning. It's not always easy to fit everything in early mornings. Practice Regulation During the Day Do not wait until bedtime to address accumulated activation. Small recovery periods throughout the day can include: Brief movement breaks Time outdoors Slow breathing Space between meetings Short periods without digital stimulation Meditation Recovery does not begin when your head hits the pillow. It is built into the rhythm of the entire day. Optimize the Sleep Environment Examine the physical conditions surrounding your sleep: Is the room comfortably cool? Is it dark? Is it quiet? Are notifications turned off? Are pets or other interruptions waking you? Does your bedding help regulate temperature? Has travel disrupted your routine? Sometimes the source of elevated nighttime activation is due to your environment. Pay Attention to Possible Health Signals A sudden increase in nighttime stress—especially when accompanied by changes in resting heart rate, respiratory rate or skin temperature—may occur when the body is fighting an illness. Persistent changes deserve attention, particularly if they are accompanied by loud snoring, gasping during sleep, chest symptoms, unusual shortness of breath or significant daytime sleepiness. A wearable cannot diagnose sleep apnea, an infection or another medical condition. Its role is to help us notice when something has changed and decide whether further evaluation may be appropriate. A Seven-Day Sleep Stress Experiment This week, select only one or two variables to change. Your experiment does not have to involve alcohol like mine did. I honestly just stopped enjoying it, so it was an easy variable for me to pick. Don't ask me to give up coffee though. I won't be participating in any caffeine reduction experiments. Choose one variable that may be influencing your nighttime physiology, keep everything else as consistent as possible, and watch the trend—not one isolated score. You might: Avoid alcohol Finish dinner earlier Move intense exercise away from bedtime Create a 20-minute evening wind down routine Practice five minutes of slow breathing Or make the bedroom cooler and darker Each morning, record: Time in high Sleep Stress, if available HRV Resting heart rate Respiratory rate Number of awakenings And how restored you feel on a scale from 1 to 10 At the end of the week, ask: What changed? What remained consistent? Which behaviors appeared to help my body settle? Which behaviors were followed by greater nighttime activation? Do not try to produce a perfect score. The goal is to identify a pattern you can repeat. Review and Conclusion To close out this BONUS EP4, where we explored Sleep Stress—not as another score to chase, but as a window into what the body may be experiencing while we sleep. We learned that Sleep Stress estimates how physiologically activated the body remains during the night. It is different from sleep duration, which tells us how long we slept, and sleep stages, which estimate the kinds of sleep we experienced. To understand this metric, we looked at the two primary branches of the autonomic nervous system. The sympathetic nervous system mobilizes energy so we can move, focus, respond and perform. The parasympathetic nervous system supports conservation, digestion, restoration and recovery. Neither branch is inherently good or bad. We need activation to meet life's demands, and we need the ability to downshift when those demands have passed. Healthy regulation is not the absence of stress. It is the flexibility to move between activation and recovery. We also learned that WHOOP does not directly measure either branch of the autonomic nervous system. It uses patterns in heart rate and heart-rate variability, compared with our personal baseline, to estimate physiological stress. That makes Sleep Stress a useful signal—but not a diagnosis and not proof of what caused a particular change. This metric fits within the recovery stage of our expanded Movement Loop: Movement → Physiological Load → Recovery → Adaptation → Performance Movement creates the challenge. But the challenge alone does not build greater capacity. The body must be able to absorb the load, recover from it and adapt. When I examined my own six-month results, I saw my average high Sleep Stress rise from 21 minutes to a spring peak of 35 minutes. It then declined across four consecutive monthly windows: 35 → 18 → 14 → 5 → 4 minutes That represented approximately 89% reduction from the highest month The proportion of my sleep in WHOOP's low-stress zone also increased from 67% during the spring peak to 89% in my most recent monthly window. My recovery had already begun improving before I had cut out alcohol on August 7, so alcohol removal cannot explain the entire decline. But when I kept the rest of my routine relatively consistent and removed alcohol, my Sleep Stress remained at its lowest level. At the same time, my HRV increased, my resting heart rate decreased and my overall recovery improved. This does not prove that one behavior caused every change. But it gives me good reason to believe that removing alcohol helped reinforce an already improving recovery pattern. And that brings me to the most important lesson from this experiment: I did not improve my recovery by asking my body to do more. I improved it by creating better conditions for my body to recover from everything it was already doing. So tonight, instead of asking only: “How many hours will I sleep?” Think about-- “What am I doing today that will help—or prevent—my body from settling tonight?” Because the night does not begin when we close our eyes. It carries the accumulated effects of how we moved, trained, ate, worked, regulated and recovered throughout the day. Movement creates the stimulus. Recovery allows us to absorb it. Adaptation builds our capacity. And greater capacity prepares the brain and body to perform tomorrow. I'll see you next time for Episode 407, where we will revisit Jason Wittrock's work through a current and carefully defined lens. We'll examine his experience with nutrition and fasting as the perspective of an applied practitioner and personal case study, while comparing those ideas with current evidence surrounding nutrition, blood-sugar stability, metabolic flexibility, recovery and performance. Because if recovery determines how well we adapt to a challenge, metabolism determines whether the brain and body have the energy required to power that adaptation. And the brain and body cannot sustain performance without the energy required to power the system. I'll see you next time.

She more than doubled her HRV in under a decade, and the behaviour that moved it most was not training, supplements or sleep duration, but going to bed and waking at the same time. This week I sat down with Global Head of Human Performance at WHOOP and author of Aligned, Dr Kristen Holmes, to unpack why sleep-wake consistency is the foundation of a resilient nervous system in midlife. WHAT YOU WILL LEARN - Why is sleep-wake consistency a stronger predictor of mortality and disease than how long you sleep? - How does the contrast between your day and your night affect the severity of menopause symptoms? - What is the physiological sigh, and why did it outperform other anxiety-reducing techniques in the research? - Can you really raise your HRV, and how much of it is genetic rather than modifiable? - Why does eating late at night suppress both sleep quality and overnight recovery? - Why do unresolved trauma and an outcome-driven identity keep your nervous system stuck in fight or flight?

Lake Michigan stunned him because it looked like the ocean. He had hoped to spot Wisconsin across the water. However, overcast skies and fog hid the far shore. He also apologizes for the hum in the previous episode, his first video session in the studio. Without headphones on, he took the noise for ordinary background sound. The culprit turned out to be a line-level cable plugged in at one end and loose at the other. After tracing it, he rewired the whole desk so every cable is neat and out of harm’s way. Meanwhile, he is still learning the studio’s TriCaster switcher and working on keeping his eyes on the camera. He invites listeners to send suggestions. Additionally, his grandmother had trouble finding the video version on the site. As a result, a site update is coming that uses the alternate enclosure feature, so listeners can switch between video and audio. Time with his grandmother has been a highlight of the trip. Cochrane reflects on how little time he spent with this side of the family after his father moved to Michigan. Next, he flies home to Oregon after some time in Detroit. As the move comes together, he also wants a better way to get recordings off the TriCaster than a USB drive.

The event streamed Wednesday as a pre-recorded film. It was also the first event under CEO John Ternus. He took over from Tim Cook, who became executive chairman, on September 1st. It took Apple seven years to answer Samsung’s first Galaxy Fold. Even so, the price barely moved, since the Duo starts at $1,999. Cochrane admits he hoped for something closer to $1,400. Still, based on the marketing alone, the Duo is the upgrade he is most excited about. The Duo is a book-style foldable that opens along a vertical hinge. Closed, it has a 5.4-inch outer screen and is roughly the size of a passport. Open, it reveals a 7.6-inch display, the largest Apple has put on an iPhone. Both screens share the same proportions, so apps simply scale up to fill the bigger screen. Opened flat, the Duo is just 5.2 millimeters thick, which makes it the thinnest iPhone Apple has built. Closed, it measures 11.3 millimeters and weighs 254 grams. By comparison, Samsung’s Galaxy Z Fold8 is lighter and thinner at 201 grams and 4.5 millimeters open. The Crease, the Hinge and the Return of Touch ID The crease was Cochrane’s biggest worry, since it is the most common complaint about folding phones. Apple layers the inner screen with a flexible plastic cover, thin glass, and a titanium plate underneath. Custom adhesives let those layers slide as the phone bends. On top, a microscopically etched matte finish scatters reflections to hide the crease. However, Apple only claims the crease is harder to see, not gone. Early hands-on reports split down the middle. Chance Miller at 9to5Mac found it “hard to notice a crease at most angles.” In contrast, Andrew Romero at 9to5Google, working from early videos, said it looks “just as visible” as on Samsung’s Fold8. The hinge uses more than a hundred parts and a row of magnets to hold the phone shut. Cochrane says it snaps open cleanly, which a $2,000 phone should. Notably, the Duo carries an IP68 rating, surviving six meters of water for up to 30 minutes. That matters on a foldable, because dust in the hinge is a classic way these phones die. The Duo also has no Face ID. Instead, a Touch ID fingerprint reader sits in the side button and works open or closed. Cochrane offers his own theory for the switch. With AI now able to generate convincing faces and video, a fingerprint may simply be the safer biometric. Inside the Duo: Chip, Cameras, Software and Battery The Duo runs the A20 Pro, the same chip as the iPhone 18 Pro, built on a two-nanometer process. A vapor chamber carries heat away so the phone can hold full speed longer. Cochrane welcomes that, since his own phone runs hot while charging or running demanding apps. Two 48-megapixel cameras sit on the back, a main and an ultra-wide. The outer screen unlocks the new tricks. For example, you can shoot selfies with the rear cameras, and Duo Preview lets your subjects see the shot. Smart Take snaps the photo when everyone is posing, and Kid Cue plays Peanuts animations to get kids to look at the camera. On the software side, the Duo ships with iOS 27.1. The Dynamic Island now runs vertically along the side, and Split View puts two apps side by side for the first time on an iPhone. Netflix, Zoom and Slack already support it. The Duo carries two batteries, one in each half, and Apple rates it for up to 24 hours of typical use. Charging to 50 percent takes about 20 minutes with a 60-watt adapter. However, that adapter is sold separately, which Cochrane calls out as a raw deal for first-time buyers. MagSafe and Qi2 wireless charging run at up to 25 watts. Storage starts at 256GB for $1,999 and climbs to $3,199 for 2TB. Preorders open October 16th, and the Duo reaches stores October 23rd. Ternus called it “the most transformational change to iPhone since the original.” Cochrane still wants one, though the price gives him pause, and he asks listeners whether they plan to buy. Apple Watch Series 12 Checks Your Heart Every Five Seconds Next, Cochrane turns to the Apple Watch Series 12 and its new Health Sensing System. The watch reads your pulse by shining green light into your skin and measuring what bounces back. After wrestling with the technical term, photoplethysmography, he notes that everyone sensibly calls it the optical sensor. Apple made those lights bigger and more efficient. As a result, the watch now checks your heart rate every five seconds, all day. It also measures heart rate variability, the tiny wobble between beats, as often as every five minutes. A bigger wobble generally means your body is rested and recovered. Cochrane loved Apple’s swimming ad, where a swimmer finishes his swim and checks his heart rate. To him, it feels far more futuristic than the rugged adventure watches of twenty years ago. Swim tracking itself isn’t new. What changed is the constant background check and a live heart rate readout on the watch face. All of that feeds a new daily readiness score from zero to ten. It weighs your recent activity, training load, vitals and sleep, then updates through the day. Engadget points out that competitors already offer readiness scores and faster sampling. In Cochrane’s view, Apple is catching up to the market, but doing it in a big way. Apple’s Heart Rate Accuracy Study Apple claims no wearable reads heart rate more accurately, and this time it published the study. Testers wore a Series 12 on one wrist and a rival on the other, with a Polar H10 chest strap as the reference. The rivals came from Garmin, Google, Huawei, Samsung, WHOOP and Oura. Across 1,254 people at five sites, Apple led in 139 of 159 comparisons. Eighteen were too close to call. The only two losses went to Google’s Pixel Watch 4 at rest, by less than half a beat per minute. Cochrane appreciated that a fifth of participants had the darkest skin tones, where optical sensors have historically struggled. The Series 12 comes in 42- and 46-millimeter sizes, including a new ceramic version. Battery life holds at 24 hours, and fifteen minutes of charging now buys up to twelve hours. Pricing starts at $399 for aluminum, $699 for titanium and $899 for ceramic. It reaches stores September 18th. Health Age and Apple’s Rebuilt Health App Cochrane admits he first misread this feature, and he is glad his initial read turned out wrong. Apple is rebuilding the Health app around Apple Intelligence, its umbrella name for its AI features. The app adds an Insights tab, a For You section, and a Longevity tab covering seven areas of health. Sumbul Desai, a physician who runs health and fitness at Apple, framed the goal. She said pairing the watch’s sensors with Apple Intelligence lets Apple “translate complex biometric data into clear guidance for users.” In other words, nobody wants to scroll through a spreadsheet of their own heartbeats. Inside the Longevity tab sits Health Age. It weighs your VO2 max, resting heart rate, sleep, and heart rate variability against your real age. You can also add lab results like A1c and LDL cholesterol. Apple’s sample screen shows a body running 3.9 years younger than its birthday. Cochrane finds the feature interesting, and he hopes the data stays private, much like health records at a hospital. However, Apple didn’t share the math behind Health Age. He would like Apple to publish its formula, because people will take a number like that seriously. The new app also adds at-home movement evaluations using the iPhone camera and the watch. Users can book a $119 blood panel covering more than 50 biomarkers at roughly 2,000 Quest Diagnostics locations. Cycle Tracking gains perimenopause and menopause support. The redesigned app arrives later this year, while watchOS 27 lands September 14th. Finally, Cochrane raises a concern about all this monitoring. He hopes Apple built strong safeguards around the health data, because a leak of data like this would bring serious lawsuits. Apple Watch Ultra 4 Can Outlast a 100-Mile Race The Apple Watch Ultra 4 shares nearly everything with the Series 12, from the sensors to the S11 chip. This year, what sets it apart is stamina. Normal use now reaches 50 hours, up from 42, and Low Power Mode stretches to 84. Meanwhile, fifteen minutes on the charger buys up to 18 hours, where last year’s model managed 12. A new Max Extended Workout mode tracks up to 45 hours of running or hiking, with GPS logging every second. Apple says that is typically enough to finish a 100-mile race. The watch also uses dual-frequency GPS, which listens to two satellite signals to reject readings bounced off tall buildings. DC Rainmaker came away impressed with both watches. As Ray Maker put it, “I’d argue they’re the biggest leaps in Apple Watch hardware and features since they launched the Ultra series back a few years ago.” The Ultra 4 holds at $799 and ships September 18th. Audio Intelligence and the Always-Listening Question Both new watches also gain a set of listening features Apple calls Audio Intelligence. Sound Recognition alerts deaf or hard-of-hearing users to sirens, alarms, doorbells, or a crying baby. Shazam names nearby songs without being asked. Then come the two raising eyebrows: Live Rewind and Siri Recap. Live Rewind shows the last fifteen seconds of your conversation as text with a double press of the Digital Crown. Siri Recap hands you a title and key points after a conversation, leaving out financial details and ID numbers. Both arrive in beta later this year, in English first, and need an iPhone 16 or newer. Cochrane saw the pushback coming. To replay fifteen seconds, the watch has to be listening before you ask. Apple answers with privacy promises, including that everything is opt-in and raw audio is deleted after processing on the chip. Still, he argues that opting in means choosing to give up privacy, and he has a hard time believing the processing stays on the device. AirPods 5 Bring Noise Canceling to $129 AirPods 5 comes in two versions, and the headline is price. Until now, noise cancellation in the regular AirPods cost $179. Both AirPods 5 models include it, starting at $129. Noise canceling is harder in the regular AirPods, because they lack the rubber tips that seal your ear. Apple’s AirPods marketing director Eric Treski admitted as much in 2024, calling it “really, really hard to create this great ANC quality in a non-ear-tip product.” Nevertheless, Apple says AirPods 5 removes up to 50 percent more outside noise than AirPods 4 with noise canceling. Interestingly, the chip and microphones are unchanged. The gain comes from reworked vents and ports in the shell, plus smarter software. For perspective, Apple says AirPods Pro 3 still cancel up to three times more noise. Gizmodo found AirPods 5 “did a good job silencing the background noise, but not entirely.” The $129 model charges over USB-C. For $149, you add a wireless charging case, a Find My speaker, a volume swipe on the stem, and an extra hour of listening. Both models also carry an IP57 rating and support Live Translation. They reach stores September 18th. How Apple Filmed the Event Cochrane closes by praising the production itself. Apple built different scenes and backgrounds throughout the film, and Six Colors noted a Hollywood backlot segment with a fake rainstorm, Roman soldiers, and astronauts. The closing card read “Shot on iPhone. Edited on Mac.” He still hopes to get an iPhone Duo, though he isn’t sure about paying two grand. For now, he may stick with his current phone. Cochrane wraps up by pointing listeners to the GNC Insider program, the newsletter, and podcastapps.com, adding that he likes Pocket Casts. Listeners can reach Ray or Chris at geeknews@gmail.com. He flies back to Oregon next, with another audio episode planned for Monday and a video site update coming this week. The post Apple’s September Event: iPhone Duo, Apple Watch Series 12, and AirPods 5 #1877 appeared first on Geek News Central.

Apple presentó por fin su plegable, el iPhone Duo, a 2.000 dólares y con un software completamente repensado para sus cuatro modos de uso, algo que ninguna otra marca se había molestado en hacer. También llegaron el iPhone 18 Pro con apertura variable en la cámara, unos AirPods 5 que bajan de precio, y un Apple Watch que apunta directo a Whoop.

Dominik hat sein EGYM-BioAge ermittelt – doch was sagt diese Zahl über seine Gesundheit aus? Wir erklären, was hinter dem biologischen Alter steckt und wie Studiogeräte, Wearables und epigenetische Tests zu ihren Ergebnissen kommen. Wie zuverlässig sind diese Werte?

We're building the world's largest longevity community: Join us at https://lifespan.com. Follow us on YouTube, Apple, and Spotify for new Lifespan episodes every 2 weeks.                               __________________________________________ This Lifespan episode explores how what we eat shapes how we age - from inflammation and blood sugar to the trillions of microbes living in our gut. Dr. Sinclair explains how diet affects key biological processes tied to metabolism, health, and longevity. Dr. Sinclair breaks down what sugar does inside the body, including glycation - the process by which sugar attaches to proteins and disrupts their function. The conversation also explores why inflammation rises with age, how the gut microbiome changes over time, and why our ability to sense and respond to nutrients can decline as we get older. Most importantly, Dr. Sinclair explains what we can do about it - from reducing dietary drivers of inflammation and excess sugar to supporting gut health and the nutrient-sensing pathways linked to longevity.  __________________________________________ Partners of the Lifespan show help us keep this program freely available as an educational resource while also supporting medical research.

We talk about aging like it happens to a whole person at once. It doesn't. It happens organ by organ, at different speeds, and most people never find out which part of them is running ahead until something breaks.Dr. Will Cole has spent sixteen years running one of the first functional medicine telehealth centers in the world, and he came to this conversation with a case that is both clinical and personal. In 2023 his father lost consciousness at the wheel and died in the crash. The autopsy pointed to cardiometabolic changes, and his heart cells had been aging faster than the rest of him. That same year, Stanford researchers found that one in five adults over fifty has at least one organ aging faster than the others, and that when it's the heart, the risk of a cardiac event more than triples.His new book with Dr. Josh Axe, Heal Your Cells, makes an argument that reframes most of what gets called normal aging. Exhaustion, brain fog, the weight that will not move, the hormone shifts nobody can explain. These are not the calendar. They are cells that have stopped reading their own instructions clearly, and that is a state you can change.We get into what actually makes a cell feel unsafe, why your gut lining is one cell thick and therefore the first thing to break, and the point almost nobody makes about elimination diets: the reintroduction matters as much as the elimination, and a protocol you never came off of is a cast you left on until the muscle atrophied.We also get into light. Not just morning sun, but the darkness half, which matters more for women than most people realize. Melatonin is not only a sleep hormone, it's one of the more important antioxidants for ovarian aging, and light levels most people would call almost nothing can cut its production substantially.Track your sleep, recovery, strain, and HRV with WHOOP. Get one month free at https://join.whoop.com/kaylabarnesOptimize your sleep with the Eight Sleep Pod. Get up to $350 off at https://www.eightsleep.com/Kayla with code “KAYLA”Join the most comprehensive *female-specific community for health and longevity optimization.* After over a decade dedicated to human performance and women's health, I created this space to share everything you need to know to optimize health and lifespan.

Managing people is a deeply human line of work—it requires relational skills, judgement, and deep knowledge of the people you work with. But Hilary Gridley believes that when used properly, AI can not only help you become a better manager, but can help your team make more meaningful use of their human skills. Hilary has spent years leading teams at companies like Whoop, and she's known for her work helping managers use AI to coach people, give feedback, and develop talent more efficiently. In this episode, Hilary makes the case for why AI belongs in management, and offers practical advice for how to help your team use AI in a way that adds value to their work instead of generating meaningless slop. Hilary and Molly also take a closer look at where many organizations have gone wrong in their adoption of AI tools, and the importance of clarity and communication within a team no matter what technology you have at your disposal.

Follow us on YouTube, Apple, and Spotify for new Lifespan episodes every 2 weeks. __________________________________________ In this episode of Lifespan, Dr. David Sinclair, A.O., Ph.D. - Professor of Genetics at Harvard Medical School and longevity scientist - and co-host Matthew LaPlante explore why we age, how aging begins long before its visible signs appear, and what we can do to slow aspects of cellular aging. They break down key drivers - or “hallmarks” - of aging, including mitochondrial dysfunction, stem cell exhaustion, and declining communication between cells, and explain how these changes can affect energy, inflammation, and the body's ability to repair itself. They also explore practical strategies including exercise, cold exposure, and molecules such as berberine, curcumin, metformin, and resveratrol, alongside emerging research into mitochondrial replacement and stem cells. Along the way, they tackle intriguing questions: When does biological aging begin? Why can identical twins age at different rates? Why does energy decline with age? And what can we do today to stay healthier for longer? __________________________________________ Partners of the Lifespan show help us keep this program freely available as an educational resource while also supporting medical research.

Die Silca Protocol Reifen (RCG und RCR) hypen gerade richtig! Noch ist sie keiner gefahren. Ist das Ganze ein Marketing-Scam oder können wir wirklich eine Reifenrevolution erwarten? Nach einem Jahr Whoop kann Ingo viel zum kleinen Tracker sagen. Gleichzeitig ist das Garmin Cirqa Band angekommen und klar: Kein Abo, was der Pferdefuß bei Whoop ist, aber die Unterschiede liegen woanders: Das Whoop kaschiert die Technik und alle anderen Bänder sehen aus wie Schrittezähler von vor 10 Jahren. Dazu ein paar interne Informationen zu unserem Lagerumzug und Umbau und mein OPEN UPPER Upcycling zum Pendelrad.

On this week's episode of the WHOOP Podcast, WHOOP Global Head of Human Performance and Principal Scientist Dr. Kristen Holmes and WHOOP SVP of Research, Algorithms, and Data Emily Capodilupo take a deep dive into the science of women's health. The two define the importance of understanding how a woman's physiology changes across the lifespan. Dr. Holmes and Emily define the various phases of the menstrual cycle and how each influences sleep, recovery, thermoregulation, fueling, and exercise performance. This episode challenges the idea that women need to completely restructure their training around their cycle. Instead, Dr. Holmes and Emily explain how understanding your individual patterns can help you make small, informed adjustments to strain, sleep, and recovery that better support your body.The conversation examines the menstrual cycle as an important signal of overall health, establishing your own physiological baseline, and how changes in those patterns can provide useful information throughout different stages of life. Dr. Holmes and Emily discuss the extensive research WHOOP has conducted across women's health, including pregnancy, fertility, and menopause, exploring how wearable data can help reveal changes that might otherwise be difficult to recognize. Ultimately, this episode highlights how better data, more research, and a more personalized understanding of female physiology can give women greater agency over their health and performance at every stage of life.Buy the new Meridian band(00:00) Trailer(01:02) WHOOP Research: The Importance of Studying Women's Health(03:23) Recovery Through The Menstrual Cycle(06:01) Using Science-Back Research to Develop WHOOP Features(09:12) Menstrual Cycle Variability Insights(12:16) Fuelling Tips for High Performing Women(19:27) Viewing Your Menstrual Cycle as a Vital Sign(21:49) Signs of RED-S and Misalignment(24:17) Early Signs of PMOS and How To Screen For It(28:28) What Your Body Is Trying To Tell You(29:49) What Women Need To Know About Tracking Their Cycle(20:10) How To Advocate For Care(30:56) Importance of Knowing Your Normal (31:22) Early Warning Signs of Perimenopause(32:54) WHOOP For Symptom Tracking(40:26) Sleep Hormone Feedback Loop(43:11) What Male Partners Need To Know(46:44) Pregnancy Research Gaps: What We Know About Pre-Natal Training(53:32) Maternal Care & Recovery(56:12) Exciting New Leads in Women's HealthSupport the showFollow WHOOP:Sign up for WHOOP Advanced LabsTrial WHOOP for Freewww.whoop.comInstagramTikTokYouTubeXFacebookLinkedInFollow Will Ahmed:InstagramXLinkedInFollow Kristen Holmes:InstagramLinkedInBuy Aligned by Dr. Kristen Holmes: Follow Emily Capodilupo:LinkedIn 

In this episode of *Pediatric Perspectives*, I was joined by Kari Bundy, a health freedom advocate whose son Mason died three days after his four-month vaccines, and by Polly Tommey, who turned the interview around to ask me about pertussis, the DTaP/Tdap vaccine, and SIDS. Kari's story is a hard one, but it's the kind of story parents deserve to hear before they're standing in an exam room being told their baby needs a shot right now.

Episode 234: In this episode of Sports Science Insights Podcast, host Steve Barrett is joined by Niklas Virtanen, who leads the sport science efforts at FC Midtjylland. With over eight years of experience in elite sport and high-performance consulting, and backed by UEFA fitness coaching and physiotherapy credentials, Niklas has built his work around a data-driven approach to optimising player performance and development. Much of the conversation starts from a premise that is easy to say and harder to sit with: GPS has been mastered. Total distance, high-speed running, sprint counts — the metrics that once felt like the frontier are now table stakes, tracked by almost every club at almost every level. The interesting question is no longer whether you can collect them, but what you do once collecting them stops being a competitive advantage. ㅤ From there the discussion turns to what sits underneath the movement data. Niklas makes the case for IMA and IMU signals as a way of understanding how a player is performing an action, not just what action they performed — the accelerations, decelerations, changes of direction and mechanical signatures that separate two players covering identical distances in completely different ways. It's a shift from describing workload to interpreting quality, and it changes what sport science can offer a coach. ㅤ The episode also explores where that leaves practitioners: the discipline required to stop adding metrics, the value of asking better questions of the data already being captured, and what genuine progress looks like once the obvious layer has been solved. ㅤ Topics Discussed: GPS Is Mastered — So What Should We Be Doing Now? Using IMA/IMU Data to Understand How a Player Is Performing, Not Just What They're Doing Moving from Workload Description to Movement Quality What Progress Looks Like Beyond the Obvious Metrics Where you can find Niklas: LinkedIn Instagram — Sponsors Axon: Performance teams spend the morning after game day stitching together six systems before the coach gets an answer.

The Big Unlock · Dr. Ami Bhatt, Chief Medical Officer, WHOOP In this episode, Dr. Ami Bhatt, Chief Medical Officer at WHOOP and former Chair of the FDA Digital Health Advisory Committee, explores how healthcare can embrace AI without losing the clinical judgment, human connection, and context essential to patient care. She sees AI as a powerful source of compute that can surface knowledge, identify patterns, and help clinicians navigate growing volumes of health data, while clinical acumen remains central to decision-making. Dr. Bhatt emphasizes that digital health and Agentic AI must start with the patient, incorporate individual preferences, and establish clear guardrails for when human intervention is required. She also highlights wearables as an important bridge between community-based monitoring and clinical care. Dr. Bhatt highlights the need for post-deployment monitoring and real-world evidence as AI systems continuously evolve, and calls for closer collaboration among patients, clinicians, technology companies, and regulators. She urges healthcare leaders to prepare for constant technological change, develop stronger digital infrastructure, and focus innovation on unmet patient needs rather than technology for its own sake. Take a listen. This episode was recorded in July 2026. Dr. Bhatt is now Chief Medical Officer at WHOOP.

In this episode Andrea Samadi explores how movement and sleep work together in a "brain operating system" for human performance, focusing on restorative sleep (deep + REM), personal WHOOP data, and the trade-offs created by early-morning exercise. She shares four lessons and a simple experiment to help listeners protect REM and deep sleep while maintaining an active life, emphasizing weekly rhythms, small changes, and tracking patterns rather than chasing perfect numbers. SEASON 16 | BONUS EPISODE 4 RESTORATIVE SLEEP Where Adaptation Happens Why deep sleep restores the body, REM helps integrate experience, and healthy habits must work together. ON BONUS EPISODE 4, YOU'LL LEARN: ✔ What restorative sleep really measures ✔ How deep sleep and REM support different forms of recovery ✔ Why REM percentage and duration tell different stories ✔ What my six-month sleep data revealed ✔ The hidden tradeoff behind my 4:00 AM hiking routine ✔ What happened when I slept just 21 minutes longer ✔ Why healthy habits can sometimes compete ✔ How to protect sleep without giving up movement ✔ 4 Lessons and a simple experiment for discovering your own best rhythm Episode Introduction Welcome back to the Neuroscience Meets Social and Emotional Learning Podcast, where we bridge neuroscience, social and emotional learning, and human performance to create measurable improvements in well-being, achievement, leadership, productivity and results. I'm Andrea Samadi, and throughout Season 16 we have been building what I call the Brain's Operating System for Human Performance—a neuroscience-based framework for understanding how the systems of the brain and body work together to influence how we learn, adapt, connect, lead and ultimately perform. We are currently in Phase 3: Movement, Learning and Cognition. Movement is the foundation of this phase because it affects far more than our muscles. When we move, we activate processes throughout the brain and body. Movement supports neurogenesis—the development of new neurons—particularly in areas involved in learning and memory. It strengthens connections between neurons through synaptic plasticity. We covered neurogenesis on EP 141[i] if you want to revisit that episode, if you are as curious as I am about how to regrow our brain cells. Movement that we are learning in this phase, also influences brain chemicals such as dopamine, serotonin, norepinephrine and acetylcholine, which affect motivation, mood, attention and learning. Movement can also strengthen our resilience by helping us manage stress and become more emotionally flexible. It builds sleep pressure, (the longer we stay awake, the more adenosine accumulates that increases our need or “pressure” to rest) which can support deeper, more restorative sleep. And over time, these changes may contribute to greater creativity, insight, endurance and human potential. But movement only creates the stimulus. The benefits don't come from movement alone. They come from the way the brain and body respond to that movement—and that response is called adaptation. Movement changes the brain. Adaptation changes the body. Recovery is what connects the effort we make today with the strength, resilience and capacity we hope to build tomorrow. Without adequate recovery, we can receive the stimulus without fully receiving the benefit. That is why sleep belongs inside the Movement Loop. Sleep is not separate from movement, learning or performance. It is one of the primary places where the brain and body respond to what we have asked them to do. Throughout Season 16, I've been sharing some of my own health and performance data as a living case study—not because everyone should try to reproduce my numbers, but because our individual trends can help us understand how neuroscience shows up in everyday life. I thought that if I was curious about understanding my numbers—and using them to improve my health, well-being and productivity—then other people might benefit from what I've learned along the way. My data has helped me see that movement, recovery and performance cannot be understood in isolation. They work together as a system: Movement creates the stimulus. Recovery creates the conditions for adaptation. Restorative sleep is one of the places where that adaptation unfolds. And this brings us to one of the most important recovery metrics I've learned to follow: Restorative sleep. We often celebrate what happens while we're awake: Our productivity. Our focus. Our learning. Our movement. Our performance. But much of the adaptation supporting those abilities happens while we sleep. Deep sleep supports physical restoration. REM sleep supports emotional processing, memory integration and cognitive flexibility. Together, these stages help convert the demands of one day into greater capacity for the next. This episode began with one honest question about my own routine: THE QUESTION: What am I gaining by waking at 4:00 AM to hike—and what might I be giving up by not sleeping longer? This is not simply an episode about sleeping more. It is about creating a rhythm in which two essential health behaviors—sleep and exercise—support one another instead of competing for the same limited hours. You will see my data exactly as it is. Sleep is one of the weaker links in my current health routine, which makes it a useful place to learn. The goal is not to judge the data. The goal is to let the data ask a better question. Lesson 1: Restorative Sleep Contains Two Stories WHOOP (the wearable device that I use to measure sleep) defines restorative sleep as the combined time spent in deep sleep, also called slow-wave sleep, and REM sleep. Combining the two creates a useful overview, but separating them reveals two different parts of the story. Deep Sleep or Slow-Wave Sleep: Physical Restoration Deep sleep is concentrated more heavily in the earlier part of the night and supports processes associated with physical restoration. It is relevant after hiking, Zone 2 exercise, strength training and other demanding activity because sleep is part of how the body responds to the strain we create. During deep sleep: Tissue repair is supported. Growth hormone release increases. Immune function is supported. Energy is restored. The body adapts to physical strain. REM Sleep: Integration REM stands for rapid eye movement sleep and is known as the “mentally restorative” stage of sleep. This is where most dreams occur, and short-term memories are converted into long-term memories. During REM, the brain is highly active while most voluntary muscles remain temporarily inhibited. I'll never forget the part of our interview with Dr. Jaland Balal[ii], when he explained that this feature is what keeps us safe from moving around too much while we are sleeping, keeping our sleeping partners safe. REM has been associated with: Emotional processing Memory integration Aspects of learning Cognitive flexibility Creative associations Connecting new information with previous experiences Memory is supported across several sleep stages—not by REM alone. REM helps the brain process, connect and integrate. REM periods also tend to become longer as the night progresses. That means shortening the end of the sleep window may disproportionately reduce the opportunity for the longer, more REM-rich cycles that occur toward morning. Deep sleep helps restore the body. REM helps integrate the brain. We need both. That second sentence is personally meaningful because I have logged my dreams for years. A dream is not a diagnosis or a literal solution, and dreams can occur outside REM. But a dream log gives me a qualitative record of recurring emotions, images, relationships, problems and emerging ideas that my mind may still be processing. Since I enjoy learning, interviewing, writing, teaching and connecting ideas across neuroscience and social-emotional learning, REM matters for more than dream recall (which by itself is fascinating and something we will look deeper at in Phase 5 with Integration and Meaning). Lesson 2: My Data Revealed a Duration Gap When I looked at my WHOOP trends, the total restorative-sleep number was only the beginning.   Metric My average   Six-month restorative sleep 2 hr 43 min   Lifetime REM 1 hr 37 min   Last 90 days REM 1 hr 18 min   Last 30 days REM 1 hr 20 min   Recent REM percentage About 20% When I looked at six months of WHOOP data, my average restorative sleep was: 2 hours and 43 minutes per night. That number gave me the total time spent in deep sleep and REM—but it did not tell me how those two stages were distributed. When I separated them, another story emerged. My lifetime REM average was approximately: 1 hour and 37 minutes per night. But over my more recent periods, that changed: Last 90 days: approximately 1 hour and 18 minutes Last 30 days: approximately 1 hour and 20 minutes Recent REM percentage: approximately 20% of my total sleep Twenty percent is within a commonly reported adult range. But compared with my own lifetime average, my recent REM duration was approximately 17–19 minutes lower per night. That distinction matters. My REM percentage may appear healthy while my total REM duration is still lower than my personal historical average. So my real question became: Not “Is my REM normal?” but “What conditions help my brain produce more of its own normal REM?” This is the value of tracking. THE DATA LESSON: A population range provides context. Your baseline provides the story. Your trend gives you a question to test.           Lesson 3: The 4:00 AM Tradeoff I love hiking early. It gives me cardiovascular conditioning, time outside, morning light, mental clarity and consistency. In Arizona, it also helps me finish before extreme heat heats around 8am. But if I go to bed at 8:30 PM and wake at 4:00 AM, I create a maximum sleep opportunity of seven and a half hours. That is time in bed—not necessarily time asleep. It does not include the time required to fall asleep or periods of wakefulness during the night. If I remain in bed until 6:00 AM, I create two additional hours of sleep opportunity. Those two hours would not equal two hours of REM. They would contain a mixture of sleep stages and perhaps brief wakefulness. But because REM episodes generally lengthen later in the night, the added opportunity may protect some of the more REM-rich portion of sleep. If you want to understand sleep cycles, I highly recommend taking Dr. Mathew Walker's Masterclass[iii] The Science of Better Sleep. What the Early 4am Wake Gives Me Early movement and consistency Cardiovascular conditioning Time outdoors and morning light The mental and emotional benefits of hiking What Might it Cost Me Up to two hours of total sleep opportunity (lost) Part of one or more later sleep cycles (lost) Greater opportunity for REM and dream recall (important to me) Time for memory and emotional processing across sleep (important to me) The accurate interpretation is not that I lose two hours of REM. It is that I may give up two hours of sleep opportunity containing some of the night's more REM-rich cycles. That led to my central realization: healthy behaviors (like my early wake to hike) can compete when their timing is not coordinated. MY AHA MOMENT: Am I creating better sleep through movement—or repeatedly borrowing from the final part of sleep to make that movement happen? My wearable cannot prove that early wake times caused the change. Consumer wearables estimate sleep stages; they do not measure them with clinical polysomnography. But the pattern gives me a reasonable hypothesis to test. That is what self-tracking should do: not make us anxious about a number, but help us ask a better question. A Real-Time Clue: What 21 More Minutes Revealed While preparing this episode, my data gave me a real-time example of the tradeoff. On Thursday, August 27, I woke at 4:21 AM instead of 4:00 AM. That night I recorded three hours and two minutes of restorative sleep—the highest total of the week. It included one hour and seven minutes of deep sleep and one hour and 55 minutes of REM. That REM duration was approximately 35 minutes above my recent 30-day average. My graph in the show notes showed a substantial REM period close to the end of the sleep window. Twenty-one additional minutes cannot explain a 35-minute difference, and one night cannot establish cause. Sleep varies from night to night. But the observation supports the hypothesis that a 4:00 AM alarm may sometimes interrupt a REM period already underway. I also remembered my dream and added it to my dream log. That gave me another kind of data: not just how long I slept, but what my mind may have been processing, integrating or connecting. One night is a clue—not proof. Watch the trend. The lesson is not that 4:21 AM is a magical wake time. The lesson is that the final portion of sleep may be more valuable than its length makes it appear. A small extension may sometimes allow the brain to finish a cycle that an earlier alarm (or your natural body's alarm) would interrupt. Lesson 4: Build a Rhythm, Not a Perfect Day The remedy I've concluded is not to stop hiking, (I would be miserable) and it is not to maximize sleep or exercise in isolation (I wouldn't feel productive sleeping in longer). The solution is to create a weekly rhythm in which movement provides the stimulus and sleep protects the opportunity for adaptation. For me, that rhythm can include two kinds of days: 1. Early-Hike Days (twice a week) When a 4:00 AM wake time is necessary, (and possible). I can treat bedtime as part of the training plan. If family responsibilities the night before make a very early bedtime unrealistic, I can recognize that constraint and adapt. But it is important that I get to bed by 8:30pm if I want to wake up 4am.   2. Sleep-Protected Mornings On selected non-hiking days, I can remain asleep until approximately 5:00 or 6:00 AM and move later.  These mornings create more opportunity for later sleep cycles and give me a comparison condition for my experiment. What happens if I stay in bed longer? The goal is not a perfect day. The goal is a sustainable week. The Movement Loop is not: Move → Move More → Keep Pushing. It is: Movement → Recovery → Adaptation → Performance → Greater Capacity. For you, the listener, are you giving yourself enough time to recover? To Adapt? To Increase Performance? That leads to greater capacity? Or, did you notice, like me, that there was a trade off with your schedule? Tips to Implement: Run Your Own Restorative-Sleep Experiment You do not need my wake time, my REM number or a WHOOP device to learn from your own pattern. Use this five-step experiment for two to four weeks. Establish your baseline. Record your usual bedtime, wake time, estimated sleep duration, morning energy and—if available—deep and REM sleep for at least seven nights. The Whoop device rewards users who go to bed, and wake at the same time, calling it sleep consistency. Choose one change. Add 20–60 minutes of sleep opportunity on selected mornings, or move bedtime earlier before early-training days. Avoid changing every variable at once. Stanford Professor, Dr. Andrew Huberman[iv] suggests that if you can find a way to add heat to your sleeping environment in the final 2 hours of your sleep, it can increase your REM sleep. Sleeping just 21 more minutes for me made a notable difference. Protect movement differently. On sleep-protected mornings, move later, shorten the session or choose a lower-intensity option instead of skipping movement entirely. This was the game changer for me.  I opted for a walk on sleep protected days. Track a small set of outcomes. Use total sleep, restorative sleep or dream recall if available, morning clarity, afternoon energy and exercise quality. Optional wearable metrics include recovery, HRV and resting heart rate. This is where you have to notice what you see from this ONE change. It might be obvious like mine—I noticed that extra time led to a dream that I could recall. Review the pattern—not the best night. Compare at least one or two weeks of early mornings with sleep-protected mornings. Look for a repeatable combination that supports both recovery and movement. The patterns will reveal whether the ONE thing you changed made a difference for you. If you do use a wearable, remember that sleep stages are estimates. Use the device to compare patterns under similar conditions, not to diagnose a sleep disorder or chase a perfect stage score. KEY QUESTION: Can I preserve the benefits of movement without repeatedly borrowing the time my brain and body need for recovery? A Bigger Experiment Is Still Underway I have also removed one significant sleep disruptor and am tracking what happens to my REM, sleep stress, HRV, resting heart rate and recovery. I do not want to draw conclusions too early. I want enough data to distinguish a temporary response from a genuine physiological shift, so I will return to that experiment in a future episode. For now, the question is narrower: how can I protect restorative sleep while continuing to live an active life? Review  To review and conclude this week's BONUS EP 4, let's bring the four lessons—and the data—together. Lesson 1: Restorative Sleep Contains Two Stories Restorative sleep combines two important stages: Deep sleep and REM sleep. Deep sleep supports physical restoration and adaptation. REM supports emotional processing, memory integration, cognitive flexibility and creative association. We need both. Every morning, I look at my restorative-sleep total and hope it is closer to three hours than two. But this episode taught me not to stop at that combined number. The total gives me the overview. Deep sleep and REM tell me how that restoration was distributed. And REM is personally meaningful to me for another reason: I have recorded my dreams for years. Dream recall does not provide a literal interpretation of everything happening in my life. But it gives me a qualitative record of the emotions, experiences, problems and ideas my mind may still be processing. So Lesson 1 is: Restorative sleep is not one number. It contains the story of how the body restores—and how the brain integrates. Lesson 2: My Data Revealed a Duration Gap Over the past six months, my average restorative sleep has been two hours and 43 minutes. My recent REM has represented approximately 20% of my total sleep—a percentage that may appear reasonable. But when I looked at duration rather than percentage, I discovered that my recent REM was approximately 17–19 minutes below my lifetime average. REM percentage and REM duration answer different questions. Percentage tells me how my sleep was distributed. Duration tells me how much actual time my brain spent in that stage. That distinction matters because someone can have a reasonable REM percentage but still receive less total REM when the overall sleep window is shortened. So Lesson 2 is: A percentage can look healthy while duration still reveals a gap. This is why personal baselines are so valuable. Our trends help us identify the question we need to investigate. Lesson 3: The 4:00 AM Wake Time Creates a Tradeoff My data led me to examine my 4:00 AM wake time. Waking at 4:00 does not mean I am losing two hours of REM. It means I may be giving up two hours of total sleep opportunity—time that could contain approximately one to one-and-a-half later, more REM-rich sleep cycles. Then, while I was preparing this episode, I received an early clue. When I slept just 21 minutes longer—waking at 4:21 instead of 4:00—my restorative sleep reached three hours and two minutes. That included one hour and seven minutes of deep sleep and one hour and 55 minutes of REM—approximately 35 minutes more REM than my recent 30-day average. I also remembered my dream and added it to my dream log. Twenty-one additional minutes cannot explain the entire 35-minute difference, and one night does not prove causation. But the graph showed a substantial REM period close to the end of my sleep window. That gave me a clue worth investigating: My 4:00 AM wake time may sometimes interrupt a REM period that is already underway. So Lesson 3 is: The final portion of sleep may be more valuable than its length makes it appear. This does not mean that 4:21 is a magical wake time. It means that a small extension may sometimes allow the brain to finish a cycle that an earlier wake time would interrupt. Dr. Huberman, and Dr. Holmes offered tips to stay in bed longer, to capture REM rich sleep time. Lesson 4: Build a Rhythm, Not a Perfect Day My early-morning hikes provide cardiovascular conditioning, time outside, morning light, mental clarity and emotional regulation. They support my health. They also make me happy. The remedy is not to stop exercising and become miserable. The remedy is to protect sleep as well as I realistically can and arrange movement around a more complete sleep window. That might mean saving selected mornings for longer sleep. It might mean moving later on non-hiking days. It might mean moving bedtime earlier when possible. And it might mean shortening a workout when sleep has been limited. The goal is not to maximize sleep or exercise in isolation. It is to create a sustainable weekly rhythm in which both can happen. So Lesson 4 is: The best routine is not the one that produces a perfect number. It is the one that allows the whole system to work. Now let me ask you: Do you know how much restorative sleep you receive? Do you look beyond the total and examine both deep sleep and REM? Are you tracking percentages—or actual duration? Does your schedule give you enough sleep opportunity? And could one healthy behavior in your life be unintentionally competing with another? My restorative-sleep average gave me the overview. My REM duration revealed the tension. My 4:00 AM wake time created the hypothesis. My additional 21 minutes gave me an early clue. My next step is to test a better rhythm. That is what measurement is supposed to do. Not judge us. Not pressure us to produce a perfect number. Guide us toward a better decision. I hope this deeper look at restorative sleep encourages you to identify one small experiment of your own—not to chase a perfect number, but to discover the rhythm that helps you learn, adapt and perform at your best.   We'll see you next time as we return to Dr. John Medina's work—not to repeat what we have already learned about attention, but to answer the next question in the Movement Loop: once movement activates the brain, how does attention determine what becomes learning? From there, we'll revisit Jason Wittrock's work through a new lens: how metabolic health, nutrition and energy availability help the brain and body sustain movement, recovery and performance. Resources and Episode Pathway Phase 1: Regulation & Safety The Foundation Core Question: Is the nervous system safe enough to learn? Everything begins with regulation. Before we can focus, learn, lead, or perform, the brain first asks one fundamental question: Am I safe? Throughout Phase 1, our guests showed us that regulation isn't simply about reducing stress—it's about creating the biological conditions that allow the brain to learn, adapt, and thrive. Together we explored: Baland Jalal – how sleep, curiosity, imagination, and creativity prepare the brain for learning. https://andreasamadi.podbean.com/e/hypnagogic-genius-capture-your-best-ideas-at-the-edge-of-sleep/   Dr. Bruce Perry – why regulation, rhythm, and relationships form the foundation of every healthy nervous system.  https://andreasamadi.podbean.com/e/safety-first-why-a-regulated-brain-is-the-key-to-learning/   Dr. Sui Wong – how lifestyle medicine and autonomic balance build lifelong brain resilience. https://andreasamadi.podbean.com/e/your-eyes-the-brain-s-early-warning-system/   Rohan Dixit – how heart rate variability gives us real-time feedback on our ability to regulate stress. https://andreasamadi.podbean.com/e/breathe-to-reset-how-hrv-tech-reveals-hidden-stress/   Dr. Kristen Holmes – how recovery metrics reveal our physiological readiness to perform. https://andreasamadi.podbean.com/e/kristen-holmes-from-whoopcom-on-unlocking-a-better-you-measuring-sleep-recovery-and-strain/   Dr. Antonio Zadra – how sleep and dreaming consolidate memories, regulate emotions, and generate insight. https://andreasamadi.podbean.com/e/when-brains-dream-how-sleep-integrates-emotion-insight-and-creativity/ Together these conversations taught us that sleep and stress regulation aren't optional—they're the operating system that allows every higher brain function to work. Phase 2: Motivation & Neurochemistry The Direction Core Question: What moves us into action? Once the brain feels safe, it becomes ready to pursue goals. In Phase 2, we explored the internal chemistry that transforms intention into action. Our experts helped us understand that sustainable motivation isn't about willpower—it's about aligning our beliefs, thoughts, attention, energy, and movement. Together we discovered: Bob Proctor — our beliefs determine the direction of our lives. https://andreasamadi.podbean.com/e/belief-first-the-neuroscience-of-motivation/   Dr. Carolyn Leaf — our thinking literally changes our brain chemistry. https://andreasamadi.podbean.com/e/thoughts-as-biology-how-your-mind-shapes-neurochemistry/   Dr. John Medina — attention determines what the brain encodes and remembers. https://andreasamadi.podbean.com/e/theory-of-mind-the-missing-link-between-attention-reward-and-motivation   Dr. Anna Lembke- Dopamine, Motivation and Why the Brain Repeats Behavior https://andreasamadi.podbean.com/e/dopamine-nation-the-pleasure%e2%80%93pain-balance-that-drives-motivation/   Dr. Friederike Fabritius — managing our energy allows high performance to become sustainable. https://andreasamadi.podbean.com/e/fun-fear-focus-closing-the-motivation-loop/   Dr. Chuck Hillman & Paul Zientarski — movement activates the brain, preparing it to learn. https://andreasamadi.podbean.com/e/move-to-learn-how-movement-activates-the-brain-and-fuels-motivation/   By the end of Phase 2, we introduced what became The Motivation Loop, showing how beliefs influence thoughts, thoughts influence actions, actions create results, and results reinforce future beliefs. Phase 3: Movement, Learning & Human Performance The Transformation Core Question: How does movement change the brain—and how does recovery transform that change into performance? Now we're taking the next step. Phase 3 builds on everything we've learned so far. If Phase 1 created a regulated nervous system... If Phase 2 created motivation and direction... Phase 3 explains how the brain and body actually become stronger. Together we've explored this process through conversations with: Dr. Chuck Hillman & Paul Zientarski — why movement activates the brain before learning. https://andreasamadi.podbean.com/e/movement-first-how-a-20%e2%80%91minute-walk-lights-up-the-brain/   Dr. John Ratey — how exercise builds a healthier, younger brain. https://andreasamadi.podbean.com/e/movement-matters-how-every-move-rewires-the-brain/   Dr. Kristen Holmes — why recovery determines adaptation and readiness. https://andreasamadi.podbean.com/e/movement-isnt-enough-how-recovery-drives-real-adaptation   Dr. John Medina — how attention transforms movement into lasting learning. Jason Whitrock — how metabolism and cellular energy fuel long-term performance. WHERE WE ARE GOING NEXT Phase 4 — Connection, Emotion & Social Intelligence The Human System Core Question: How do we thrive with other people? The brain didn't evolve in isolation—it evolved through relationships. In Phase 4, we'll explore emotional intelligence, empathy, communication, trust, leadership, and psychological safety to understand how our relationships shape learning, well-being, and performance. Phase 5 — Integration & Human Performance The Complete System Core Question: How do all the systems work together? In our final phase, we'll bring everything together—regulation, motivation, movement, emotion, relationships, learning, and recovery—into one integrated framework. We'll discover how these systems work together to create measurable improvements in our well-being, achievement, leadership, productivity, and results.

In this episode of Unfiltered Waters, Elizabeth Beisel and Todd Anderson fill in for Katie Hoff, a week from having her baby girl, and sit down with Team USA breaststroker McKenzie Siroky right before the Pan Pacific Championships. She's coming off a personal best in the 100 breast at nationals, capping two hard months when her stroke feel vanished. She tracks nearly every metric of her training. So how does one of the most data driven swimmers on the team find her way back by feeling instead of measuring?McKenzie ranks her outside of pool priorities: nutrition first, then recovery and sleep, then mental work like meditation and breath control with a sports psychologist she calls Dr. Joe. She wears a Whoop and has hit strain scores over 20, though she ignores it on race day, going best times in yellow and red. Her best lift is a 195 pound bench, chasing 200 right after Pan Pacs. Todd asks about the suit that ripped fifteen minutes before her nationals final, and she walks through the breathing reset that got her back on the block.Along the way, the conversation goes places most swim interviews don't: hosting the team for Saturday pancake brunches off her Blackstone griddle, thirty pancakes at a time, plus wood fired pizza nights with homemade sourdough crust. She traces her breaststroke to family history, her mom swam at Michigan State too. She and teammate Moana treat practice like an actual race, speaker on the deck included, to rehearse the nerves. She admits she doesn't always know what a lactate based target split is supposed to feel like, she just trusts it and goes.Underneath the technical talk is a real account of what it costs to lose your feel for the thing you're best at. McKenzie describes two months so frustrating she was near tears most practices, calling her aunt and dad from the car to find one thing to control each day. The fix wasn't more structure, it was less: slower practice, no intervals, feeling her stroke again instead of measuring it. It's a lesson that lands harder given how much of her identity runs on tracking numbers, a contradiction Elizabeth is well suited to draw out of her.Whether you're a swimmer who tracks every number in training or someone who has never touched a pool but loves a good return to form story, this episode delivers.

On this week's episode of the WHOOP Podcast, WHOOP Founder and CEO Will Ahmed sits down with WHOOP Global Head of Human Performance and Principal Scientist Dr. Kristen Holmes to discuss her new book, Aligned, and what it takes to build a more resilient nervous system. Drawing on her journey from elite athlete to championship-winning coach, researcher, and human performance expert, Dr. Holmes shares what she's learned about the connection between recovery, resilience, and sustained performance. Will and Dr. Holmes explore why the time spent away from your craft can be just as important as the work itself, how sleep consistency and HRV can provide insight into the health of your nervous system, and why balancing stress with adequate recovery is critical for performing at your best. Dr. Holmes also breaks down her HEAL framework, explores how trauma and an outcome-driven mindset can shape our behaviors, and shares practical strategies for building greater agency, resilience, and alignment in everyday life.Buy Aligned by Dr. Kristen HolmesShop Meridian by WHOOP(00:00) Trailer (00:55) Introduction to Aligned by Dr. Kristen Holmes(02:25) How A Healthy Nervous System Promotes Healthy Aging(05:31) Impact of Childhood Trauma on High Performers(08:22) 70% of Americans Experience Trauma(10:15) Why Recovery Matters More Than You Think(16:17) Kristen's Collegiate Coaching Experience(22:07) What Overworking and Overtraining Looks Like(26:44) Importance of Sleep Consistency(30:17) The HEAL FrameworkSupport the showFollow WHOOP:Sign up for WHOOP Advanced LabsTrial WHOOP for Freewww.whoop.comInstagramTikTokYouTubeXFacebookLinkedInFollow Will Ahmed:InstagramXLinkedInFollow Kristen Holmes:InstagramLinkedInBuy Aligned by Dr. Kristen Holmes: Follow Emily Capodilupo:LinkedIn 

Your smartwatch says you slept great—but you feel exhausted. So who's right: your wearable or your body?We're surrounded by sleep scores, readiness scores, HRV, heart rate, recovery data and stress metrics. But Dr. David Hopper says there's a problem: we may be getting better at reading our devices while getting worse at reading ourselves. In this episode of the Crackin' Backs Podcast, Dr. Hopper joins us to explore how to use wearable technology without becoming controlled—or overwhelmed—by the data.We get into:The one wearable metric Dr. Hopper believes deserves the most attention: HRV Why your sleep or recovery score may disagree with how you actually feel What HRV can tell you about stress, recovery, sleep and your autonomic nervous system Why constantly checking health data may actually create more anxiety How to use an Oura Ring, Apple Watch, WHOOP or other wearable to better understand your body instead of replacing your instincts  The overlooked roles of breathing and sleep in health and recovery  What you might discover if you took your wearable off for an entire week Dr. Hopper explains that HRV can provide useful insight into how the autonomic nervous system is responding to stress and recovery—but emphasizes that wearable data needs context.  His approach starts with something remarkably simple: before checking your watch in the morning, ask yourself how you actually feel. Then use the technology to help confirm and understand those signals rather than dictate them. Because the future of health may not be about collecting more data.It may be about learning which data matters—and knowing when to trust your own body.WATCH TO THE END: Dr. Hopper shares the three things he would teach someone to pay attention to if every wearable disappeared tomorrow.QUESTION FOR YOU: Have you ever felt great—then looked at your watch and suddenly questioned your recovery because of what it told you?

Have you ever noticed how two women fifteen years apart can seem worlds apart in energy, while two women the same age can be aging in completely different directions? In this episode of The Art of Living Well Podcast®, Marnie and Stephanie unpack what they call the midlife health dashboard: the metrics that actually predict how well you're aging, beyond the number on a biological age test. They share their own results from two different biological age tests, including a jarring 16-year gap between the two, and walk through what's actually within your control. Biological age testing has exploded in popularity, with people online sharing scores and spending real money to find out if they're aging faster or slower than their birth certificate says. Marnie and Stephanie have both taken these tests themselves, and they break down what the scores actually mean, what they missed, and why the number matters far less than the daily habits behind it. Whether you've taken a biological age test, are curious about one, or just want a practical way to think about aging well, this episode gives you a place to start today. Key Takeaways: •Biological age tests compare you to other people who took that same test, often a health-conscious group, not the general population •Genetic testing can also reveal your MTHFR status and ApoE genotype, which may be more useful day to day than the biological age score itself •Getting up off the floor without using your hands is one of the simplest predictors of long-term mobility •Walking pace and small daily movement snacks measurably affect how well you age, not just how far you walk •Deep sleep, not just total hours, is one of the most overlooked levers for energy and recovery in midlife •Most women are still under-eating protein, and it shows up in blood work, energy, and cravings •Chronic stress and time spent in fight-or-flight directly affects your biological age, not just how you feel day to day •You don't need a lab test to start improving your health dashboard, an honest self-score across a few key areas is a good place to begin Episode Breakdown with Timestamps: 00:00 Why Two Women 15 Years Apart Can Age So Differently 00:59 Welcome Back: Introducing the Midlife Health Dashboard 01:28 What Biological Age Actually Measures 01:55 Stephanie's Biological Age Test Results, Explained 04:34 Marnie's Two Test Results: One Said 54, One Said 38.6 07:37 The MTHFR Gene and Why Methylation Matters 08:49 Genes Aren't Destiny: A Quick Note on Epigenetics 09:30 Metric: Muscle and Functional Strength 10:21 The "Can You Get Off the Floor" Longevity Test 10:49 Book Rec: The New Fit With Aaron Leventhal (Episode 284) 11:32 Metric: Walking, Movement Snacks, and Pace 13:49 Metric: Sleep and the Midlife Wake-Up Spiral 15:26 Sleep Trackers Worth Trying: Aura Ring vs. Whoop 16:30 Chasing Deep Sleep: What Actually Moved the Needle 17:44 Metric: Stress, the Nervous System, and a PEMF Mat Experiment 19:52 Metric: Protein, and Why Most Women Are Under-Eating It 22:15 Does Everyone Need to Take a Biological Age Test? 23:02 Metric: Connection and Purpose 23:59 Metric: Getting Out of Fight-or-Flight 24:59 Build Your Own Health Dashboard: Score Yourself 25:08 How Old Do You Actually Feel? 28:16 What We'd Tell Our Kids Now 29:21 Share Your Biological Age Results With Us 29:45 Join the Fall Vitality Reboot, Starting September 27 Resources and Links: Episode 267, The New Fit with Aaron Leventhal Episode284 with Danny King (Lifetime) on VO2 max  Episode 319 on Community and Longevity for Midlife Women  Episode317 Design a life you love with the "big ass calendar" co-founder  Feeling tired, inflamed, or stuck in a cycle of cravings? Join our 7-Day Fall Vitality Reboot starting September 27 and discover how much better you can feel with simple daily habits and a supportive community beside you every step of the way.

Andrea Samadi shares her personal resting heart rate data to show why measuring over time matters more than fixating on a single score. She explains how trends reveal stress, recovery, and adaptation, and why comparing yourself to your own baseline is the most useful approach. Learn practical steps to measure consistently, contextualize changes, experiment with one behavior, and use your physiological data to make intentional improvements in sleep, recovery, and performance. BONUS EPISODE 3: ON THIS EPISODE, WE'LL COVER ✔ What resting heart rate can reveal about stress, recovery, and adaptation over time ✔ The story hidden in my own data — from a high of 57 bpm in February to 53 bpm in August ✔ Why the six-month trend matters — and what my 2% lower average may be telling me ✔ How stress and training load can show up in your physiology before you consciously recognize it ✔ Why recovery and nervous-system regulation matter for building a more resilient baseline ✔ How to find your own RHR baseline instead of comparing yourself with someone else ✔ How to look for deviations and patterns across weeks and months—not individual days ✔ How to connect RHR with sleep, HRV, recovery, training, stress, and life events ✔ How to run your own personal experiment: change one variable, measure, and see what happens ✔ The bigger lesson: What gets measured over time can reveal a story you couldn't see day to day. Welcome back to the Neuroscience Meets Social and Emotional Learning Podcast, where we bridge neuroscience, social and emotional learning, and human performance so we can create measurable improvements in our well-being, achievement, leadership, productivity, and results. I'm Andrea Samadi, and if you've been following along through Season 16, you'll know that we've been building what I call The Brain's Operating System for Human Performance—a neuroscience-based framework designed to help us understand how the different systems of the brain and body work together to influence how we learn, adapt, connect, lead, and ultimately how we perform. We are currently in Phase 3 where we are covering Movement, Learning and Cognition. If you just finished Episode 405[i] with Dr. Kristen Holmes, you know we've been looking at recovery as an essential part of our Movement Loop. Movement → Brain Activation → Attention → Learning → Recovery → Adaptation → Performance → Greater Capacity. And Kristen's work has reinforced something I've learned after years of tracking my own physiology: What gets measured gets improved. But this week, I wanted to dive into my own personal data to show us something I think is easy to miss: Sometimes what gets measured over time reveals a story you simply couldn't see day to day. When we're looking at a wearable every morning, it's easy to become focused on today's number. Today's recovery score. Today's HRV. Today's resting heart rate. Was it higher? Was it lower? But one number—or even one week—rarely tells us very much about the direction we're actually moving. It's when we begin to zoom out that patterns emerge. And that's exactly what happened when I looked more closely at my resting heart rate this year. What initially looked like a collection of numbers began to tell a much bigger story about stress, recovery, consistency, and adaptation. So my hope for this episode isn't that you compare your resting heart rate to mine. Your numbers will be different. My hope is that this episode encourages you to become curious about your own data. Maybe you track sleep. Maybe it's HRV. Resting heart rate. Recovery. Exercise. Blood pressure. Steps. Or even something as simple as your energy, mood, or ability to focus. Take one metric and zoom out. Look at three months. Six months. Maybe even a year. And instead of asking, “Is today's number good or bad?” Ask a different question: “What is the trend that I'm seeing here, trying to tell me?” Is something improving? Is something slowly moving in the wrong direction? Does your physiology change during periods of higher stress? (like you will see mine did). Can you see what happens when you sleep more consistently, exercise differently, recover better, or change one habit? Because sometimes the most valuable insight isn't found in today's score. It's hidden in the pattern. And once you can see the pattern, you have information you can actually use. That's really the purpose of sharing my personal data with you today. Not to say, “Here's what worked for me, so you should do exactly the same thing.” But to show you what can happen when we become students of our own physiology. We measure. Find the tool that works best for you. We notice. Patterns…ups and downs. We experiment. We become intentional with our behaviors to change/improve the numbers. We adjust and try something new/different. And then we measure again. Because ultimately, what gets measured gets improved—but what gets measured over time can reveal the story that you tell you more than just a bunch of numbers. And sometimes that story shows us exactly where our next opportunity for change might be. And that's exactly what happened with my resting heart rate. Earlier this year, I watched my monthly average climb to 56...and then 57 beats per minute. You can see my data in the show notes. Sept and October were even, at 54, and then something happened in November that took my RHR up, and it kept climbing.  I know what was happening in those months to cause the increase. And I went all out to protect my recovery. I worked on rest, hydration, extra exercise, and recovery sessions. Then it began coming down. in March 54 in April 53 The 56 in May isn't the most accurate representation of what was happening with my data, as we travelled internationally and there were 5 days my whoop didn't calculate my score correctly (something to do with the change in time zones) so I'm not going to say that I was stressed out during a relaxing vacation. But something happened that caught my attention. You can see it with the graphics in the show notes. My newest six-month WHOOP average dropped from 55 to 54 beats per minute—2% lower than the previous six months. This NEW result was highlighted in GREEN for me to notice the improvement. For the first time in this story, the baseline itself had moved. And that's what we're going to dive into today. Because this episode isn't really about whether 53 is a good resting heart rate. It's about something much more useful: Do you know your baseline with YOUR RHR—and do you know which direction it's moving? Even better, if you can forsee that it will be moving up, like I knew it was going to in January/February, do you have strategies in place to buffer the stress, and keep this number as close as you can to your baseline? Let's dive into this bonus episode. The Story Behind My Resting Heart Rate: Do You Know Yours? There's a number I've been watching for the past year. I watched it raise higher (when I'm stressed) and go lower when I'm doing all the right things to rest and recover. When I zoom out and look at this number over the past year, it tells a fascinating story about my fitness, recovery, stress, and the way my body is adapting. That number is my resting heart rate. And today I want to ask you: Do you know yours? Because one of the biggest lessons I've learned from nearly five years of tracking my physiology is something we've talked about throughout this podcast: What gets measured gets improved. But I think I need to add something to that. What gets measured over time reveals the story. And my newest data makes that clearer than ever. PART 1 — WHAT IS RESTING HEART RATE? Resting heart rate, or RHR, is simply the number of times your heart beats per minute while your body is at rest. Normal Ranges and Fitness[ii] Average adults: 60 to 100 bpm. Active adults: 55 to 85 bpm. Athletes: 40 to 60 bpm, because their heart muscle is strong and pumps blood with ease For adults, resting heart rate varies considerably between individuals. Fitness, genetics, age, sleep, stress, illness, medications, hydration, alcohol, temperature and training load can all influence it. So I'm not interested in comparing my resting heart rate with someone else's. I'm interested in comparing me with me. That's where wearable data becomes useful. Instead of asking: “Is 53 good?” I'm asking: “What is happening to my baseline over time?” And that distinction matters. PART 2 — MY RHR STORY BEGAN WITH A RISE When I first looked at this data, I focused on January and February. My monthly resting heart rate had climbed: January: 56 bpm. February: 57 bpm. Those numbers weren't alarming. I was experiencing higher levels of stress than usual at that time, and I was even prepared for the stress. But relative to my baseline, (55 bpm) the rise caught my attention. And that's an important distinction. A wearable isn't diagnosing why something happened. It can't look at 57 and tell me: “Andrea, this is stress.” But it can show me that something has changed. Then I can look at the rest of my life. How am I sleeping? How am I training? What's my stress level? Am I recovering? What has changed? That's when data becomes feedback. I was ready to implement some stress reduction strategies to get my RHR and nervous system back to its baseline. PART 3 — THEN THE PATTERN CHANGED After February, here's what happened: March: 54. April: 53. May: 56 (International Trip impacted this data) June: 53. July: 55. August: 53. And I love this part of the story because it wasn't a perfectly straight line. My RHR didn't simply go: 57...56...55...54...53. Real physiology rarely works like that. There were fluctuations. May went back to 56. July went to 55. But my resting heart rate kept returning to 53. April: 53. June: 53. August: 53. That's when I began wondering whether I was seeing something more meaningful than a few good months. And now I have another piece of evidence. PART 4 — THE NEW SIX-MONTH RESULT My newest WHOOP six-month report covers February 23 through August 21, 2026. And this is where the story gets interesting. My previous six-month average resting heart rate was: 55 bpm. My newest six-month average is: 54 bpm. WHOOP shows that as: 2% lower than the previous six months. One beat per minute doesn't sound dramatic. But I'm not looking for dramatic. I'm looking for adaptation. Something to show me that my body responded to the extra recovery that I was implementing to buffer the higher stress. For the first time in this particular story, the six-month average itself has moved down. And that means I'm no longer looking only at a few isolated low readings. The trend is beginning to move. PART 5 — THE AVERAGE WAS HIDING THE STORY This may be my favorite lesson from this entire experiment. Earlier, when I looked at a different six-month window, my average RHR was 55 bpm. And the previous six months? Also 55. If I had stopped there, I could have concluded: Nothing changed. But underneath that average was a changing pattern. My RHR had risen to 57 in February. This makes sense to me when I glance at the data. Then it repeatedly returned to 53 with my focus being on rest/recovery. And eventually the rolling six-month average moved from 55 to 54. This is why one measurement rarely tells the whole story. Trends matter. And sometimes your body is changing before the average catches up. PART 6 — 57 TO 53 There's another way to look at the data. February was my highest monthly average in this January–August period: 57 bpm. August is: 53 bpm. That's approximately 7% lower than that February high. I want to be careful with this number because I'm comparing two monthly endpoints—not two six-month averages. So I wouldn't call this a 7% improvement in my overall cardiovascular health. But it is another signal inside the larger pattern. What was happening in February? What is currently happening in August? And when multiple signals begin pointing in the same direction, (showing an improvement) I'm  paying attention. PART 7 — WHAT CHANGED? This is where I think self-experimentation becomes powerful. I didn't respond to the higher numbers by simply exercising harder. I've spent this year becoming much more intentional about recovery and regulation. Sleep. Daily movement. Zone 2 work. Meditation. Hydration. Infrared sauna. Red-light therapy. Paying attention to training strain. And increasingly, listening to what my physiology is telling me instead of automatically pushing through fatigue. I've also been experimenting with removing alcohol at different times this year, and the changes I've seen in recovery, HRV, sleep stress and resting heart rate have given me another variable to continue watching. I can't take this dataset and say: “This one behavior caused my RHR to fall.” There are too many variables. But I can say: The environment surrounding my physiology changed—and my trend changed with it. That's worth paying attention to. PART 8 — WHY DOES A LOWER RHR MATTER? In many people, particularly when associated with aerobic fitness, a lower resting heart rate can reflect a heart that is able to pump blood efficiently with fewer beats at rest. Training can increase stroke volume—the amount of blood pumped with each heartbeat. That means the heart may not need to beat as frequently to deliver the same cardiac output at rest. Autonomic regulation also plays a role. The sympathetic nervous system helps mobilize us for action. The parasympathetic nervous system supports rest-and-recovery processes. Resting heart rate reflects influences from both, along with many other physiological factors. That's why I don't view RHR as a standalone score. I view it as one piece of my physiological dashboard. RHR. HRV. Sleep. Recovery. Training load. And, most importantly: How I actually feel. PART 9 — THIS CONNECTS DIRECTLY TO THE MOVEMENT LOOP Remember the Movement Loop we've been building in Phase 3: Movement → Brain Activation → Attention → Learning → Recovery → Adaptation → Performance → Greater Capacity. My RHR data brings us directly back to the part of the loop I don't want us to overlook: Recovery → Adaptation. Exercise provides the stimulus. But we don't become fitter during the stimulus itself. The body needs an opportunity to respond to that stimulus. To repair. To replenish. To adapt. And eventually, that adaptation may become visible in our trends. That's why recovery isn't the opposite of performance. Recovery is part of the process that makes performance possible. PART 10 — THE BIGGER LESSON This episode isn't really about whether your resting heart rate should be 53. Mine doesn't need to be yours. Your number might be completely different. The question is: Do you know your baseline? And more importantly: Do you know which direction it's moving? What increases it? What decreases it? Because your physiology is constantly responding to the way you're living. Training. Sleeping. Recovering. Working. Traveling. Eating. Drinking. Managing stress. And sometimes those changes are happening quietly beneath the surface. Until you measure them. PART 11 — HOW TO IMPLEMENT THIS IN YOUR OWN LIFE So now I want to turn this over to you. I've shown you my resting heart rate story. What's yours? And you don't need five years of WHOOP data to begin looking for it. You just need enough information to establish your baseline, and then you need to become curious about what causes that baseline to change. Here's how I would start. STEP 1 — FIND A WAY TO MEASURE YOUR RESTING HEART RATE CONSISTENTLY First, find the measurement tool that works for you. Maybe that's WHOOP. Maybe it's an Apple Watch, Garmin, Oura Ring, Fitbit, or another wearable. Or maybe you're tracking your resting heart rate another way. The specific device isn't the most important part of this experiment. You can even just count your pulse beats that you get in one minute while resting. Just stay consistent as you measure. If you're going to look for a trend, you want to compare measurements collected under reasonably consistent conditions. We're not trying to find the lowest number we can possibly produce. We're trying to understand our normal pattern. STEP 2 — LEARN YOUR BASELINE Next, don't start by asking: “Is my resting heart rate good?” Start with: “What is normal for me?” Look at your data over time. If you have it, look at your last month. Then three months. Six months. And eventually a year. What number—or range—does your RHR tend to return to? For me, I knew that my baseline was somewhere around the mid-50s. That's why 56 and 57 caught my attention. Those numbers weren't necessarily concerning when compared with somebody else's resting heart rate. Someone else I know has a RHR of 80 and that's in the normal range. The higher scores mattered to me, because they represented a change from my baseline. That's the first lesson: Compare yourself with yourself. STEP 3 — LOOK FOR THE DEVIATIONS Once you understand your baseline, look for the places where your data moves away from it. Don't immediately label the change as good or bad. Just become curious. When did your RHR rise? When did it fall? Was it one unusual night? Several days? Several weeks? Or did your monthly average actually begin to move? This is where we stop looking at individual dots and begin looking for a pattern. STEP 4 — PUT YOUR LIFE NEXT TO YOUR DATA Now comes the part that I think is the most interesting. Take the RHR graph and mentally place your life beside it. Ask yourself: What was happening here? Was work unusually stressful? Were you traveling? Were you sleeping less? Were you sick? Had your training load increased? Were you drinking more—or less—alcohol? Had you changed your exercise routine? Were you recovering differently? What was happening emotionally? What was happening physically? This was important in interpreting my own data. When I saw my RHR increase in January and February, I knew what was happening in my life during those months. And when I saw May increase, I also had context: I had been traveling internationally, and I knew there were issues with several days of my wearable data. Context changes interpretation. A graph can show you what changed. Your life can help you investigate why. STEP 5 — LOOK AT MORE THAN ONE METRIC Here's another important point. Don't interpret resting heart rate completely by itself. Put it next to other information. What was happening with your HRV? Your sleep? Your recovery? Your training load? Your energy? Your stress? And most importantly: How did you feel? One metric gives us a clue. Multiple signals moving together can give us a much richer picture. Think of it as your own physiological dashboard. You're looking for relationships between the signals rather than allowing one number to define whether you're doing well. STEP 6 — CHOOSE ONE VARIABLE TO EXPERIMENT WITH Now we move from observation to action. Ask: “What is one behavior I could change consistently and then watch what happens?” Maybe it's getting to bed earlier. Maybe it's improving hydration. Adding more Zone 2 exercise. Building recovery days into your training. Meditating. Walking. Changing your alcohol intake. Or simply protecting more downtime during a stressful period. Choose something that's meaningful and realistic for you. Then give it time. This is important because we're not trying to manipulate tomorrow morning's score. We're trying to see whether consistent behavior begins to influence a trend. STEP 7 — MEASURE AGAIN And now we come back to the beginning. Measure. Notice. Experiment. Adjust. And measure again. You might even keep a very simple note beside your data: What changed this month? You could write: Higher workload. Travel. Better sleep. Started Zone 2. Stopped drinking alcohol. Illness. Vacation. More recovery. Over time, you begin creating something much more useful than a collection of numbers. You're creating a map of how your body responds to your life. DISCOVER YOUR RHR STORY So here's the experiment I want to leave you with. Pull up your resting heart rate data. And ask yourself these five questions: What is my baseline? When does my RHR move above or below that baseline? What was happening in my life when it changed? What other physiological signals moved with it? What is one behavior I could intentionally change and measure over time? Then zoom out. Don't judge yourself by tomorrow morning. Look for the story. Because the goal isn't to achieve somebody else's resting heart rate. The goal is to understand your own physiology well enough to recognize when something changes. And then have strategies available to respond. That's where measurement becomes useful. It moves us from simply collecting information... to using information to make better decisions. REVIEW — WHAT DID WE LEARN? Before we close, let's pull everything together. We started with one simple metric: resting heart rate. We learned that RHR tells us how many times our heart beats per minute while we're at rest—but the number becomes much more useful when we stop comparing ourselves with other people and begin comparing ourselves with ourselves. Then we looked at my own story. My RHR rose to: 56 bpm in January. And then: 57 bpm in February. Because I understood what was happening in my life at the time, those increases gave me information I could use. Rather than simply pushing harder, I became increasingly intentional about recovery. Then the pattern began to change. My RHR repeatedly returned toward 53. And eventually something even more interesting happened. My newest six-month average moved from: 55 bpm → 54 bpm. WHOOP identified that as: 2% lower than my previous six-month average. One beat per minute. Not dramatic. But that's exactly the point. We're not looking for dramatic. We're looking for patterns. We're looking for evidence that the system may be adapting over time. And that's why my biggest lesson from this experiment isn't: “My resting heart rate is 53.” It's: “I understand my resting heart rate better than I did before.” I know my baseline. I know some of the circumstances that push it higher. I'm beginning to understand some of the behaviors associated with it moving lower. And most importantly, I know to keep watching the trend. CONCLUSION — BECOME A STUDENT OF YOUR OWN PHYSIOLOGY This brings us back to something Dr. Kristen Holmes reinforced in Episode 405: What gets measured gets improved. But after looking at this data, I want to expand that idea. What gets measured gives us information. What gets measured consistently reveals patterns. And what gets measured over time can reveal a story. That's the opportunity I hope you take away from this episode. Become curious about your own physiology. Not obsessed with it. Not controlled by a score. Curious. Learn your baseline. Notice when something changes. Put that change into the context of your life. Experiment thoughtfully. And then zoom back out and see what happened. Because ultimately, we're not collecting data just to collect more data. We're trying to turn: Data → Awareness → Action → Adaptation. And that brings us right back to our Movement Loop: Movement → Brain Activation → Attention → Learning → Recovery → Adaptation → Performance → Greater Capacity. Your resting heart rate is only one metric. But it gives us a perfect example of what adaptation can look like when we stop staring at today's number and start paying attention to the larger pattern. So sometime after listening to this episode, open your own data. Go back three months. Six months. A year if you can. And ask yourself: “What story has my body been trying to tell me?” You might be surprised by what you find. COMING NEXT — BONUS EPISODE 4 And there's one part of my own physiological dashboard that I deliberately haven't explored deeply today. Sleep. Because recovery doesn't end when we stop exercising. Some of the most important recovery processes happen while we're asleep. So before we return to Dr. John Medina and move deeper into attention, learning, and cognition, I want to stay with the recovery side of our Movement Loop for one more bonus episode. In Bonus Episode 4, we're going to investigate restorative sleep. What exactly is restorative sleep? How can we measure it? What can our sleep data tell us? And perhaps most importantly: How can we use that information to improve the way we recover, adapt, and perform? We'll apply the same approach we used today. Not just: “How did I sleep last night?” But: “What story is my sleep telling me over time?” Because movement creates the stimulus. Recovery creates the opportunity to adapt. And sleep may be one of the most important places where that recovery takes place. I'll see you next time for Bonus Episode 4: The Story Behind My Restorative Sleep.

Drawing on evolutionary biology and the latest research, Dr. Sinclair traces physical activity back millions of years, explaining how humans evolved for endurance, why modern sedentary life creates a profound mismatch with our biology, and how exercise activates ancient cellular pathways involved in repair, resilience, metabolism, and longevity. Dr. Sinclair breaks down what happens inside the body when we exercise, including the molecular responses that help us adapt to stress and influence the brain, immune system, metabolism, cardiovascular health, and even the way our cells age. He also tackles some of the biggest questions in exercise science: Can exercise offset sitting all day? Do we compensate for calories burned during exercise? Why did humans evolve such extraordinary endurance? And could exercising with others provide benefits beyond physical fitness? From our evolutionary past to the molecular machinery inside our cells, this episode reveals why movement is so deeply embedded in human biology – and why staying active may be one of the most powerful ways to keep that biology working as we age. __________________________________________ Partners of the Lifespan show help us keep this program freely available as an educational resource while also supporting medical research.

Send us Fan MailPeaches and Trent sit down with returning guest Marc Esposito and Henry Penix from Soaak for a deep dive into sound frequency compositions, sleep, nervous system regulation, and the future of human performance.Marc explains how retirement led him into the human performance space, working with universities, the military, academia, and industry to help optimize the human weapon system. He also explains why he was initially skeptical of Soaak, why the science started making sense, and why he was willing to put his reputation behind it.Henry breaks down how Soaak uses clinically tested sound frequency compositions instead of generic YouTube frequency tracks. The goal is not magic, not crystals, not woo-woo nonsense — it is using targeted frequencies to help with sleep, anxiety, depression, nervous system reset, low energy, recovery, and performance.The team gets into why sleep is the foundation of human performance, how wearable data from devices like Whoop, Garmin, Oura, Fitbit, Apple Watch, and Samsung Watch can help guide frequency recommendations, and how Soaak is building AI-driven personalized frequency compositions based on what your body is showing in the moment.Marc also talks through his own testing, including using Soaak after brutal threshold work in Texas heat and dropping his heart rate from nearly 190 beats per minute to 80 in about 15 minutes. The conversation also covers stress load, allostatic load, sympathetic and parasympathetic states, PTSD-like symptoms, recovery, family life, and why operators have to learn how to come down after living in fight-or-flight mode for years.This episode is not saying sound frequencies replace hard work. They do not. But if something can help you sleep better, reset faster, recover harder, and show up more functional for your team and your family, that is worth paying attention to.Use code ONESREADY at Soaak.com.Links:- Soaak.com / Promo code: ONESREADY- OnesReady.com- OperatorTrainingSummit.com- ATACLETE / Promo code: ONESREADY- Modern Athlete Strength Systems / Promo code: ONESREADYChapters:00:00 - Intro and Ones Ready01:05 - Soaak Episode Preview02:45 - Marc Esposito and Henry Penix Join03:07 - Marc's Retirement and Human Performance Work05:13 - Why Marc Took Soaak Seriously06:34 - Sound Frequencies Are Not New07:36 - Operators, Sleep, and Coming Down From Fight-or-Flight08:05 - Why White Noise and Apps Matter09:15 - Wearables, Data, and What to Do With It10:17 - Henry's Background and Why Soaak Exists12:46 - From Clinic Modality to Sound Frequency Compositions13:33 - Sympathetic Resonance Explained15:03 - Sleep as Soaak's Most Used Frequency16:02 - Targeting Sleep, Anxiety, Depression, and Reset16:50 - How Frequencies Are Built and Tested20:35 - Why Frequency Effects Make Sense22:06 - Marc's Central Nervous System Reset Testing23:18 - Heart Rate Recovery After Brutal Work24:26 - Performance, Recovery, and Free Chicken25:26 - Hypervigilance, Family Life, and Coming Home Normal27:07 - From 188 Beats Per Minute to 8029:21 - General Minihan and Sleep Efficiency32:33 - Sleep as the Foundation of Performance33:23 - Dual Audio and Listening in the Background35:27 - Getting Frequency Effects Without Extra Equipment37:43 - Military Compliance and Group Use38:23 - Sleep Without More Pills39:43 - Wearable Integration and AI Personalization43:05 - Brain Maps, PTSD, and Long-Term Support43:58 - Neurofeedback-Type Effects46:06 - One Percent Better Adds Up46:49 - Studies, Sleep Records, and Frequency Library49:12 - Stress-Related Doctor Visits49:49 - Epic Fury, Stress, and Mental Health Evacuations51:41 - Readiness, Lethality, and Allostatic Load54:07 - Teaching Young Warfighters to Regulate55:11 - The Rubber Band Stress Analogy57:25 - Frequencies Underwater59:45 - Tinnitus, Earbuds, and Meeting People Where They Are01:01:11 - Soaak Code for Ones Ready Listeners01:02:04 - Use Code ONESREADY01:02:54 - Tinnitus and Frequency Use01:03:38 - Final Links and Wrap-UpSupport the showJoin this channel to get access to perks: HEREBuzzsprout Subscription page:  HERERegister for our Operator Training Summit:  OperatorTrainingSummit.comFind an Air Force Recruiter: AirForce.comCollabs:Ones Ready - OnesReady.com 18A Fitness - Promo Code:  ONESREADY ATACLete - Follow the URL (no promo code):  ATACLeteDanger Close Apparel - Promo Code:  ONESREADYDFND Apparel...

Managing people is a deeply human line of work—it requires relational skills, judgement, and deep knowledge of the people you work with. But Hilary Gridley believes that when used properly, AI can not only help you become a better manager, but can help your team make more meaningful use of their human skills. Hilary has spent years leading teams at companies like Whoop, and she's known for her work helping managers use AI to coach people, give feedback, and develop talent more efficiently. In this episode, Hilary makes the case for why AI belongs in management, and offers practical advice for how to help your team use AI in a way that adds value to their work instead of generating meaningless slop. Hilary and Molly also take a closer look at where many organizations have gone wrong in their adoption of AI tools, and the importance of clarity and communication within a team no matter what technology you have at your disposal.Featured guestFollow Hilary Gridley on X, LinkedIn, and at writerbuilder.com/Subscribe to Hilary's SubstackConnect with the teamFollow Molly on Instagram, LinkedIn, and at glueclub.com/Subscribe to Molly's Substack LessonWatch WorkLife videos on YouTube at TEDPodsFollow TED on X, Instagram, Facebook, LinkedIn, and TikTokFor the full text transcript, visit https://www.ted.com/podcasts/worklife-transcripts Hosted on Acast.
