Welcome to the WHOOP Research Series, where we breakdown into the extensive, scientific research conducted by the WHOOP Performance Science team. On this week's episode, WHOOP Global Head of Human Performance, Principal Scientist, Dr. Kristen Holmes sits down with WHOOP Senior Research Scientist Dr. Greg Grosicki to unpack the latest WHOOP Research Study on Heart Rate Variability Coefficient of Variation or HRV-CV. Using data from 21,000+ WHOOP members and 2 million nights of sleep, Dr. Holmes and Dr. Grosicki reveal why day-to-day stability in your HRV may matter more than the number itself. HRV-CV proves to outperform traditional metrics in detecting the real impact of alcohol, sleep consistency, and metabolic health, making it a great measure of healthspan. By looking deeper into the study, Dr. Holmes and Dr. Grosicki explains how HRV-CV can help you program your training smarter, improve your healthspan and build autonomic resilience. This episode unpacks how measuring HRV-CV isn't just about performance, but risk stratification and understanding your physiology over-time, not just day-to-day. (01:11) Intro To The Study: Why Is HRV-CV Important? (04:09) HRV-CV and Risk Stratification(08:28) Definition of HRV-CV(11:40) What HRV-CV Indicates in Athlete Recovery(14:26) Breaking Down The WHOOP Study(17:13) HRV-CV Trends in Shift Workers(21:21) Why Is HRV-CV an Important Biomarker?(25:18) HRV-CV Trends in Individuals on GLP-1 Medications(26:29) The Weather vs. The Climate: HRV vs. HRV-CV(33:41) The Results: Breaking Down the Data(36:37) How HRV-CV Responds to Certain Behaviors(39:38) Trends Between HRV-CV Between Age, Biological Sex, and Body Mass Index(49:54) How To Improve HRV-CV(56:39) New Research Roles and Opportunities at WHOOPReferences:American Journal of Physiology PublicationHRV-CV: The Key Metric for Lifestyle Consistency and StabilitySupport the showFollow WHOOP: Sign up for WHOOP Advanced Labs Trial WHOOP for Free www.whoop.com Instagram TikTok YouTube X Facebook LinkedIn Follow Will Ahmed: Instagram X LinkedIn Follow Kristen Holmes: Instagram LinkedIn Follow Emily Capodilupo: LinkedIn

I veckans avsnitt dyker vi ner i en ny meta-analys om koffein och fettförbränning – hur stor är effekten egentligen och när märks den? Vi reder ut dosering, intensitet och vad som faktiskt spelar roll för dig som tränar länge. Dessutom svarar vi på lyssnarfrågor om hur du disponerar ett maraton under tre timmar och om puls verkligen är rätt verktyg på tävlingsdagen. Vi pratar också om långpassens längd inför maraton och vad som faktiskt ökar skaderisken.

  In this episode, Freddie and Renee zoom out on the modern wellness landscape—where tech, supplements, scans, and strong opinions are everywhere—and make a case for discernment over dogma. They talk candidly about online criticism, influencer skepticism, and why “trying things” only works when you introduce tools one at a time, track outcomes (HRV, sleep, glucose), and don't confuse information with wisdom. The through-line is simple: foundational health still matters, but intelligent experimentation can be powerful when it's paired with humility and real feedback loops. Then the conversation goes deep into two high-stakes areas people rarely discuss honestly: full-body MRI screening and biological dentistry. Renee shares her Prunuvo experience—how a possible kidney finding triggered weeks of stress and a cascade of follow-up imaging and specialist visits, raising the hard question of where early detection ends and false positives begin. From there, she opens up about a long dental arc that started with a traumatic accident at 16, eventually leading her to remove older titanium implants, manage bone loss and grafting, and transition to zirconia ceramic implants—not as fear-based medicine, but as a “reduce the burden” choice while she explores chronic fatigue, immune markers, and Episode Highlights [00:00] – Renee's Pranuvo full-body MRI experience and the 15mm kidney stone scare [16:02] – False positives, medical rabbit holes, and the emotional/financial cost of early detection [22:53] – Top health yardsticks: glucose markers, HRV, sleep tracking, and foundational labs [25:08] – CGMs, cortisol testing (Dutch & ELi Health), and why trends matter more than single data points [27:15] – Genetic testing, APOE4 status, and using DNA as a focus tool (DNA Company & SelfDecode) [51:37] – Renee's dental trauma story: accident, titanium implants, and root canal decisions [54:56] – Titanium implants, ANA positivity, chronic fatigue, and biocompatibility concerns [59:22] – Surgery recovery protocol: red light therapy, StemRegen, BPC-157 & TB-500 peptides [01:29:10] – Closing reflections and exosome therapy mention   Links & Resources Learn more about Renee Belz → https://reneebelz.com/ Follow Renee on Instagram → https://www.instagram.com/reneebelz/ Listen to the Biohacker Babes: https://podcasts.apple.com/us/podcast/renee-belz-lauren-sambataro/id1470189843 Get Silver Biotics: bit.ly/3JnxyDD — 30% off with Code: BEAUTIFULLYBROKEN Try CatchBio: https://catchbio.com — Code: BEAUTIFULLYBROKEN LightPathLED: https://lightpathled.pxf.io/c/3438432/2059835/25794 — Code: beautifullybroken StemRegen: stemregen.co/products/stemregen?_ef_transaction_id=&oid=1&affid=52 — Code: beautifullybroken   CONNECT WITH FREDDIEWork with Me: https://www.beautifullybroken.world/biological-blueprintWebsite and Store: (http://www.beautifullybroken.world) Instagram: (https://www.instagram.com/freddie.kimmelYouTube: https://www.youtube.com/@beautifullybrokenworld Hosted by Simplecast, an AdsWizz company.

In today's BizNews Premium Editor's Desk, Alec Hogg looks behind the curtain ahead of Budget lock-up — why South Africa's state has become too big, what a shrinking GDP-per-capita scoreboard signals, and what to watch for in the Minister's numbers. He also flags a sobering Financial Times read on Donald Trump's Iran dilemma and the rising risk of conflict, and ends with a practical Economist explainer on HRV — the wearable metric that may be the best indicator of overall health.

What if your hormone imbalance is not just a hormone problem, but a nervous system and emotional overload problem?  In this episode of The Ben Azadi Show, Ben Azadi welcomes back Dr. Sonya Jensen to explore why so many women feel puffy, inflamed, exhausted, and hormonally off even when labs look “normal.” Dr. Jensen connects inflammation, cortisol, progesterone depletion, estrogen dominance, and liver support with the deeper layers most people miss: stress patterns, identity roles, generational stories, and the constant input from news and social media. They also dive into her new book, Heal Your Hormones, Reclaim Yourself, plus practical tools like breathwork, red light, seasonal whole foods, and gentle nervous system regulation. Key Topics Covered Why hormone symptoms can reflect emotional and relational overload Nervous system dysregulation, cortisol, adrenaline, and progesterone depletion How chronic stress can create a bigger estrogen to progesterone imbalance Why blood work can look normal while you still feel off Urine hormone metabolite testing and what it can reveal about detox pathways Breathwork for lowering cortisol and shifting into rest at night Red light as a nervous system tool, especially in the evening Liver support for inflammation and hormone clearance (milk thistle, turmeric) Calming herbs: ashwagandha, lemon balm (Melissa officinalis), skullcap, ziziphus Whole foods and seasonal eating, including “the season of life” concept Movement without overtraining, including walking and habit stacking HRV as a helpful metric, plus the importance of listening to your body How doom scrolling impacts dopamine, oxytocin, and your sense of safety Mitochondria, maternal stress patterns, and inherited nervous system wiring Dopamine as motivation and joy, and oxytocin as bonding and connection Resources Mentioned Dr. Sonya Jensen Website: https://www.drsonyajensen.com/ Instagram: https://www.instagram.com/drsonyajensen/?hl=en Book Heal Your Hormones, Reclaim Yourself: https://healyourhormonesbook.com Follow Ben Azadi

In this episode of the Flex Diet Podcast, I sit down with Denmark-based coach and hybrid athlete Andreas Stobberup to talk about bridging serious strength training with high-level endurance performance. Andreas shares his journey from peaking around 250 lbs with a 405 bench and 600+ squat to dropping to 205 and completing a full Ironman in 9:52—while continuing to coach athletes across disciplines. We discuss the reality gap between amateur and elite performance, how influencer culture often strips context from training advice, and why fundamentals still win: training, nutrition, sleep, and measurable outputs. We break down common misunderstandings around Zone 2 training, why pros don't train the way social media says they do, and how strength athletes can intelligently add conditioning without compromising lifting. We also cover VO₂ max development, microdosing cardio, output-based tracking (times, power, lactate), and how to think about HRV and wearable data in context. If you're interested in hybrid training, improving conditioning without sacrificing muscle, or understanding how to measure what actually matters, this one is packed with practical insight.

View This Week's Show NotesStart Your 7-Day Trial to Mobility CoachJoin Our Free Weekly Newsletter: The AmbushIn a world obsessed with “optimal” routines, Dr. Rachel Pojednic cuts through the noise with a grounded, evidence-based approach to longevity and performance. This conversation is a reset for anyone overwhelmed by conflicting health advice, anxious about wearable scores, or stuck chasing perfect protocols that collapse under real life stress.You'll learn what the science actually supports, what's still uncertain, and how to build a simple, sustainable health strategy using the biggest levers first—movement, nutrition, sleep, stress, and relationships—before you bother with the “fun stuff.” Dr. Pojednic also shares what she's learned studying wellness therapies in industry and academia, why most people misunderstand Zone 2, and what to track if you want a clearer picture of your health over time.What You'll Learn in This EpisodeWhy “protocol life” is making people more confused (and often less healthy)The difference between big levers (high impact) and little levers (fine-tuning) for longevityWhat to track that's actually useful: A1C trends, fasting glucose, lipids, resting heart rateWhy wearable metrics can conflict—and how that can create anxiety and false certaintyA clearer, non-hype explanation of HRV and why “low” isn't always “bad”What Zone 2 is really for (and why it isn't a magical mitochondrial hack)How to think about supplement safety, including third-party testing and the “lead in protein powder” scareA simple 7–30 day “one change” experiment to build habits that survive real lifeIf you've ever felt like you're “failing” health because you can't follow a perfect routine—or you've been pulled in six directions by influencers, devices, and contradictory advice—this episode gives you something rare: a sane framework. You'll walk away with fewer rules, better priorities, and a practical way to measure progress that doesn't depend on hype, fear, or the latest trend.Chapters(00:00) - Intro(01:39) - The Problem with Protocols(05:29) - Rachele's Backstory and Research Journey(13:06) - Rachele's Research Focus(18:45) - Sponsor: Vitality Blueprint(20:40) - Science Communication and Social Media(23:24) - Getting Started in Science Communication(25:10) - Bridging Research and Real-World Applications(29:35) - New Lane for Performance Therapy(31:05) - Key Metrics to Track(32:07) - Importance of Observable, Measurable Data(34:34) - Need for Common Diagnostic Suite(40:19) - Current State of Healthcare and EHRs(42:32) - Momentous: Protein Powder Insights(44:44) - Subscribe to This Podcast(46:30) - Basics We Can All Agree On(47:10) - Regular Tracking Essentials(53:10) - Heart Rate Variability (HRV)(54:42) - Wearables and Big Games(57:06) - Desire to Train(59:28) - Big Opportunity and Challenges(1:00:30) - Rapid Fire: Zone 2(1:03:02) - LMNT: Try a Personal Experiment(1:06:58) - Your Micro-Experiment(1:10:34) - Rachele's “Infinite Shelf” Recommendation(1:14:55) - Join The Starrett SystemWebsite | Instagram | Facebook | YouTubeCheck our Dr. Rachele's courses at Strong ProcessHuge thanks to our sponsors, Vitality, Momentous, and LMNT.

BIA & HRV Explained: The New Way Doctors Are Measuring Healing, Stress & ResilienceWhat if healing didn't have to be based on guesswork?What if you could actually see how your body is responding to stress, detox, nutrition, and emotional regulation—in real time?In this episode of Connecting with the Thom's, we introduce two powerful diagnostic tools that are changing the way health is assessed and supported:BIA (Bioelectrical Impedance Analysis) and HRV (Heart Rate Variability).These tools allow practitioners and individuals to move beyond symptom-based care and into precision, terrain-based medicine—where we measure capacity, resilience, and readiness before pushing the body further.We explore how BIA and HRV help reveal:⚡ Cellular hydration, integrity, and electrical balance

This one stretches the mind in the best way. What if gravity is the most overlooked force in modern medicine? In this episode, we sit down with Dr. Brennan Spiegel, Professor of Medicine and Public Health, Director of Health Services Research at Cedars-Sinai, and Director of the Cedars-Sinai Center for Virtual Medicine and Health System Transformation. We explore bio-gravitational medicine, a groundbreaking framework connecting physics, perception, virtual reality, and human physiology. Watch the video version here. We discuss: How humans evolved to regulate against and stand up to gravity The Reality Paradox and simulation theory in healthcare Why artificial environments may disrupt mind-body balance How virtual reality (VR) can literally "lift" your state of being Why virtual experiences can create real biological change How VR may restore biophilia and reconnect us with our biological origins Why even our perception of gravity influences HRV, cortisol, and mental health What healthcare leaders must consider when designing digital health platforms As digital health accelerates, this conversation challenges us to rethink how technology interacts with human biology. Can simulation realign us with our evolutionary roots? If you're a healthcare executive, clinician, or digital health innovator, this episode will expand how you think about mind-body medicine and the future of healing.

Dr. Mike explains his concept of “human dynamic range” and why the ability to shift gears quickly matters for both performance and health.If you want to build muscle, improve conditioning, and understand how carbs, fasting, and recovery actually fit together, this one's for you!Let's talk about:Introduction to Dr Mike T NelsonCardioMetrics trackingMuscle vs CardioHigh VS Low CarbsLifestyle and Metabolic healthFastingHuman dynamic rangeWhere to find Dr MikeDr. Mike's Newslettter: https://miketnelson.com/ Follow me on Instagram for more information and education:  jeffhoehn_FREE 30 Min Strategy Call: HEREBody Recomp Masterclass: HERENutrition Periodization Masterclass: HEREHow You Can Work With Me?: HERECoaching application: HEREBody Recomp Checklist 2.0: https://chipper-producer-6244.kit.com/26b5c9f94a

Send a textWhen your scope looks great but your day still falls apart, something's missing. We sit down with Dr. Dawn Beaulieu, a Vanderbilt IBD specialist certified in functional medicine, to unpack a root-cause approach that complements biologics and brings relief where patients feel it most: sleep, fatigue, bowel consistency, and energy.We get specific about what functional medicine actually is—science-based, holistic, and individualized—then trace how Dr. Beaulieu integrates it into a busy academic IBD center. From the “functional medicine tree” and Five Rs to team-based care with dietitians and social workers, she shows how nutrition, hydration, and nervous system training shift the gut-brain axis. We talk real-world food strategies that work for sensitive guts, why ultra-processed ingredients and dyes upset the microbiome, and how to ramp fiber without misery. She shares outcomes from Vanderbilt's group programs, where patients improved quality-of-life, sleep, and fatigue in about twelve weeks, with some showing lower fecal calprotectin.We also tackle supplements with nuance: which nutrients many IBD patients actually need, how to choose third‑party tested brands, and why you can't out-supplement a bad diet. Dr. Beaulieu sets clear lines on when medication is essential for moderate to severe disease, then explores where GLP‑1 drugs may help overweight patients alongside standard care. Access matters too, so we highlight ways to find certified functional medicine providers, piece together a local team, and use tools like HRV training and Nerva to build daily resilience.This is a grounded, empowering roadmap for anyone stuck between “remission” and “feeling well.” If the goal is fewer flares and more life, these are the levers you can pull today—without abandoning the therapies that work.

In this deeply grounding and eye-opening episode of the Self-Care Goddess Podcast, I had the absolute pleasure of sitting down with Dr. Torkil Faero to explore the powerful connection between stress, heart rate variability (HRV), resilience, and longevity.Dr. Færø is a Norwegian general practitioner, emergency physician, and author of The Pulse Cure — a transformative book that bridges modern medicine, nervous system wisdom, and wearable technology to help us better understand what our bodies are really telling us.This conversation begins with a gentle HeartMath coherence practice to ground the nervous system and set the tone for a truly integrative discussion. From there, we dive deep into how HRV acts as a real-time window into stress, recovery, inflammation, sleep quality, and overall wellbeing — and how learning to listen to your heart can quite literally change (and extend) your life.We explored how everyday lifestyle choices — from food, alcohol, and sleep, to exercise intensity, sunlight exposure, and even room temperature — impact your nervous system and long-term health. Dr. Færø beautifully explains how tracking HRV can help prevent burnout, chronic fatigue, overtraining, and lifestyle-related disease before the body breaks down.This episode is an invitation to slow down, tune in, and reclaim your power through awareness, data, and compassion for your body.✅What heart rate variability (HRV) really is — and why it matters more than resting heart rate✅How HRV reflects nervous system balance, resilience, and recovery capacity✅Using HRV to detect hidden stressors like food, alcohol, poor sleep, and overtraining✅The powerful connection between breathwork, the vagus nerve, and HRV✅Why quality sleep matters more than quantity — and how HRV reveals true recovery✅Burnout, chronic fatigue, and how HRV can signal trouble months or years in advance✅How diet, inflammation, and ultra-processed foods impact your stress physiology✅HRV, women's health, and understanding stress patterns during the menstrual cycle✅Training smarter — not harder — and avoiding overtraining using HRV feedback✅Cold exposure, heat stress, and optimizing recovery through temperature regulation

Today's guest is Patrick, co-founder of Alveo, a new chest-worn breathing wearable designed to track breath rate variability (BRV) and nervous system state in real time.

Christie Aschwanden is a New York Times bestselling author, former lead science writer at FiveThirtyEight, and one of the sharpest science journalists working today. She's also a former elite Nordic skier for Team Rossignol and a national collegiate cycling champion, so when she set out to investigate the multibillion-dollar recovery industry for her book Good to Go, she brought both a scientist's rigor and an athlete's bullshit detector.  In this episode, Zoë and Brendan talk to Christie about why cold plunges might actually delay your recovery, how your sleep tracker could be making your sleep worse, and why the most effective recovery strategies are boring, cheap, and unsexy. They dig into the rise of the "recovery industrial complex", from Tom Brady's infrared pajamas to cryotherapy chambers that NBA teams bought just because other teams had one, and what the research actually says about inflammation, ibuprofen, HRV, and the post-workout "window" myth. Christie also makes a compelling case for radical acceptance, situational awareness for your body, and trusting your own perceptions over your Garmin readiness score. Plus: the beer mile, knitting as recovery, and why pizza might be the most underrated performance fuel.

In this episode, Dr. Stephen Cabral joins Doug Larson and Dr. Mike Lane to break down how he went from a decade-long "idiopathic illness" in his teens to building one of the biggest health education platforms in the space, including more than 3,600 daily podcast episodes. Cabral shares the turning points in his own recovery: years of heavy antibiotic exposure, chronic stress, gut dysbiosis (candida, H. pylori, SIBO), and even mercury accumulation from frequent tuna intake. That personal case study becomes the foundation for how he now thinks about root-cause medicine versus symptom suppression, and why conventional care often waits until labs fall out of range before acting. The conversation dives into Cabral's framework for how chronic issues typically develop: nervous system stress leads to endocrine disruption, which then cascades into immune dysfunction, often amplified by gut-driven inflammation. He explains a clear process-of-elimination approach to gut health, why bile flow and motility have become increasingly important as the science has evolved, and how stress management is often the missing link. Cabral also breaks down why resonance breathing can be one of the fastest ways to shift physiology, how he uses wearables like Oura and HRV tools without overwhelming clients, and why the best plan is always the one someone will actually follow. Finally, the group zooms out to the future of health and longevity. They discuss biological age testing, emerging longevity research, and the realities of training and recovery as you get older. Cabral shares how his practice balances structured lab testing, repeatable protocols, and ongoing accountability so clients don't just get a plan, but learn how to sustain results long term.

Your heart reveals more about your performance capacity than you think. In this episode of The Game Changing Attorney Podcast, Michael Mogill sits down with Dr. Leah Lagos, clinical psychologist and performance expert, to explore the science of heart rate variability and how a simple breathing practice can transform cognitive performance, emotional regulation, and long-term resilience. From working with elite athletes on the PGA Tour to coaching world leaders and executives, Dr. Lagos breaks down how resonant frequency breathing changes baseline heart rhythms, prevents cognitive fatigue, and allows high performers to make critical decisions without fear. This conversation will equip you with the physiological tools that separate sustained excellence from burnout. Here's what you'll learn: Why heart rate variability is a more reliable indicator of cognitive capacity than most people realize How 15 minutes of resonant frequency breathing twice a day can rewire your nervous system Why comparing your HRV to others is meaningless and what metrics actually matter for performance Want to improve your performance? Start with your heart. ---- Show Notes: 02:58 – Dr. Leah Lagos explains the science of resonant frequency breathing and how it creates homeostasis in the nervous system. 06:20 – Why comparing your HRV to others is meaningless and what metrics actually matter for performance. 12:06 – How chronic stress compounds over time and shows up reliably in your heart rate variability. 13:36 – The lifestyle factors that tank HRV: alcohol, dehydration, excessive caffeine, and who you spend time with. 17:59 – Why HRV training expands prefrontal lobe bandwidth and prevents cognitive fatigue under pressure. 22:35 – How resonant frequency breathing differs from meditation and produces measurable baseline changes in four weeks. 28:45 – The practical protocol: 15 minutes twice a day, finding your resonant frequency, and committing for ten weeks. 37:35 – The role of vagal tone in connecting heart, gut, and brain for better decision-making and health. 39:25 – Why breathwork is a must-have practice for longevity and sustained excellence, not just recovery. ---- Links & Resources: Dr. Leah Lagos Heart Breath Mind by Dr. Leah Lagos Oura Ring WHOOP Garmin Polar Alex Honnold ---- Do you love this podcast and want to see more game changing content?

Episode Highlights With KatieGrounding basics: the Earth is an electron reservoir; skin contact equalizes your body's electrical potential and lowers body voltage.Native vs non-native EMFs: native = Schumann/geomagnetic background; non-native = wiring and wireless sources. Aim to increase exposure to native signals (nature time) and reduce unnecessary non-native exposure, especially during sleep.Physiological effects discussed in studies: improved blood rheology (less RBC clumping), shifts in cortisol rhythm and HRV, reductions in pain and sleep disturbances.Why modern life disrupts it: rubber soles, synthetic floors, and high-rise livingBest outdoor practices: go barefoot on grass/soil/sand (great at sunrise!), beach walks, gardening, sitting on stone/earth, post-flight grounding, leather-soled shoes as a compromise.Moist natural surfaces conduct best.Indoor options and cautions when it comes to grounding mats and sheets.Dirty electricity concern: high-frequency transients on wiring or in soil can ride the ground; test and remediate electrical issues before relying on indoor grounding.Safety notes with thunderstorms or near energized equipment, with implanted electronics or complex medical devices.Start with 20–30 minutes daily outdoors; stack with circadian light (morning sun), movement on natural surfaces, and evening wind-down outsideUse an outlet tester and a body-voltage meter if experimenting indoors.Treat grounding as a low-risk, nature-based habit that pairs well with light, movement, hydration, and mineral balance; consider indoor gadgets optional and proceed only after due diligence.Resources Mentioned EMF canopyGroundies earthing shoesJustine Stenger's Mitochondrial Restoration ProgramDr. Courtney Hunt on Instagram

How does an evaporative cooling vest keep your skin up to 5°C cooler for hours—without making you wet? José Näf shares how smart materials can transform temperature regulation. "Lean more about Nahtlos Duratrode electrodes at https://www.nahtlos.com/" In this episode, Dr. Olli Tikkanen continues the conversation with José Näf, co-founder of Duracool, focusing on the design, functionality, and physiological impact of evaporative cooling vests. These vests use semi-permeable membranes to gradually release water vapor, providing long-lasting cooling without soaking the user. José explains the technical design of their shoulder pads and vests, their application in both occupational settings and for individuals with medical conditions such as artificial menopause, and the importance of wearing them over—not under—clothing. Laboratory tests show their cooling performance lasts significantly longer than sponge-based vests, making them ideal for situations with moderate movement, like construction or low-intensity work in hot environments. This episode is a must-listen for professionals and researchers interested in thermal comfort and performance under heat stress. __________ This podcast episode is sponsored by Fibion Inc. | Better Sleep, Sedentary Behaviour and Physical Activity Research with Less Hassle --- Collect, store and manage SB and PA data easily and remotely - Discover ground-breaking Fibion SENS --- SB and PA measurements, analysis, and feedback made easy.  Learn more about Fibion Research --- Learn more about Fibion Sleep and Fibion Circadian Rhythm Solutions. --- Fibion Kids - Activity tracking designed for children. --- Collect self-report physical activity data easily and cost-effectively with Mimove. --- Explore our Wearables,  Experience sampling method (ESM), Sleep,  Heart rate variability (HRV), Sedentary Behavior and Physical Activity article collections for insights on related articles. --- Refer to our article "Physical Activity and Sedentary Behavior Measurements" for an exploration of active and sedentary lifestyle assessment methods. --- Learn about actigraphy in our guide: Exploring Actigraphy in Scientific Research: A Comprehensive Guide. --- Gain foundational ESM insights with "Introduction to Experience Sampling Method (ESM)" for a comprehensive overview. --- Explore accelerometer use in health research with our article "Measuring Physical Activity and Sedentary Behavior with Accelerometers ". --- For an introduction to the fundamental aspects of HRV, consider revisiting our Ultimate Guide to Heart Rate Variability. --- Follow the podcast on Twitter https://twitter.com/PA_Researcher Follow host Dr Olli Tikkanen on Twitter https://twitter.com/ollitikkanen Follow Fibion on Twitter https://twitter.com/fibion https://www.youtube.com/@PA_Researcher

In this episode of Seat Time, former factory pro and Troll Training coach Alex Martin breaks down why your real gains probably aren't on the track, and how to build the aerobic base, strength, and fueling habits that actually move the needle on race day.We dig into:Why the “ride more” mentality holds most riders back and how periodizing your year (strength, cardio, sprint, technique phases) unlocks real progress.How to honestly identify weaknesses you've been avoiding (starts, sprint speed, technique, fitness) and bake them into your weekly routine without killing the fun.Trusting the bike: understanding setup limits, making smart changes, and taking responsibility instead of blaming suspension, engines, or frames.Arm pump fixes that go beyond gimmicks: strength, aerobic fitness, technique, bike setup, and the mental side of pushing past your usual practice intensity.Alex's “big 5” strength moves for riders (deadlifts, single‑leg work, squats, and key upper‑body presses) and why dumbbells often beat machines.Using wearables (Whoop, Oura, Garmin) and blood work the right way—getting helpful data without letting HRV scores or recovery numbers wreck your head.Practical race‑day and training‑day nutrition: carbs per hour, sodium, training your gut, and simple rules so normal humans can fuel like serious racers.Why investing in quality food, sleep, and long‑term health is one of the most underrated performance upgrades in dirt biking.This is Mindset of the Racer – Episode 2, a 12‑episode 2026 series on the Seat Time podcast feed focused on the mental side of going faster, riding longer, and enjoying dirt bikes more.If this conversation resonates, share it with a riding buddy who takes racing (or themselves) a little too seriously, and make sure you're subscribed so you don't miss the next Mindset of the Racer episode.Sponsor Links:Koch Consulting Firm - Claim Consultants and a Licensed Public AdjusterTwo Sponsor Spots Left (Please reach out)Episode Links:The Ride More MentalityTroll TrainingSeat Time exists to keep you stoked on two wheels!

In this episode, Eric Malzone sits down with industry veteran and Harrison Co. partner Paul Byrne to unpack the "consumer health revolution" transforming fitness, healthcare, and longevity—from GLP‑1s and peptides to wearables, AI "robo docs," and accessible longevity clinics.​ ✨ Key takeaways

Meditation-Induced Changes in High-Frequency Heart Rate Variability Predict Smoking OutcomesDr. Jud explores a pivotal study linking mindfulness meditation and heart rate variability (HRV) to smoking cessation success. This episode delves into how acute changes in high-frequency HRV during meditation correlate with reduced cigarette consumption over time. By examining the physiological underpinnings of self-regulation and addiction, Dr. Jud highlights how HRV may serve as a biomarker to tailor interventions. Tune in to uncover how meditation can reshape the body's stress response and support lasting behavioral change.Reference:Libby DJ, Worhunsky PD, Pilver CE, Brewer JA.

Are you eating clean, training smart, managing stress — maybe even using hormone replacement — but still struggling with fatigue, inflammation, stubborn weight, low energy, or poor recovery?

What does it really take to get healthier with age? In this deeply personal solo episode, mindbodygreen co-founder and co-CEO Jason Wachob shares his N-of-1 longevity experiment—and all the data behind it. At 51 years old, Jason's biological age clocks in at 37.9, with elite cardiovascular and recovery metrics to match: a VO₂ max of 52, resting heart rate as low as 35, and record-high HRV. This isn't about extreme biohacking or million-dollar longevity protocols. Jason breaks down the exact lifestyle choices, training approach, and precision nutrition strategies that helped him reverse key aging markers—while balancing life as a CEO, husband, and father of two. He also opens up about the emotional weight of outliving multiple generations of men in his family—and why, for him, longevity is ultimately about presence, strength, and showing up fully for the people he loves. Whether you're curious about VO₂ max training, heart rate variability, diet personalization, or how to build sustainable habits without burning out, this episode offers a rare, data-backed look at what's possible with consistency and intention.

Cold plunges are everywhere, and the way people talk about them, you'd think they're a miracle cure for your brain, body, and soul. But in an age of algorithm-fueled evangelism, when a ritual becomes this ubiquitous and loud, we have to ask: how much of the buzz is backed by science… and how much is just marketing? In this episode, we explore the neuroscience of cold exposure: what's real, what's overstated, and why this "discomfort" has become a billion-dollar industry. We discuss: Why cold plunges went viral, and how wellness movements often devolve into identity-driven cultures The difference between cold exposure itself and the monetized "cold plunge movement" What constitutes a "cult" (and how pseudoscience forms around partial truths) The real physiological cold shock response Why the mental "high" after a plunge doesn't automatically equal long-term brain benefit The cardiovascular risks that rarely get discussed, especially for people with underlying heart disease What the research suggests about soreness, pain reduction, and muscle growth (including why cold immersion can blunt hypertrophy) The real story behind brown fat Who should avoid cold plunges altogether (asthma, arrhythmias, coronary disease, vascular conditions) Joining us for this conversation is investigative journalist and bestselling author Scott Carney (What Doesn't Kill Us, The Wedge), who has spent years inside the cold exposure world, first as a skeptic, then as a believer, and eventually as a critic of the culture that formed around it. His work reveals what happens when discomfort becomes identity, and when unfounded "social media science" outruns real science.

When it comes to longevity, most of the research feels clear around exercise and nutrition. We know how they affect aging and the prevention of the four diseases that kill most people: heart disease, cancer, metabolic disease, and dementia. But where do sleep, stress, and lifestyle actually fit into that picture?  In Part 1 of the 2026 Body Blueprint, Ted explained why most men over 40 age faster than they should.   In Part 2, he broke down why weight loss alone doesn't equal health.   In Part 3, he showed how men should train to preserve muscle and strength with minimal time.   In Part 4, he explained why cardio and cardiovascular fitness are essential for longevity—even if you already lift.   In Part 5, he shared a clear, evidence-based approach to nutrition that supports metabolic health, longevity, and fat loss without quitting your social life or eliminating foods you enjoy.  In Part 6, Ted turns to the most underestimated drivers of how you age: sleep, stress, and lifestyle. He explains why these factors are harder to quantify but just as powerful, how they quietly influence disease risk and recovery, and why ignoring them can undermine even the best training and nutrition plan. This episode puts the final pieces of the longevity puzzle into place.  You'll learn:    How poor sleep drives fat gain, insulin resistance, and hormonal decline  The surprising link between sleep, pain sensitivity, and chronic injuries  How chronic stress accelerates aging even in mentally tough high achievers  Objective ways to measure stress using heart rate, HRV, and blood pressure  The difference between managing stress symptoms vs. fixing root causes    What Ted discusses in this episode:  (00:00) Introduction (04:35) The Importance of Sleep for Longevity (08:42) Hormones and Sleep (16:42) Sleep Hygiene Tips (24:52) The Role of Caffeine and Alcohol in Sleep (29:35) Understanding and Managing Stress (30:08) Understanding Chronic Stress (30:42) The Importance of Recovery (32:07) Defining Stress and Its Effects (35:13) Tracking Stress with Biomarkers (40:08) Strategies for Managing Stress (47:05) The Power of Social Connections (53:12) Conclusion and Final Thoughts

You don't rise to your potential—you recover to it. Sleep isn't a luxury. It's a skill. On this episode of WINNERS FIND A WAY, Trent M. Clark sits down with Mollie Eastman, founder of Sleep Is a Skill and host of one of the top sleep podcasts in the world, to tackle one of the most overlooked performance levers in leadership, entrepreneurship, and elite athletics: sleep and recovery. From HRV and wearables to circadian rhythm, wake-ups at 3am, sleep anxiety, and data overload, this is a masterclass in how top performers actually win—by mastering the downshift. This conversation isn't theory. It's practical, real-world, and immediately actionable. About the Guest Mollie Eastman is a leading voice in sleep optimization, founder of SleepIsASkill.com, and creator of the Sleep Obsessions newsletter. She works with entrepreneurs, Special Forces operators, high-stakes performers, and professional athletes to transform sleep from a liability into a competitive advantage. Her work bridges cutting-edge science with practical implementation—without fragility, gimmicks, or excuses. Key Topics Covered Why sleep is a trainable skill, not a genetic sentence The difference between stress vs. distress in performance HRV, wearables, and when data helps—or hurts The real reasons people wake up at 3–4am Circadian rhythm > night routines alone Why elite performers must master day mode vs. night mode How leaders unknowingly model poor recovery for their teams Resources Mentioned Sleep Is a Skill – https://sleepisaskill.com Sleep Obsessions Newsletter Books: The Power of the Downstate Mind After Midnight The Upside of Stress Tools & Concepts: HRV Tracking Oura Ring / WHOOP Circadian Rhythm Intermittent Fasting CBT-I & ACT-I approaches to insomnia

Note: This episode was originally recorded and first released on June 27, 2024. We're resurfacing it because the conversation is more relevant than ever, and the insights remain as timely today as they were when first published. Your heart doesn't beat like a metronome, and that variability between beats reveals everything about your body's ability to handle modern stress. I get tons of questions about HRV, and here's what you need to understand: HRV measures the balance between your sympathetic nervous system (fight-or-flight) and parasympathetic nervous system (rest-digest), and research published in Frontiers in Neuroscience shows it's a powerful non-invasive biomarker linked to mental and physical health.
