View This Week's Show NotesStart Your 7-Day Trial to Mobility CoachJoin Our Free Weekly Newsletter: The AmbushWhat if the fitness metrics you're obsessing over aren't telling you what you think they are? HRV. VO2 max. Resting heart rate. Zone 2. Wearables have given us more data than ever… but do you know how to use it to inform your training?In this episode of the Ready State Podcast, Kelly and Juliet Starrett sit down with renowned strength and conditioning coach Joel Jamieson to cut through the noise around cardiovascular fitness, recovery, and resilience. Drawing on more than 25 years of experience coaching UFC champions, Olympic athletes, special operators, and professional sports teams, Joel explains why a higher HRV isn't always “better,” what Zone 2 training is really trying to accomplish, and why your aerobic engine matters even if endurance sports aren't your thing.They also explore how to balance low, moderate, and high-intensity training, practical ways to measure whether your conditioning is actually improving, and why stress outside the gym has to factor into how you train. The takeaway? Better fitness isn't about chasing a perfect score – but about understanding what your body can handle, how well it recovers, and how to train accordingly.What You'll Learn in This EpisodeWhy a higher HRV doesn't always mean you're better recoveredWhat Zone 2 training is actually trying to accomplishWhy cardiovascular fitness is important for improving resilienceHow to balance low, moderate, & high-intensity conditioningWhy stress outside the gym should influence how you trainKey Highlights: (00:00) Intro: Joel Jamieson on HRV & Conditioning(03:33) The HRV Problem for Midlife Athletes(05:13) What Is HRV?(09:41) The Evolution of HRV Tracking(13:32) What's a Good HRV?(16:18) Morning vs Overnight HRV(20:49) Why Higher HRV Isn't Always Better(24:00) HRV, Resting Heart Rate, & Heart Rate Recovery(26:50) Chest Strap vs Wrist-Based HRV(29:33) How to Improve Your HRV(34:10) How Fast Cardiovascular Fitness Declines(37:53) Training Intensity Zones Explained(43:30) Low, Moderate, & High Intensity Training(45:59) Why Low-Intensity Training Builds VO2 Max(48:33) Is VO2 Max Testing Worth It?(51:04) The Cooper's Test(55:09) How Fast Can Conditioning Improve?(59:55) Team Athletes & Recovery(1:01:46) Life Stress, HRV, & Training(1:04:00) Lifestyle Sets Your Gym Limits(1:05:21) Infinite ShelfHuge thanks to our sponsors,Momentous, LMNT, and BEDGEAR.

Dr. Martin Gibala is a Professor of Kinesiology at McMaster University and one of the world's leading researchers on high-intensity interval training.Can short bursts of hard cardio outperform hours of Zone 2 for the average person? Exercise physiologist Dr. Martin Gibala explains how HIIT can improve VO2 max and metabolic flexibility, why elite athletes' 80/20 split may not fit a time-strapped schedule, and how to judge vigorous effort without chasing a perfect heart-rate zone.Expect to learn how to scale HIIT for beginners, what RPE and the talk test reveal about vigorous effort, when short sprints differ from VO2 max intervals, why elite athletes' 80/20 approach may not fit your schedule, how Zone 2 definitions can mislead, and what metabolic flexibility and mitochondrial capacity really mean—and much more.Connect with Martin:Website: martingibala.comX: @gibalamBook: The One-Minute Workout (Avery, 2017; with Christopher Shulgan)Podcast: Exercise ScienceEpisodes you'll enjoy next:#402 — VO2 Max, Zone 2 Training & the Psychology of Human Performance — Ben Skutnik: Dr. Ben Skutnik cuts through Zone 2 hype and discusses VO2 max and aerobic-training evidence.#387 — Nathan T.

My VO2 max dropped 25% in five years. It fell from 46.5 down to 34.7 by age 42. Then I got it back up to 41.4 at 45. In this video, I break down exactly what VO2 max is, the science-backed VO2 max training protocols proven to increase it (on a treadmill, a bike, and with kettlebells), how to track your VO2 max on an Apple Watch or Garmin, and the VO2 max chart by age and gender so you know exactly where you stand. VO2 max is your body's engine size. It's the most oxygen your body can use when you're working hard, and research shows it's one of the strongest predictors of how long, and how well, you'll live. The best part? You can improve it at any age. ► Free 7 Day Trial To My Workout App: https://www.liveleantv.com ► Live Lean Body Quiz: https://www.liveleantv.com/quiz ► Free 7 Day Meal Plan And Recipes: https://www.liveleantv.com/free-stuff ⏱ TIMESTAMPS 00:00 My VO2 max dropped 25% 00:59 VO2 Max Explained 02:14 VO2 Max Training 03:19 VO2 Max Workout vs. HIIT Workouts 04:32 Norwegian 4x4 Interval Training Workout 05:54 VO2 Max Cycling / Stationary Bike Workout 06:50 VO2 Max Kettlebell Workout Exercises 08:34 VO2 Max On Apple Watch And Garmin 10:18 VO2 Max Test: Treadmill vs. Cycling 11:11 VO2 Max Chart By Age And Gender 11:58 VO2 Max Ranges To Aim For 12:52 Your Game Plan To Increase VO2 Max

Enten du har lest saker om løping på Aftenbladet.no, eller skummet gjennom toppen av resultatlister fra lokale mosjonsløp, har du nok sett navnet hans før.En råsterk løper, og en enda sterkere journalist.Nysgjerrighet, lidenskapelig og spørrende er kvaliteter man kommer langt med i mange yrker, og det merkes i sakene Tom Gøran skriver at han har det i hopetall.De siste årene har han samtidig hatt en ganske unik utsikt til det som har skjedd med løpingen i Rogaland. Han har skrevet om den, intervjuet menneskene i den og stått på startstreken midt i den selv.Vi snakker om utviklingen Tom Gøran har vært vitne til, menneskene som nå finner veien til startstreken, løpeklubbenes betydning, journalistikk, fellesskap og hvorfor historier om helt vanlige mosjonister kan være langt mer interessante enn tiden de løper på.Takk for praten, Tom Gøran.

Dit is de 280e aflevering van de Slimmer Presteren Podcast, over sport, onderzoek en innovatie. In deze aflevering hebben Gerrit Heijkoop, Jurgen van Teeffelen en Guido Vroemen het over:Lactaatgel: helpt lactaat slikken je echt harder te gaan?INLEIDING:Lactaat was jarenlang de stof waar je als sporter juist vanaf wilde. Nu zit het in een gel die profs in de Tour gebruiken, en die je gewoon zelf kunt bestellen. Werkt zo'n lactaatgel echt, of koop je vooral een duur verhaal? Gerrit Heijkoop en Jurgen van Teeffelen proeven hem live, met sportarts en topcoach Guido Vroemen erbij vanaf de eerste minuut. Guido testte de gels bij een aantal van zijn eigen atleten en vertelt wat hij daar wel en niet uit kan afleiden. In deze aflevering:- waarom lactaat geen afvalstof is maar brandstof voor spier, hart en hersenen- hoe extra lactaat je eigen glycogeenvoorraad zou kunnen sparen- waarom het dertig jaar lang niet lukte om lactaat behapbaar te krijgen- wat de studies laten zien: wel een lichter gevoel, geen snellere tijden- het verschil tussen ExoLactate en de lactaatgel van Enervit- wanneer je zo'n gel zou innemen, en waarom niet bij de start- waarom een goede eigen ervaring nog geen bewijs is Vragen die in deze aflevering worden beantwoord: 1. Wat zit er in een lactaatgel en wat is het idee erachter?Een lactaatgel combineert lactaat met gewone koolhydraten. Het bekendste voorbeeld, ExoLactate van From Lab to Field, bevat 5 gram lactaat en 40 gram koolhydraten per gel. Het idee erachter is dat lactaat geen afvalproduct is, maar een brandstof die spieren, hart en hersenen kunnen verbranden. Volgens Guido Vroemen levert lactaat van buitenaf een tweede energiebron, waardoor je je eigen glycogeenvoorraad langer intact houdt tijdens intensieve inspanning. Bewijs voor dat mechanisme bij sporters ontbreekt vooralsnog.2. Waarom werd lactaat lang gezien als afvalstof en nu als brandstof?Lactaat stijgt in je bloed bij zware inspanning, en dat leidde decennialang tot de conclusie dat het de oorzaak was van vermoeide, verzuurde benen. Hoogleraar George Brooks van University of California, Berkeley betoogt al veertig jaar het omgekeerde. Lactaat ontstaat continu in de glycolyse en wordt door spieren, hart en hersenen als brandstof gebruikt. Daarnaast werkt het als signaalstof. Dat lactaat de grens van je prestatie markeert klopt nog steeds, maar als graadmeter, niet als oorzaak.3. Waarom lukte het dertig jaar lang niet om lactaat als sportvoeding te gebruiken?Het probleem was nooit de theorie, maar de praktijk. Om effect te mogen verwachten moet je een flinke dosis binnenkrijgen, en dat lukte niet. Lactaat werd meestal aan natrium gebonden, waardoor sporters last kregen van hun maag. In een onderzoek uit 2024 dronken vijf deelnemers natriumlactaat, waarna hun bloedlactaat niet steeg terwijl er wel matige tot ernstige maagdarmklachten optraden. Guido Vroemen probeerde het jaren geleden zelf, en door de pH-waarden kwam het net zo hard weer omhoog.4. Wat laat het onderzoek naar exogeen lactaat zien over prestatieverbetering?De uitkomsten zijn opvallend eenzijdig. Bij zestien getrainde wielrenners steeg na inname van lactaat het bicarbonaat en daalde de ervaren inspanning meetbaar, maar werden de tijden geen seconde beter. Een pilotstudie bij vijftien recreatieve sporters vond geen effect op VO2max, ventilatoire drempel of lactaatdrempel, wel een klein positief effect op het vermogen in een tijdrit van twintig minuten. Jurgen van Teeffelen wijst erop dat nog geen enkele studie laat zien dat dit lactaat werkelijk in het bloed en in de spier terechtkomt.5. Wanneer kun je een lactaatgel het beste innemen tijdens een wedstrijd?Niet aan de start, want dan heb je nog geen tekort aan glycogeen. Guido Vroemen ziet de meeste waarde in de finale: aan het eind van het fietsen, bij de overgang naar het lopen, of in de laatste kilometers van een loop. Volgens de makers wordt dit lactaat sneller opgenomen dan glucose en fructose, binnen vijf tot tien minuten, dus ver vooruit plannen hoeft niet. Zijn praktische tip is om er één apart te houden met “finale” erop.6. Welke nadelen heeft een lactaatgel voor de recreatieve sporter?Het grootste bezwaar is de prijs. Een gel kost ongeveer vijf euro, verzendkosten nog niet meegerekend, terwijl er 40 gram gewone koolhydraten in zit die je veel goedkoper krijgt. Daarnaast is de textuur dikker en slijmeriger dan bij een gewone gel, dus een slok water erachteraan is nodig. Maagdarmklachten meldden de testers niet. Het echte nadeel is dat het bewijs ontbreekt: je betaalt voor een mechanisme dat bij sporters nog niet is aangetoond.Handige bronnen en links:Alle shownotes, bronnen en links bij deze aflevering:https://slimmer-presteren-podcast.nl/seizoen-14/280-lactaatgel-zinvol-of-onzin/ Achtergrondartikel over hoe lactaatgels in het wielerpeloton verschenen:https://www.cyclist.co.uk/in-depth/lactate-gels Studie uit 2024 waarin oraal natriumlactaat het bloedlactaat niet verhoogde:https://pubmed.ncbi.nlm.nih.gov/39262340/ Studie uit 2024 met een lagere ervaren inspanning maar geen prestatiewinst:https://pubmed.ncbi.nlm.nih.gov/39189224/ Eerdere aflevering over lactaat als wonderstof:https://slimmer-presteren-podcast.nl/seizoen-7/128-lang-leve-lactaat-de-wonderstof-om-slimmer-te-presteren/ Eerdere aflevering over bicarbonaat als buffer tegen verzuring:https://slimmer-presteren-podcast.nl/seizoen-3/helpt-extra-bicarbonaat-de-sportprestatie/ Abonneer je op dit kanaal voor iedere vrijdag een nieuwe aflevering over sport, onderzoek en innovatie.

Full show notes: BenGreenfieldLife.com/506 In this episode, you'll discover three things I've been asked about constantly: whether the melatonin heart failure headline is worth worrying about, how much sleep is actually too much or too little, and the shortest route to a higher VO2 max. I break down what the melatonin study did and did not reveal, why a key prescription detail changes how the findings should be interpreted, and why I still use high-dose melatonin for jet lag. Then I move to VO2 max, including the Norwegian 4x4 explained the way I used to coach it, what the sprint interval research says about doing it faster, and the tools that work beyond exercise, from heat acclimation to altitude to correcting an iron deficiency. You'll also hear what a new Nature study of half a million people found about the 6.4 to 7.8 hour sleep window, and why I still sleep less than that on purpose. Finally, fertility for men and women. On the male side, scrotal temperature, timing intercourse around ovulation, the lubricant problem nobody mentions, and the supplements with real human data behind them, from L-carnitine and CoQ10 to zinc and shilajit (use code GREENFIELD for free shipping). On the female side, ovulation tracking, acupuncture, CoQ10 before egg retrieval, and inositol. Plus how to preserve fertility if you're on testosterone replacement therapy (TRT).

If you're a woman in perimenopause or postmenopause, you've probably seen the claim that running is bad for your hormones because it raises cortisol. Maybe you've even wondered if you should be doing less cardio, switching entirely to walking, or giving up running altogether.In this episode, Kevin and I unpack that idea and talk about what cortisol actually does in the body. Yes, exercise temporarily raises cortisol, but that's a normal and useful response. The bigger issue is chronic stress, poor sleep, under-fueling, and inadequate recovery. And while menopause can change how our bodies respond to stress, that doesn't mean we need to stop doing something that's incredibly valuable for our cardiovascular health, fitness, and brain health.I want you to walk away from this conversation feeling less afraid of running and more confident about how to balance running, strength training, fueling, recovery, and the rest of your life.00:00 – The Menopause Running Myth02:50 – Where the Claim Comes From07:08 – Cortisol Isn't the Villain11:08 – Menopause and Cortisol Regulation13:41 – What Actually Drives High Cortisol15:20 – Research Says Aerobic Exercise Helps18:11 – The Real Risk Is Heart Health21:35 – Why Walking Isn't Enough25:09 – VO2 Max and Longevity29:03 – Measuring VO2 Max33:01 – Training to Boost VO234:16 – Brain Benefits of Cardio38:44 – Cortisol Fearmongering40:24 – Strength Plus Running43:11 – Walking Versus Aerobic ExerciseGain access to my new secret podcast, Unbreakable: The Runner's Guide To Injury-Proofing Your Body After 40.

Send us Fan MailWhat if building muscle isn't just about looking better—but about living longer, staying independent, and maintaining your health as you age?In this episode of the Fit Rx Health & Wellness Podcast, Dr. Greg Dennis continues the 7 Pillars of Optimal Health series with Pillar #3: Movement & Strength.Exercise has been a major part of Dr. Dennis's life for more than 30 years, but the reasons for exercising have changed. What may start as a desire to build muscle or improve appearance becomes something much more important as we age: preserving strength, metabolic health, mobility, and the ability to keep doing the things we love.In this episode, Dr. Dennis discusses:Why skeletal muscle can be thought of as an organ of longevityThe powerful relationship between physical fitness and lifespanHow muscle helps regulate blood sugar and improve insulin sensitivityWhy maintaining muscle becomes increasingly important as we ageThe connection between strength training, bone health, mobility, and independenceWhy simply walking is important—but isn't a complete exercise programHow often you should strength trainWhat progressive overload means and why it mattersWhy cardiovascular fitness is just as important as strengthWhat Zone 2 cardio is and how to incorporate itWhat VO₂ max measures and why it's such an important marker of longevityHow high-intensity intervals such as the Norwegian 4x4 can improve aerobic fitnessHow to balance strength training, Zone 2 cardio, and VO₂-max trainingDr. Dennis's own weekly exercise routine and how he approaches training for both muscle and longevityYou don't have to become a bodybuilder or an endurance athlete to benefit from exercise. The goal is to move every day, build and preserve muscle, and develop the cardiovascular fitness necessary to remain capable throughout life.Muscle isn't just about appearance. Muscle is freedom. It helps preserve your ability to work, travel, climb stairs, carry groceries, play with your children or grandchildren, recover from illness, and maintain independence as you age.Don't just exercise to weigh less. Train for the life you want to be capable of living.This is the third episode in the 7 Pillars of Optimal Health series from the Fit Rx Health & Wellness Podcast.Support the show

In today's Research Roundup we bring you four recent studies. How world-class Norwegian endurance coaches programme strength and speed, the factors determining how a runner's physiology holds up over two and a half hours of running, a defence of the critical power model written by the people who built it, and a polarised versus high-intensity trial in cyclists with a result neither of us expected.HIGHLIGHTS AND KEY TOPICS:Strength and speed training across eight Olympic endurance sports (including triathlon, swimming, cycling and running), from 12 world-class Norwegian coaches whose athletes have won over 400 international medals. How many hours a year each sport does, and which sport sits at the bottom of the table.What those sessions look like: exercises, sets, reps and how close to failure the athletes are taken, which is a long way from what randomised trials prescribe. Plus the 10 hours a year of speed training every sport did, and what it looks like.How Daniel and Mikael each place strength and speed work in a real training week, where they differ from the Norwegian model, and why an age-group athlete in their forties is a different case from an Olympic athlete in their twenties.Physiological resilience (durability) during two and a half hours of continuous unfed running, with thresholds, running economy and VO2max retested at the end. Which variables fall most, which barely move, and how runners of different ability differ.Mikael sets the running economy decline against what a pair of carbon shoes buys you and asks which is bigger. Plus the two qualities that separated the runners who held up, one aerobic and one from the gym.Ten common criticisms of the critical power model, answered by the group that built it: whether CP is just FTP renamed, whether the model claims you can hold CP forever, whether a power law fits the curve better, and where the authors concede most.Critical power as a moving number rather than a fixed one, what that does to how you prescribe a threshold session, and the gap between the test durations the paper recommends and the ones Mikael actually uses.Polarised against high intensity with the hard sessions held identical, three a week for six weeks, one group adding four hours a week of easy riding. What the time trial showed, and why Mikael thinks the result is wrong (a strong statement!).SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:Follow Daniel Rowland and Endurance Ideas and Implementation on his website, Substack and Instagram.The shownotes for today's episode can be found here.The full podcast episode archives (including category filters) can be found here.Related episodes:New Research on Torque Training, Ketones, Carb Loading and Pacing | Daniel Rowland | EP#698The 10% Rule Applies to Your Long Run, Not Your Week | Research Roundup | EP#709Is VO2max more important than lactate threshold? | Research roundup | EP#705[Triathlon Science] Durability decoded – a 2025 perspective with Michele Zanini, PhDStudies discussed:Strength and Speed Training Practices for Olympic Endurance Sports: Insights From World-Class Coaches - Haugen et al. 2026Determinants of Physiological Resilience Among Recreational-To-Competitive Endurance Runners - Malinen et al. 2026Ten Common Criticisms of the Critical Power Model Revisited - Black et al. 2026The effectiveness of polarized versus high-intensity training in moderately trained cyclists: a randomized parallel-design study - Moran-MacDonald et al. 2026Best-Practice Training Characteristics Within Olympic Endurance Sports as Described by Norwegian World-Class Coaches - Sandbakk et al. 2025Strength Training Improves Running Economy Durability and Fatigued High-Intensity Performance in Well-Trained Male Runners: A Randomized Control Trial - Zanini et al. 2025Effects of Exercise Training on Mitochondrial and Capillary Growth in Human Skeletal Muscle: A Systematic Review and Meta-Regression - Mølmen et al. 2024 SPONSORS: Precision Fuel & Hydration produce our favourite gels, sports drinks, and electrolyte and carbohydrate products here at That Triathlon Show and Scientific Triathlon.

Have you ever looked at your schedule and thought, “I only have 20 minutes, so it's not even worth running”? I get it. As runners, we can easily fall into the trap of believing that a run only counts if it's long enough, fast enough, or fits perfectly into our training plan. But in this episode, Kevin and I are kicking off a new series where we bust some of those common running myths, starting with the idea that short runs aren't worth it.I actually got a real-life reminder of this when a few short 20-minute run/walks with our rescue dog, Jasper, ended up having more of an impact on my training than I expected. It made me think about how often we dismiss the training we can do because it doesn't look like the training we think we should be doing. We talk about the mindset traps behind this, including all-or-nothing thinking, comparison, productivity, and even the hassle of showering and doing more laundry.We also dig into what the research tells us about maintaining fitness when you have less time to train. The goal isn't to turn every short run into a hard effort. It's to understand that shorter runs can still provide a meaningful stimulus, and sometimes a little running is much more valuable than skipping it altogether.01:37 – Why We're Busting Running Myths02:28 – Are Short Runs Actually Worth It?03:56 – My Short Runs With Jasper07:17 – What My Garmin Data Taught Me10:00 – Why Running Isn't the Same as Walking13:23 – The All-or-Nothing Trap16:54 – When Showering and Laundry Become the Barrier18:12 – Consistency Over Distance19:45 – Can Long Runs Increase Injury Risk?20:59 – What the Research Actually Says23:19 – What the Hickson Study Says About Frequency25:39 – What Happens When You Reduce Duration?26:56 – Why Intensity Still Matters30:00 – How to Add Intensity When Time Is Short31:04 – Short Runs Still Count32:12 – The Jasper PrincipleGain access to my new secret podcast, Unbreakable: The Runner's Guide To Injury-Proofing Your Body After 40.

« Ça fait mal aux genoux. » « C'est trop intense pour le cœur. » « Tu as vu, il y a encore eu un mort sur une course ce week-end. » Tu as sûrement déjà entendu ce genre de phrases dès que tu parles d'accélérer après 40 ans. Guillaume, lui, se les prend dans son entourage et se demande s'il doit arrêter le fractionné en vieillissant. Dans cet épisode, je te donne les vrais chiffres et surtout la bonne manière de continuer à accélérer, même après 50 ans, sans te mettre en danger.Liens :Gratuit : le guide de la sortie longue : https://go.soulier.xyz/sortielonguekm42Le Protocole Perte de Gras : https://go.soulier.xyz/protocolekm42Rejoindre le Hamsters Running Club : https://km42.soulier.xyz/hrcTous les liens vers les anciens épisodes : https://km42.soulier.xyz/467Posez vos questions : https://go.soulier.xyz/faqLe fractionné, un truc de jeunes ou de coureurs pointus ? C'est la première réaction, passé la quarantaine : la méfiance. Et pourtant les études disent l'inverse. Une revue systématique portant sur près de 1800 participants de 60 ans et plus montre que l'entraînement à haute intensité est une des approches les plus efficaces pour la santé, comparée à l'absence d'exercice ou à d'autres formes d'entraînement. Une autre étude, sur des sexagénaires et septuagénaires non sportifs au départ, montre des gains de 15 à 20% de VO2max, 12% de force musculaire et jusqu'à 15% de fonction cognitive après un programme adapté.Mais il y a un piège dans ce raisonnement, et c'est là que je voulais aller plus loin. Ce que le fractionné sollicite précisément, ce sont les fibres musculaires rapides, celles qui s'effondrent le plus vite avec l'âge à cause de la sarcopénie. Résultat : arrêter le fractionné après 40 ou 50 ans, c'est accélérer cette perte plutôt que la freiner. Mais ce n'est pas non plus un blanc-seing pour foncer tête baissée, parce que le fractionné reste l'exercice le plus traumatisant pour l'organisme d'un coureur, et la réparation prend plus de temps avec l'âge.Dans cet épisode je te donne les vrais leviers pour continuer à progresser sans te blesser : comment espacer tes séances, pourquoi t'échauffer plus longtemps, et comment t'entraîner à la sensation plutôt qu'au chrono. Et je t'explique où j'en suis moi-même dans ma propre remise à niveau sur le 5 km.Dans cet épisode :Le fractionné est-il vraiment plus dangereux pour le cœur en vieillissant ?Que disent vraiment les études sur le fractionné après 60 et 70 ans ?Pourquoi ta VO2max plafonne si tu ne fais que de l'endurance fondamentale ?Qu'est-ce que la sarcopénie et pourquoi elle change tout sur la question du fractionné ?Comment le fractionné devient un outil de préservation musculaire après 40 ans ?Quelles précautions prendre pour continuer sans te blesser (récupération, échauffement, courbatures) ?Comment t'entraîner à la sensation plutôt qu'au chrono pour progresser sans te cramer ?Pourquoi ma propre limite sur le 5 km n'est plus vraiment physique aujourd'hui ?Nouveau : Le protocole Perte de Gras 2026 ❤️ Me suivre : Tous les liens sont ici

Forget the scale - it doesn't tell you what actually predicts longevity. In this episode, Dr. Barrett walks through a 5-part scorecard you can start tracking from home: waist-to-height ratio, grip strength, metabolic markers (glucose, insulin, A1C), VO2 max, and sleep quality. He breaks down the research behind each one and why these fundamentals matter more than any supplement stack, peptide, or hormone protocol - plus simple, practical ways to start improving your score today.. . . Watch the episode on YouTube here!

El VO2 max mide la capacidad del cuerpo para utilizar oxígeno durante el ejercicio y es uno de los indicadores más útiles de capacidad cardiorrespiratoria, rendimiento físico y salud a largo plazo. En este episodio, el Dr. Borja Bandera explica cómo mejorar el VO2 max combinando correctamente intensidad, volumen de entrenamiento, fuerza y composición corporal. ¿Qué papel tienen el HIIT, los sprints y el entrenamiento en zona 2? ¿Cuánto ejercicio aeróbico necesitas? ¿Por qué no basta con entrenar únicamente a alta intensidad? ¿Cómo pueden ayudarte el entrenamiento de fuerza, los ejercicios isométricos y la pliometría? También analiza cómo influye la composición corporal sobre el VO2 max y propone una estructura de entrenamiento progresiva de 12 a 16 semanas para desarrollar la capacidad aeróbica de forma eficiente. Un episodio práctico para entender qué determina tu consumo máximo de oxígeno y cómo organizar el entrenamiento si quieres mejorar tu resistencia, recuperación, rendimiento cardiovascular y longevidad.

The prestige in fitness runs toward the elite. The math runs the other way.Peter Park has trained Lance Armstrong, Justin Verlander, and numerous pro athletes. A pro, he says, arrives already near the ceiling, so a great year of coaching moves them a few percent. A 60-year-old who hasn't trained since the nineties is nowhere near it, and that same year decides how the rest of his life goes.Dr. Kevin White sits down with Peter to talk about why the work is smaller than people expect, why he won't train anyone at their house, the 12-year-olds asking him about peptides, and the snail tattoo he got at 61."I get a pro athlete, I can change like ten percent. I get someone older, I can change their whole life."                                         - Peter ParkLearn more about Peter Park at Platinum Fitness Summerland, platinumfitnesssummerland.com.

Mikael and Jack Hutchens each bring up four things they do in their coaching practice that the research does not support, or does not support in the form they use it. What the evidence says, what they do instead, and the reasoning they would defend it with. HIGHLIGHTS AND KEY TOPICS: Tapering: Mikael prescribes 7 to 10 day tapers where the literature converges on two to three weeks, with a smaller volume cut than the meta-analyses land on. Why he thinks the study populations do not transfer. Torque training: Jack keeps low cadence work in every program despite a review finding no strong evidence it improves performance. His specificity case, and Mikael's rationale from the cadence drop late in an Ironman bike. Electrolytes: why Mikael prescribes them liberally while accepting the evidence is thin, the one athlete variable no study has controlled for, and the profile that really does not need them. Grey zone intervals: polarised training wins the short intervention studies, so why does Jack lean on the zone in between? The time horizon argument, and Mikael's three week VO2max block that stopped working after two. Heat training: ten sessions over two weeks for acclimation, five weeks of five for haemoglobin mass, against Mikael's minimal effective dose. Jack's pushback: does half a protocol buy half the adaptation? Strength training: where it sits in Jack's list of levers when time is fixed, who he does prioritise it for, and Mikael's rules on frequency, session length and the weekly hours threshold to bother at all. Sprint interval training: the protocol with a decent evidence base that Mikael almost never prescribes, what goes in that slot instead, and the cycling study published five days before recording that he never expected to see. Psychology: why Jack spends more coaching time on self-talk, goal setting and confidence than the evidence warrants, and Mikael's theory for why it looks so weak in group studies.

I'm back with Dr. Arshad Hack of LiifeHack Longevity for part two of our conversation all about taking a more intentional approach to our health, performance and longevity. In this episode, we go even deeper into the habits, testing and everyday choices that can help us feel stronger, recover better and support the way we want to age.We talk about everything from VO2 max and zone two cardio to burnout, nervous system regulation, sleep and the routines Dr. Hack personally uses to stay on top of his own health. I also loved hearing more about how data can create positive feedback loops and help us actually see the impact of the work we're putting in.Tune in to learn more on:• Why VO2 max is such an important marker for longevity and how zone two cardio can support cardiovascular health, endurance and visceral fat levels.• How testing and retesting things like VO2 max, strength, balance and range of motion can help us measure progress over time.• Why burnout is so common and the simple practices Dr. Hack recommends for calming the nervous system and creating more balance.• The importance of sleep and why prioritizing recovery can completely change your energy, mood, performance and overall health.• Dr. Hack's own daily habits around nutrition, hydration, fasting, movement and the health data he personally pays attention to.One of my biggest takeaways from this conversation is that longevity is not about doing everything perfectly. It's about creating habits that actually work for your life, paying attention to how your body responds, and being willing to adjust when something is no longer serving you. This is your reminder that sometimes more is not better, whether it's training, work, or the pressure we put on ourselves, recovery and balance matter just as much.So grateful to Dr. Hack for joining me for this chat and sharing so much knowledge with all of us.

Injectable Peptides, Influencers, and Why You Still Got to Lift Lonnie Lowery and Dr. Mike T. Nelson (Phil Stevens out with internet issues) open with an article, "Influencers are promoting dangerous peptides on social media, and regulators are struggling to keep up," detailing how unapproved injectable peptides have moved from niche bodybuilding forums into mainstream social media marketing via before-and-after claims and discount codes. The hosts debate what actually makes these compounds dangerous - the specific amino acid sequence and receptor interactions versus contamination, storage, and immune reactions from the injectable route itself - and connect it back to the show's core message: "you got to lift, bro." They discuss how influencer-driven peptide use sells the promise of results with minimal effort, contrast it with the disciplined training culture of 1980s and '90s PED-era bodybuilders, and share an anecdote from an ISSN conference where two of the field's top protein researchers agreed exercise outweighs protein for muscle retention. Mike notes the near-complete absence of controlled human trials on peptides like BPC-157 and mitochondrial compounds such as BAM15, the confound of concurrent TRT use, and the difficulty of testing vague, subjective outcomes like energy or recovery. They close by discussing the FDA's recent move allowing compounding pharmacies to produce certain peptides and the need for a legitimate, IRB-approved research effort - modeled on how ISSN itself began - to generate real safety and efficacy data before regulators are forced into further reactive policy. 00:00 Welcome and Hosts 00:20 Host Introductions and Hypoxic Training Chat 03:25 You Got to Lift Theme Introduction 03:38 Peptide News Segment Setup 03:55 Article on Peptide Influencers 08:11 Amino Acids or Real Drugs Debate 14:27 Immune Reactions and Storage Risks 20:25 Bypassing Effort and the 80s-90s PED Era 27:03 VO2 Max and Measuring Progress 29:47 ISSN Anecdote: Exercise vs Protein 31:16 Microgravity and Human Need for Stimulus 34:21 Mitochondrial Peptides and TRT Confounds 36:42 Rick Collins and the Data Vacuum 40:13 Path to Legitimate IRB-Approved Studies 40:55 Wrap Up 42:29 Wrap and Disclaimer Donate to the show via PayPal HERE.You can also join Dr Mike's Insider Newsletter for more info on how to add muscle, improve your performance and body comp - all without destroying your health, go to www.ironradiodrmike.com Thank you!Phil, Jerrell, Mike T, and Lonnie

Dr. Dwayne Jackson is a health specialist, medical educator, scientist, and entrepreneur with a PhD in neurovascular physiology. Mitochondrial peptides may be promising, but they cannot replace the aerobic base that makes their effects measurable. Dr. Dwayne Jackson explains AMPK and mitochondrial signaling, what MOTS-c and SS-31 can and cannot tell us, and why fitness data, training, and recovery come before any experimental compound. Expect to learn how aerobic fitness supports strength and Strongman training, why lactate clearance and conditioning can become the rate limiter, what AMPK and mTOR signal, how kidney disease changed Dwayne's perspective on aerobic capacity, where the evidence for MOTS-c and SS-31 is limited, how to design a more useful N-of-1 experiment, and why training, nutrition, recovery, COAs, and third-party testing come before experimental compounds.

Charles Brenner breaks down what the science actually says about NAD+, separating established findings from the claims commonly made in the longevity space. He explains why NAD levels in tissues may matter more than blood measurements, how metabolic stress, alcohol, inflammation, and other conditions can disrupt the NAD system, and how nicotinamide riboside (NR) compares with niacin, nicotinamide, and NMN. The conversation also covers research on exercise recovery, peripheral artery disease, skin health, infection, and wound healing, along with the limitations of current human evidence. Brenner explains why he advises against IV and subcutaneous NAD+, discusses concerns around NMN quality, and challenges popular sirtuin-centered theories of anti-aging while emphasizing the importance of reproducible human research. Charles Brenner is an NAD metabolism researcher whose work focuses on cellular bioenergetics, vitamin B3 biology, metabolic stress, and the pathways that regulate NAD production and utilization throughout the body. Now based at the University of Helsinki, his research has examined how the NAD system responds to conditions ranging from metabolic and liver disease to mitochondrial dysfunction, inflammation, and neurological stress. His work has also helped advance research into nicotinamide riboside as an NAD precursor and its potential applications in human health. Brenner takes an evidence-first approach to longevity science, distinguishing findings supported by controlled human studies from promising but still unproven mechanisms, animal research, and anecdotal claims.   Brenner Lab — Charles Brenner, PhD https://www.brennerlab.net/   Niagen NR Clinical Studies — Niagen Bioscience https://www.niagenbioscience.com/pages/clinical-studies   Nicotinamide Riboside for Peripheral Artery Disease — Mary M.

Harvard followed 74,000 women and found the ones who went to church more than once a week were 33% less likely to die. Northwestern followed young adults and found the most religiously involved were 50% more likely to become obese by middle age. Live longer, get sicker. In this episode, Ben Azadi sits down with Justin, former NHL performance coach and author of the new book Holy Health, to unpack how that contradiction is even possible and what to actually do about it. Justin's new book Holy Health is out now → https://holyhealthbook.com What we get into: Why "burnout in the name of God" is not holy, and the "devil's playbook" that quietly takes your health apart (distraction, disconnection, division, discouragement, depletion) The three things every cell needs to thrive: oxygen, detoxification, and nutrients Oxygen made simple: VO2 max, and how much zone 2 and zone 5 training you actually need each week Why sleep quality, not juice cleanses, is the real language of detox, plus the 3-2-1 rule for deeper sleep Why your "normal" blood work can look fine while your cells are starving, and what homocysteine and methylation reveal Heart rate variability as the body's language, and Justin's honest take on GLP-1 drugs like Ozempic One line to remember: distraction is focusing on good things instead of God things.

Join Dr. Pinkston as she sits down with John Goldman, founder and CEO of Rebel Health Alliance. John shares his journey from feeling chronically exhausted, pre-diabetic, and dependent on a CPAP machine to revitalizing his metabolic health and training to qualify for the Boston Marathon. Together, they discuss the limitations of traditional primary care, the power of deep-dive diagnostics, lifestyle medicine, and alternative models like high-performance primary care paired with community health sharing. Key Topics Covered: The Broken Primary Care System: Why traditional insurance-driven models fail to catch early markers of metabolic dysfunction, visceral fat, and inflammation. Deep Diagnostics: How comprehensive testing—including DEXA scans, VO2 max, DNA analysis, and coronary calcium scores—forms the foundation for long-term vitality. Overcoming Obstructive Sleep Apnea: John's personal experience transitioning to a CPAP/BiPAP and eventually resolving his condition through weight loss and metabolic restoration. The Rebel Health Model: Combining full-time physicians, strength coaches, registered dietitians, and genetic counselors into a seamless, accessible care team. Ejecting from Insurance: How direct primary care paired with community-based health sharing offers financial protection without corporate middleman restrictions.

Daniel Rowland and Mikael are back for another research roundup with four recent studies. What blood biomarkers do and do not tell you about training load in elite triathletes, why two athletes with the same VO2max can have very different thresholds, what actually predicts running injuries in a cohort of 5,200 runners, and whether supersets deliver the same strength gains in a third less gym time. HIGHLIGHTS AND KEY TOPICS: VLaMax (maximal glycolytic flux) and metabolic thresholds: the first evidence in real athletes that at a given VO2max, a higher glycolytic rate means a lower threshold power. How VLaMax is measured, why sprint power on its own tells you little to nothing, and whether you can and should measure it and base training decisions off it. How much running is too much: in 5,205 runners tracked over 18 months, a single run 10 to 30% longer than the longest run of the previous 30 days came with a 64% higher injury risk, and bigger jumps than that led to injury risk increasing by well over 100%. Why the acute:chronic workload ratio and the classic weekly 10% rule showed little or no relationship with injury, and why you should never use the performance management chart for controlling running load. Practical long run progression for a marathon or an Ironman, and the one TrainingPeaks chart Mikael looks at more than any other. Four seasons of blood urea and creatine kinase in 20 elite (some world class) triathletes: urea tracks training load, CK does not, and a single reading against a reference range means almost nothing. Why the ratio of objective to subjective training load may be the most useful signal a coach has, and a heuristic for using it in practice. Supersets versus traditional sets: the same strength, hypertrophy, power and body composition gains in 36% less time, 44 minutes per session against 69, and how to apply that to a triathlete's lower body dominant strength programme.

Become a Supporter of The Real Science of Sport, and you get ad-free listening, an Applied Science bonus show every week, plus a seat at the best conversation in sport. All for less than a decent gel.Show notesJosh Kerr, the Commonwealth Games, a stitch explained, the Tour de France Femmes, and yet another South African schoolboy rugby doping ban. In today's show:(00:00:38) We joked before Glasgow that this might be the last Commonwealth Games we ever see, and we were wrong. They survived in a cut-down, ten sport form, with India in 2030 and interest from Nigeria and New Zealand for 2034. We debate whether a smaller, cheaper games is actually the point rather than the problem, and what it means that the BBC's sub-one-million-pound bid was rejected, leaving Josh Kerr's mile watched by 200,000 people when Eilish McColgan's 10,000m in 2022 drew six million.(00:02:37) The performances, including Emmanuel Eseme of Cameroon running 9.83 in apocalyptic rain, three women under 11 seconds, and Josh Kerr's utterly dominant 3:54 mile off a jogged first kilometre. With the fastest mile in history relative to his peers and a devastating kick, how does anyone actually beat him now, and will the 1500m world record follow? Kerr says he is flying a little close to the sun, and we explain why staying in world record shape is like sitting in the death zone on Everest.(00:24:13) Laura Muir crossed the line 16th and collapsed after a stitch at 3km, so what actually causes one? We go through exercise related transient abdominal pain, the old diaphragmatic ischaemia theory, the newer parietal peritoneum irritation explanation, why shoulder tip pain is referred pain, and the risk factors including drinking before you run, being younger, being female, and having weaker trunk muscles.(00:33:56) Ingebrigtsen returns at the Euros over 5000m off two disrupted seasons and Achilles surgery, and we're not sure it'll be the comeback people hope for.(00:44:52) The Tour de France Femmes is brewing into a genuinely great race, with time gaps after the time-trial necessitating attacking racing as the Tour heads into its hilly and mountain stages. Niewiadoma and Ferrand-Prevot in particular need to claw back big time, while Reuser defends and Vollering waits ominously in pole-position. Instead the world's media is writing about padded bras. Why does cycling always shoot itself in the foot, and why is it a headline for the women when it was an incidental for the men?(00:47:40) Tadej Pogačar's estimated VO2max of over 100 is doing the rounds, using exactly the methods Ross was hammered for using on Contador and Froome fifteen years ago. We explain the modelling, why assumptions can spit out anything between 85 and 101, and what that means for comparing Pogačar to Pantani on Alpe d'Huez.(00:55:56) The full Markéta Vondroušová decision is out, and it reads very differently to the version that had tennis players outraged. Plus a hard look at South African schools rugby, where Deon Botes is the third schoolboy banned in months, this time for a supplement his father allegedly bought for cash from a stranger outside a pharmacy with "ultimate test booster" on the box.(01:12:47) Jannik Sinner walks away from a potential clean sweep of the Masters events to play less tennis before the US Open, while Carlos Alcaraz withdraws from Cincinnati and extends a wrist injury layoff that has now cost him May, June, July, and half of August. Two very different answers to the same question, and one that echoes Josh Kerr's approach to racing.(01:15:00) And finally, an update on Anna's ride around Australia. Nine days, 976km, 7,940m of climbing, one chain change, and three magpie attacks. Hosted on Acast. See acast.com/privacy for more information.

Mikael and Jack answer listener questions on indoor versus outdoor FTP differences, whether time in zone is all that matters and how to optimise interval intensity, a first 70.3 debrief covering swim breathing problems and bike cramps, and lots more! Email us your questions, or answer the question prompts in our Instagram stories to get your questions answered on the next Q&A. HIGHLIGHTS AND KEY TOPICS: Why indoor and outdoor FTP differ, whether a 20-watt gap is normal, and why Mikael has never had an athlete test both. Fans and airflow as the most underrated indoor cycling upgrade, including the research showing 40 km time-trial power is maintained up to 27°C when airflow matches outdoor riding speed. How to back-calculate an outdoor FTP from your own sweet spot and threshold interval data rather than doing a second test. Why a 10-minute interval should not be done at your 10-minute power, and how to perform a session so you finish at a session RPE of 7 to 8 with something left in the tank. Is time in zone all that matters? The same power and the same total work can produce very different internal loads. Minimum rep lengths if you want to spread work through a longer ride: 4 to 5 minutes for VO2max reps, 10 to 15 minutes for threshold reps. A first 70.3 debrief: why the swim breathing fell apart and how to break the hypercapnia (CO2 buildup) spiral, and what most likely caused hamstring cramps at 70 km on a hilly bike course. Instagram questions: finding your bike power in the first 20 minutes of a race, whether a VO2max block followed by a threshold block is a silver bullet, training after dental surgery, splitting 120 g of carbs per hour, and preparing for the Ironman Nice climb when you have no long climbs.

Robbie Deckard is a professional middle-distance triathlete and triathlon coach, and the founder of Freaky Fast Aero Accessories. In this episode, Robbie and Mikael dig into the real differences between American and European training methods, using lactate and VLaMax to optimise training and performance, and how age-group triathletes can apply lab-grade thinking to swim, bike and run training without actually going into a lab. HIGHLIGHTS AND KEY TOPICS: The real difference between FTP-centric American coaching and the German/Benelux style built around VLaMax, VO2max and physiological profiling. The evolution of VLaMax based training: from Alois Mader's 1970s model through Jan Olbrecht to current day coaches like Dan Lorang. Robbie's case for still doing dedicated VO2max work, including a case study that took an amateur cyclist's VO2max from 74 to 87 mL/kg/min over 58 weeks of block periodisation. Why building maximal aerobic power early is more valuable long-term than chasing threshold gains, and how that shapes the "durability" that separates junior and U23 cyclists from senior professional cyclists. How Robbie profiles athletes using LT1, LT2 and 5-minute power (or 500 yd swim time, or mile run time), and what typical percentage utilisation looks like for age-groupers versus elites. How he prescribes endurance, threshold and VO2max sessions in practice, including cues (power, pace, RPE), lactate targets, and why exact wattage precision on threshold work matters less than people think. Practical advice for age-groupers: open-water swim skills and ankle-band drills, running road races for pacing and durability, and hill running for strength and economy. Improving aerodynamics on a budget: reduce frontal area first, then refine airflow, and how to measure progress without a wind tunnel using Golden Cheetah or a simple speed sensor.

Six days before he sat down for this conversation, he ran a marathon. Then he explained what the race did to his brain. When you run 26 miles and your glycogen runs out, your brain still needs energy, so it starts stripping the fatty myelin off its own neurons and burning it for fuel. MRI scans caught a 20% drop in myelin up to two months after a marathon, and cognitive testing showed real impairment for about a month. In this episode, Louisa sits down with Brady Holmer, exercise physiologist, 2:24 marathoner, and author of VO2 Max Essentials, for one of the most practical conversations on aerobic fitness, brain health, and longevity the show has recorded. They cover why "marathon brain" is real but temporary, the menopause parallel where a starved brain catabolizes its own white matter, and whether pre-loading ketones or omega-3s can protect your myelin through a hard endurance effort. Then Brady breaks down VO2 max the way almost nobody does: not as a heart-and-lung number, but as a five-step oxygen cascade running from your lungs to your mitochondria, and why the bottleneck moves from your heart to your muscles as you age. You will learn the exact VO2 max floor below which everything becomes a maximal effort, the "50 at 50" target, and why women should aim for 40 to 50. Brady also lays out how the brain itself gates your fitness through myokine signaling, why the one to two hours after training may matter more than sleep for adaptation, and the truth about "non-responders" and the IGF binding protein biology behind trainability. Then the protocols: why the Norwegian 4x4 beats Tabata for VO2 max, how sauna and post-exercise ketones amplify the same session, why sleep consistency beats sleep duration, and the single weekly workout Brady says everyone should be doing for both VO2 max and brain health over the next decade.

Plus: Hyperbaric chambers, red-light therapy, mRNA, cancer research, and the surprising importance of boredom and friction. Kara Swisher is a veteran tech journalist, host of the Pivot podcast with Scott Galloway, and one of the most influential voices covering the intersection of technology and power. Her new CNN documentary series, Kara Swisher Wants to Live Forever, takes on the longevity industry — separating genuine medical breakthroughs from the pseudoscience being sold to anyone with a credit card and a fear of aging. Kara Swisher has been covering Silicon Valley longer than most of its billionaires have been rich — and she's watched them turn a simple fear of death into a multi-billion dollar industry of expensive, largely unproven interventions. After her own stroke at 49, she decided to investigate: what actually works, what's a grift, and what does the science really say about living longer? The result is a new CNN documentary series that's part BS-detector, part genuinely hopeful look at the medical breakthroughs that could change everything. This conversation covers both. We talked about: Why biohacking culture is basically a men's eating disorder dressed up as science Bryan Johnson, Peter Attia, and what Silicon Valley gets catastrophically wrong about longevity The supplements, therapies, and interventions that are mostly hype (peptides, hyperbaric chambers, red light therapy, full-body scans) What VO2 max actually measures — and why it's one of the few metrics worth tracking GLP-1 drugs: the real promise behind the Ozempic headlines The mRNA breakthroughs that could produce a pancreatic cancer vaccine Why your relationships are a more powerful longevity drug than anything you can buy The case for boredom, friction, and putting your phone down How thinking about death every day can make you happier and less afraid Get the 10% with Dan Harris app here Sign up for Dan's free newsletter here Follow Dan on social: Instagram, TikTok Subscribe to our YouTube Channel This episode is sponsored by: Eight Sleep: Use code DanHarris at eightsleep.com/danharris for up to $350 off the Pod 5, with a 30-day trial if it's not for you.
