Megan Eckert is back inside one of endurance sport’s strangest tests: the GOMU Six-Day World Championship. After setting the women’s world record at 603.156 miles, she enters the 144-hour event in Balatonfüred chasing the 606.243-mile American men’s record. We break down what it takes to spend six days circling the same short loop, how athletes balance sleep against distance, and why three additional miles become monumental after already covering more than 600.

Then we turn to the Brussels Diamond League Final, where Busang Collen Kebinatshipi ran 43.40 in the 400 meters and Emmanuel Wanyonyi delivered another 1:41 performance over 800 meters. We also discuss Masai Russell’s 12.09 hurdles world record, the race to break the 12-second barrier, and Cole Hocker’s latest result in a loaded 1,500-meter field.

From there, we head to IRONMAN 70.3 Zell am See-Kaprun, where Lasse Nygaard Priester set a course record and Laura Philipp won just 15 days after completing a full IRONMAN. That leads into a larger conversation about why elite athletes are increasingly becoming content creators—and how YouTube is changing the relationship between athletes, fans, and sponsors.

Finally, we preview the new World Athletics Ultimate Championship, a three-night season finale featuring nearly 400 athletes and a $10 million prize purse. We close with Addisu Gobena’s Sydney Marathon course record, the mental cost of chasing an Olympic Trials qualifying time, HYROX’s first five-day event in Washington, D.C., and the IAMS Dog Run Marathon challenge.

UTMB week delivered one of the most dramatic collections of races of the year. Former Olympic 1,500-meter runner Lauren Gregory won the women's OCC after a three-second sprint finish against Naomi Lang, while Cristian Minoggio and Yngvild Kaspersen claimed the CCC titles. Then Ben Dhiman completed the 174-kilometer UTMB in a record-breaking 18:16:29 — more than an hour faster than the previous mark. We break down Dhiman’s historic performance, the arrival of a new generation of elite ultrarunners, and Courtney Dauwalter’s decision to attempt UTMB only 48 days after Hardrock before ultimately dropping around mile 40.

The Leadville Trail 100 also returned on its wildfire-altered course, with Adrian Macdonald securing his third victory in 15:47:23 and McKendree Hickory winning the women’s race in her 100-mile debut. We discuss how results should be judged when fire, weather, or other conditions force organizers to change an iconic course. From there, we move to the track, where Alison dos Santos ran a 45.80 world record in the 400-meter hurdles before Yomif Kejelcha completed a half marathon in 56:51 — averaging approximately 4:20 per mile and closing his final kilometer in 2:32.

Then we get into the growing trail-running footwear arms race. Adidas unveiled the $500 Agravic Speed Ultra Evo, bringing technology from its road-racing shoes into a lightweight trail platform, while Nike revealed the unusually named ACG Picklejus with dual-density ZoomX foam and its new GOATEK traction system. We discuss whether marginal performance improvements can justify a $500 trail shoe and why nearly every major footwear brand is using UTMB week to make its biggest announcements.

Finally, Garmin launched the fēnix 9 and fēnix 9 Pro, featuring a thinner titanium design, an AMOLED display reaching 3,000 nits, optional inReach connectivity, and new stamina zones designed to estimate how long an athlete can sustain different efforts. We break down whether that information can help athletes push further or convince them to stop before reaching their actual limit. We close with Kyle from NELK announcing seven marathons on seven continents in seven days and the ultrarunning community rallying around Jeff Browning following the serious cardiac emergency he suffered during the TDS.

The Leadville Trail 100 is moving forward with an altered course after the Willow Fire affected thousands of acres surrounding the original route. Runners will still cross Hope Pass twice, but the revised course removes several familiar sections and contains approximately 2,000 fewer feet of climbing. We discuss whether record performances can still be compared across different versions of the race and how trail running continues to adapt to unpredictable conditions.

Then we turn to UTMB, where the men’s race has been reshaped by the withdrawals of Kilian Jornet, Jim Walmsley, Mathieu Blanchard, and defending champion Tom Evans. On the women’s side, three-time winner Courtney Dauwalter returns to challenge defending champion Ruth Croft. We break down the new competitive landscape, UTMB’s impressive live coverage, and why following the sport’s biggest week can still be surprisingly confusing.

From there, 91-year-old Dale “Greybeard” Sanders is attempting to reclaim the record as the oldest person to complete the Appalachian Trail. John Kelly is also back on the trail chasing the overall supported fastest known time after a nerve problem ended his previous attempt around 1,900 miles. We discuss longevity, managing risk, learning from failure, and what remains possible when athletes adapt the challenge to the body they have today.

We also cover Oura’s move toward AI-powered health interpretation, the Coros and Satisfy watch collaboration, rumors surrounding Garmin’s next Enduro and Fenix devices, and why Garmin may need separate performance and wellness modes. Finally, the Lasso Backyard Ultra ends after 94 loops and approximately 630 kilometers, while Matt Johnson completes Project Seven by covering 899.2 miles across seven days in support of ValorFit and military veterans.

Google is taking direct aim at Garmin with the Pixel Watch 5. The company claims its new GPS system can provide twice the route accuracy of the Pixel Watch 4 in difficult environments and outperform devices like the Garmin Fenix 8 Pro and Apple Watch Ultra 3 in internal urban testing. But instead of relying entirely on a stronger GPS receiver, Google appears to be using its knowledge of roads, buildings, and maps to correct routes after a workout. We break down whether software-assisted GPS can genuinely compete with Garmin’s dedicated fitness hardware and what happens when your watch starts interpreting your run instead of simply recording it. From there, we look at Google’s new Health Guardian features, which aim to identify longer-term wellness trends involving blood pressure, insulin resistance, sleep breathing, and dangerous drops in blood oxygen — without crossing the line into clinical diagnosis.

Then we get into Project Seven, Matt Johnson’s attempt to complete seven full Ironman-distance triathlons in seven consecutive days to raise money for ValorFit and support military veterans. We discuss the physical and logistical demands of swimming 2.4 miles, biking 112 miles, and running a marathon every day for an entire week, why endurance challenges like this are often decided by recovery and nutrition, and what makes the mission behind the event more important than the finish times. We also cover Courtney Dauwalter’s surprise return to UTMB and whether one of ultrarunning’s greatest athletes can reclaim her title after a disappointing result — especially in a race where 108 miles, nearly 10,000 meters of climbing, weather, nutrition, and a single mistake can change everything.

Next, a new avocado oil study raises serious questions about what consumers are actually buying. Researchers tested 54 processed foods marketed as containing avocado oil and found that 48 of them — roughly 89% — had oil profiles inconsistent with authentic avocado oil. We break down what the testing can and cannot prove, why products like chips, mayonnaise, and salad dressings are difficult for consumers to evaluate, and how premium health claims can become powerful marketing tools even when the underlying ingredients may not match expectations. That leads into a broader conversation about acquisitions in the health and wellness industry, what happens when trusted brands are bought by larger companies, and whether consumers can rely on a brand’s reputation after its ownership and priorities begin to change.

Finally, Spotify is moving deeper into fitness with a new Running Mode designed to build personalized playlists around the type of run, desired tempo, and musical preferences of the user. We discuss whether Spotify can compete with guided running platforms by using the listening data it already has and why automatically matching music to the intensity of a workout could be more useful than another generic training plan. We close with reports that Apple is exploring a screenless fitness band that could compete with Whoop and other recovery-focused wearables. We break down why Apple may want a device designed for continuous health tracking rather than notifications, how artificial intelligence could turn years of Apple Health data into practical recommendations, and the privacy trade-offs that come with allowing technology to understand more about your body than ever before.

The HYROX gold rush is officially underway. Nike entered the hybrid-racing arms race with an entire two-shoe system built specifically around the demands of running fast while still being stable enough for sleds, lunges, and wall balls. The Hybridfly brings ZoomX, a carbon Flyplate, and Zoom Air into a race-day model, while the Hybrid RN serves as the training counterpart. We break down whether Nike has actually solved the hybrid-shoe problem, why Puma's early investment in HYROX may have given it a massive head start, and how Adidas is entering the same fight as nearly every major footwear company tries to claim a piece of one of fitness's fastest-growing categories. From there, we look at UFC lightweight contender Arman Tsarukyan completing his first HYROX less than 24 hours after winning a grappling match, teaming up with former Formula 1 driver Nikita Mazepin to finish in 1:06:39 — another example of just how transferable the conditioning of elite combat athletes can be.

Then we get into a new eight-week bench press study asking a surprisingly practical question: how much should the bar actually slow down before you end a set? Researchers compared different training loads and velocity-loss thresholds in 158 trained men and found that heavier training with more moderate fatigue produced the largest average strength gains, while pushing sets deeper into fatigue produced more muscle growth — but required substantially more repetitions. We break down what bar-speed loss actually means, why grinding every set may be counterproductive if strength is the goal, and how lifters can apply the idea even without expensive velocity-tracking equipment.

Finally, P&G agreed to acquire supplement company Thorne in a $3.8 billion cash deal, raising a bigger question than the price tag: what happens when a brand built largely on practitioner trust, testing standards, and credibility gets absorbed by one of the world's largest consumer-goods companies? We discuss why the acquisition makes sense for P&G, why longtime Thorne customers may be skeptical, and what could happen to that trust if the brand's priorities begin to change. We close by breaking down a viral post linking low-calorie sweeteners with faster cognitive decline, what the underlying observational research can and can't actually prove, and why the headline is much scarier than the conclusion deserves.

In Episode 15, We break down Jolliffe’s historic 20:53:41 victory, Carmen Maria Perez’s women’s course record and second-place overall finish, and the online debate surrounding the finish-line ribbon, race tracking, and limited coverage of the event.

Then, the conversation turns to Aurélien Sanchez’s reported supported fastest known time on the Pacific Crest Trail: 45 days, 20 hours, and 15 minutes across roughly 2,650 miles. What does it take to manage the sleep, logistics, injuries, and constant movement behind an attempt like this?

Finally, we explore Red Bull Gym Clash, a worldwide gym-versus-gym functional fitness competition. They break down the team format, qualification process, workouts, and what the event says about the explosive growth of hybrid fitness.

He called his shot — and delivered one of the most iconic runs in track history. At the London Diamond League, Great Britain's Josh Kerr broke Hicham El Guerrouj's mile world record, running 3:42.66 to take 0.47 seconds off a mark that had stood for 27 years and become the first man ever under 3:43. He'd announced the attempt ("Project 222") months in advance and built his whole season around it. We break down not just the run but the debate it reignited: how much of a modern record is the athlete versus the engineering around them — wave-light pacing, carbon-plated shoes, custom spikes, and wearables — and why, if it were only the tech, everyone behind him would've run it too. From there, triathlon's Marten Van Riel turned one of Ironman's toughest courses into a speed showcase, smashing the Ironman Lake Placid course record in 7:41:57 (a 2:34:49 marathon) for his first-ever full-distance Ironman win — and setting up a blockbuster Kona showdown with Kristian Blummenfelt.

Garmin finally entered the screen-free wearable race with the CIRQA Smart Band — a Whoop-style tracker that runs its core health, sleep, and recovery metrics with no required subscription (with an optional Connect+ tier for extras) — and we get into who a screenless band is actually for. Then Nike ACG turned its Zegama trail-running platform into a lightweight, ZoomX-cushioned hiking boot, part of a broader shift away from heavy traditional boots.

Jayden's two-a-day bike blocks and the psychology of self-image, our accidental 12-mile trail run in the mountains, and a heated debate about whether Coca-Cola's redesign means Coke Zero is officially the default (and whether Diet Coke is doomed).

Experience is having a moment. At the Hardrock 100 — 102 brutal miles and 33,000 feet of climbing through Colorado's San Juan Mountains — 50-year-old Ludovic Pommeret won for the third straight year and smashed the overall course record (21:11:36), while Courtney Dauwalter took her fourth title and reset her own clockwise record. It sparks a bigger debate we dig into: in ultra-endurance, do experience and durability beat raw youth and VO2 max? Then there's a feat that sounds impossible — one athlete became the first ever to complete 100 HYROX Pro races in 100 consecutive days, running 800 km and grinding through 800 stations without a single day off, on a Puma-built course recognized by the German Record Institute. Speaking of Puma, we break down Project Podium, the biggest sub-elite program in HYROX history, which turns every solo podium finisher at the Stockholm World Championships into a sponsored Puma athlete.

On the science side, a UK Biobank study of nearly 83,000 people found that heavy evening light exposure (over 1,000 lux between 8 and 11:30 PM) was linked to meaningfully higher rates of age-related eye disease — 31% for macular degeneration and 47% for glaucoma — which sends us down a rabbit hole on indoor LEDs, natural light, and circadian health. And we close on a simple, cheap tool blowing up online: why cooled potatoes — the single most filling food ever tested on the satiety index — turn into resistant starch that may help with fat loss and blood sugar.

This week we cover Sam Laidlow's record-setting Challenge Roth win on Canyon's unreleased Speedmax CFR (and whether the bike or the athlete deserves the credit), an 18-year-old outsprinting an Olympic champion at the Prefontaine Classic, and a two-year fish oil trial that got more DHA into the brain but failed to improve memory. We also break down WHOOP hiring Nike's former global CMO, Gymshark founder Ben Francis eyeing a stake buyback, and Andy Galpin's science-backed guide to HYROX training.

Plus: VO2 max reality checks, why most people aren't training hard enough to need the recovery they think they do, and the carbs-vs-fat unlock for body composition.

Records are falling across running all at once — and that's almost never an accident. At the Western States 100, France's Vincent Bouillard smashed a course record that had stood since 2019, running 13:46:15 as the entire men's podium ducked under the old mark; on the women's side, Jenn Lichter broke Courtney Dauwalter's "untouchable" record in her 100-mile debut, on a day with the highest finish rate in the race's 53-year history. Days later at the Paris Diamond League, 20-year-old Cameron Myers ran 3:28.00 for a new Australian 1500m record, and Switzerland's Audrey Werro clocked 1:53.80 — the third-fastest women's 800m in history and the first sub-1:54 ever, closing in on a world record that has stood since 1983. We break down why it's all happening now: super shoes, high-carb fueling, deeper and better-funded fields, and smarter data — the signs of a rare inflection point, the same kind of moment as the first sub-4 mile or sub-2 marathon.

Then the NIH's All of Us program just became the world's largest integrated genomics and health database — over 747,000 participants and 535,000 whole genome sequences linked to nearly 482,000 medical records, with 86% of participants from communities historically left out of biomedical research. We get into why that diversity actually matters for medicine, and where bigger data can still go wrong. Then there's Catherine Breed, who just launched "Swim California" — a first-of-its-kind attempt to swim the entire 900-mile California coast from Oregon to Mexico under marathon-swimming rules, five hours a day for four months.

Plus our weekly check-in on Tyler's road to HYROX Dallas — getting back into training after time off, using HRV to know when to back off, and building the block around VO2 max and zone 2 — and a full rundown of upcoming events, from the Tour de France and Hardrock 100 to the Ironman World Championship in Kona.

Your wearable is becoming a medical device. WHOOP just partnered with HealthEx to pull your actual electronic health records into the app — so diagnoses, medications, and procedures sit alongside your recovery, strain, and sleep, powered by WHOOP AI and "My Memory." Oura is heading the same direction, quietly turning the ring into a virtual doctor's office with cognitive testing and in-app telehealth. We dig into what this clinical era of wearables really means: the accuracy-vs-trends debate (and what the Apple Heart Study and validation research actually show), the privacy tradeoffs, and the thornier question of AI predicting — and even prescribing — your medication. Plus a new meta-analysis in the Journal of the American Heart Association finding wearables meaningfully boost activity in people with heart disease, and a head-to-head of Apple Watch vs. Whoop vs. Oura vs. Fitbit.

From there we get into the explosion of hybrid fitness: Nike-backed ONE LDN raising £2.5M to scale its HYROX-style training club, and what the rise of community-driven "all-in-one" gyms means for the industry. We break down Marten Van Riel going a perfect 6-for-6 in Ironman 70.3 with a course-record win at Elsinore, the contrast between data-driven Norwegian training and South Africa's deep ultra-running culture, and how HYROX has done something we've never seen before — spawned an entire category of shoes built from the ground up (Puma, Adidas, On, Brooks).

UFC Freedom 250 takes over the South Lawn of the White House — and on a card where all seven fights ended inside the distance, Justin Gaethje stopped previously-unbeaten Ilia Topuria to claim the undisputed lightweight title. Dr. Sarah Ruggins pulls off one of the most staggering rides in endurance history, crossing the length of Europe from Tarifa to Nordkapp in 13 days, 20 hours, and 27 minutes — beating the outright record by three days on roughly three hours of sleep a night. Midjourney, of all companies, unveils a 60-second full-body ultrasound scanner (and a San Francisco "spa" to house it). The HYROX World Championship delivers a wall-ball thriller and reignites the debate over judging and 15-second penalties. And as the FIFA World Cup lands in the US, it shatters a 32-year-old single-day attendance record with 281,223 fans.

We also dig into an NSCA coach's deep dive on overtraining in endurance athletes — what causes it, how to catch it early with HRV, and why a smart taper can actually make you faster — plus a stacked run of quick hits: 24/7's Mission 247 endurance race, Reuters on World Cup heat risk, Noah Lyles' 150m world best (14.67), Bryan Johnson's new Akkermansia gut product, Taiwan's Fan Chung-chia setting a 216 kg bench press world record, a 100-mile run honoring America 250, and AG1's creatine-loaded "AG1 Pro."

And our Study of the Week: a Scientific Reports paper testing whether AI-personalized training can out-perform standard programming — and by how much.

20-year-old Auburn hurdler Ja'Kobe Tharp ran a 12.75 to break the 110-meter hurdles world record at the NCAA Championships — the first world record set at that meet in 50 years, and he says he had more in the tank. We dig into the Surgeon General's new advisory reframing kids' screen time as a public health issue (where it's right, and where it pulls its punches), plus a longevity arms race heating up: David Sinclair's Life Biosciences dosed its first patient in an FDA-approved cellular-reprogramming trial, right as Russia reportedly pours $26 billion into its own anti-aging research.

On the endurance side, two unreal stories. Dr. Sarah Ruggins — a Canadian ultra-cyclist who lost years of her life to a brutal nerve condition before picking up a bike just three years ago — is attempting the fastest-ever ride from the bottom of Europe to the top: 6,000km, nine countries, 22 hours a day in the saddle on 90 minutes of sleep. And French ultrarunner Aurélien Sanchez, the 2023 Barkley Marathons champion, is taking a high-risk crack at the Pacific Crest Trail speed record.

Whoop and Strava finally connecting, a kimchi bacterium that cleared most nanoplastics in lab testing, the FDA approving bemotrizinol (the first new sunscreen filter in the U.S. since the '90s), a study tying ultra-processed food to worse attention, a JAMA look at how few people actually share their wearable data with doctors, and New Orleans' "healthy default" drink rule for kids' meals. We also open with some real talk on why running might be the wrong first move for fat loss.

And our Study of the Week: a 2026 systematic review and meta-analysis on "exercise snacks" — breaking up long stretches of sitting with short, frequent walking breaks. The finding: a two-to-three-minute walk every 20-30 minutes after meals meaningfully lowers your post-meal glucose and insulin, with walking beating standing and frequency mattering most. The most underrated metabolic lever might just be a short walk.

Seven weeks in, and the theme is human limits — on the mountain, on the treadmill, on the gravel, and inside your own head. American ultrarunner Tyler Andrews summits Everest in nine hours, fifty-five minutes, an oxygen-assisted base-camp-to-summit speed record that erases Lhakpa Gelu Sherpa's 2003 mark by a full hour and one minute, with a 16:32 round trip on his sixth attempt in two years. We break down the physiology of roughly 11,500 feet of vertical over 8.4 miles through the Khumbu Icefall, the South Col, and the Hillary Step.

Then we set the table for the HYROX World Championships in Stockholm, June 18–21 at the Strawberry Arena, where only the top half-percent of the sport even qualifies. We compare the three men we think decide it: Alexander Roncevic, who broke the sub-52 barrier at a blazing-fast Warsaw; defending champion Tim Wenisch; and the showman, three-time champ Hunter McIntyre — their fastest times, their three-race averages, and why Hunter going back to his strength roots (and chasing another wall-ball record) makes him our pick. Plus Swiss ultra-endurance rider Robin Gemperle wins a brutal, mud-clogged Unbound Gravel XL — 356 self-supported miles across the Flint Hills of Kansas in roughly 21 hours, on a prototype Scott 32-inch-wheel bike that will never hit the market, after walking close to a half marathon through the mud. And the world's first 24-hour treadmill ultra, where teams of four trade off across forty treadmills inside a factory-turned-rave, and why running in place might be the hardest endurance test there is.

On the science side, creatine is still mainstream. New work frames grip strength as a validated proxy for health span, biological age, and all-cause mortality risk, and ties consistent creatine intake to meaningful gains in lean body mass and combined grip strength, with favorable trends in bone mineral content and body fat. It is still the most-researched supplement on earth, and no, it will not make you puffy. We also pick up the wearable AI race we called last episode: Strava ships a native MCP connector that plugs your training data straight into Claude for its 195 million users, and we map where Garmin, Whoop, Google's Gemini-powered band, and Apple's incoming on-device Siri overhaul at WWDC all land in the fight for your wrist. And NewLimit, backed by $435 million from Founders Fund, moves epigenetic reprogramming from mice toward human trials in the liver — the same thesis David Sinclair was chasing back in Episode 2, just with serious money behind it.

Quick hits include David Protein's protein ice cream finally landing in real life — sold out, ninety dollars for six pints, thirty grams of protein, and an X comment section that lost its mind over whether it is even legal to call it ice cream — Nude Miami opening as a self-proclaimed "healthiest grocer" and what a seed-oil-free, bougie wellness retail wave says about a coming health-class divide, and Dr. Rhonda Patrick on Matt Walker's math for how much time you actually need in bed to bank 7.1 hours of sleep.

Then the Deep Dive returns, on meditation and the modern attention crisis: why a world engineered to fragment your focus is not a willpower problem, what the practice of noticing and returning actually trains in your prefrontal cortex, how short-form dopamine resets your baseline so the good things start to feel boring, and why reclaiming your attention might be the most radical thing you can do. It turns into an honest conversation about listening, curated algorithms, and whether most people's intentions are good.

Better health creates better humans, and better humans build a better society.

Six weeks in, and the wearable arms race is the story. We break down Oura's Ring 5 — 40% smaller, with AI health guidance, GLP-1 tracking, and a new health radar watching nighttime blood pressure and breathing trends — landing alongside a confidential IPO filing at a roughly $11 billion valuation off 5.5 million rings sold. Then we get to where the real innovation is headed: a UC Irvine sweat sensor that reads lactate, glucose, urea, and cortisol straight off your skin — battery-free, powered by your phone's NFC, self-cleaning, and continuously wearable. For athletes, a live lactate read could reinvent how you train your zones. Plus Strava's full strength overhaul — 14 partner integrations, auto-generated muscle maps, and a real lifting log for its 195 million users — and where Whoop, Google's Fitbit Air, Garmin, and Apple's incoming on-device AI all land in the fight.

On the science side, Andy Galpin breaks down a 2025 paper on why some people gain muscle faster than others — and why "I'm a non-responder" is almost always a measurement, dosing, or consistency problem, not your DNA. We also run through Brian Johnson's five pillars of longevity: strength, Zone 2, high-intensity cardio, mobility, and the one everybody skips — balance.

And over at the Enhanced Games, a peptide-era/PED swimmer dips seven hundredths of a second under the official 50-meter freestyle world record — unsanctioned by the sport, but worth a seven-figure prize.

Quick hits include Hunter "The Bulk Pony" McIntyre hitting a new record in his home HYROX sim, Hercules becoming the fastest person ever to run across Greece, Diplo calling wellness the new nightlife as run clubs replace nightclubs, a longevity daily-five movement routine worth stealing, Dr. Rhonda Patrick on whether you can mix creatine and caffeine, the David Protein vs. RX Bar debate, and the America 250 merch wave. We also recap our own Memorial Day Murph and the 12-week block we just started — VO2 max, lactate-threshold testing, and strength.

And our Study of the Week: a 2026 umbrella review and meta-analysis on resistance training in kids and adolescents with overweight or obesity. The takeaway — short, structured 8-to-12-week strength blocks reliably cut body fat, add lean mass, and build strength across every age group, while longer programs tend to stall on motivation, not physiology. Heavier kids actually tolerate lifting better than punishing cardio, and the early wins build the confidence that makes it stick. Which is the whole thesis of the show: better health creates better humans, and better humans build a better society.

The Headlines:
560–610 minutes a week for your heart — A British Journal of Sports Medicine study (17,000+ adults, ~8 years) found the standard 150 min/week cut cardiovascular risk just 8–9%, while real protection (30%+) took 3–4x that. Is the old guideline a minimum, not a target?

Increasing healthspan: the unique role of exercise — An American Physiological Society review on adding disease-free years, plus the John Cleese "silly walk" finding that moving inefficiently on purpose can raise energy burn ~250% — for free.

Nike Training × The Yard Gym — Nike's first official global training partner, and what it signals about brands moving from selling gear to owning the gym itself.

Are you exercising at the wrong time? — Chronotypes, your master clock vs. peripheral clocks, and why training out of sync raises perceived effort and blunts adaptation.

Study of the Week — Exercise in the workplace: mood lifts within ~5 minutes of moving, and an hour of weekly work time spent training showed no drop in output. The case for movement during the workday.

Quick hits: Bryan Johnson's new female longevity protocol · Huberman's BPC-157 jab · the Cam Hanes peptide controversy · a 19-year-old's 2,800 lb car-pull marathon world record · John Summit on running vs. DJing.

The takeaway: more movement matters — but the win isn't 10 hours in the gym, it's weaving movement into the hours you already have.

New episodes now coming every Monday!

Arda Saatçi's 604-kilometer Red Bull Cyborg Season Ultra 600 from Death Valley to Santa Monica Pier — 372 miles, 123 hours, over a million live viewers, and a message that your limits are further away than you think. He didn't hit the 96-hour target, but the story of why that didn't matter is the headline.

A 47-year Karolinska Institute longitudinal study tracking the same 427 individuals from age 16 into their 60s found that physical capacity peaks around 35 and declines from there — across aerobic capacity, strength, endurance, and power. The hopeful part: adults who became active later still saw meaningful 5–10% improvements. The decline starts earlier than people think, and the body still adapts later than people assume.

The Enhanced Games are heading to Las Vegas — performance-enhancing drugs under medical supervision, openly. We get into what it signals about hormone optimization, peptides, and biohacking moving mainstream, and where the line between elite sport and openly enhanced spectacle is going.

Quick hits include Jake's 20:38 finish at the Stony 100-miler (400 laps around a track), an 80-year-old shaving three hours off his Badwater time three years after a DNF, William Goodge running the Los Caños de Florida 100, Hunter McIntyre's man camps and the case for mentorship in fitness culture, Farm Fitness in the UK building a HYROX-first community gym model, Dr. Riccardo Ceccarelli's mental performance labs training F1 drivers and tennis pros for "mental economy," and Whoop rolling out telehealth visits and AI features as wearables move from tracking to platform.

Study of the Week: a systematic review and network meta-analysis in Frontiers in Public Health — 29 randomized controlled trials, 1,300 middle-aged and older adults — comparing aerobic and resistance training intensities for glycemic control and cardiorespiratory fitness. The takeaway: resistance training is metabolic training. Muscle is where your body decides what to do with glucose, and strength work moves the needle on HbA1c and fasting glucose in ways most people never connect to the weight room.

In Episode 3, we cover Fergus Crawley’s Project TENacity, where he is taking on 10 Ironman-distance triathlons in 10 days across 10 cities to raise money for mental health through CALM.

We also break down the latest from Cocodona 250, including Rachel Entrekin’s overall win, Courtney Dauwalter’s rebound, Killian Jornet’s men’s course record, and updates on Max Jolliffe, Cam Hanes, and Sally McRae.

Plus, we talk sodium bicarbonate for performance, wild strength and endurance stories, wellness festivals, Google’s new Fitbit Air, AI health coaching, and the rise of screenless wearables.

The main deep dive is David Sinclair and Life Biosciences' partial epigenetic reprogramming therapy, which the FDA cleared for the first in human trials in January 2026 starting with the eyes. We explain what partial reprogramming actually is, why the Yamanaka factors matter, why the eye is the place to start for this kind of work, and what the real risks and limitations of this approach are.

We also discuss three new studies that hit the timeline this week. A Nature Communications paper on whether rebound sleep can offset the mortality risks of poor sleep, a Journal of the American College of Surgeons review that showed prehabilitation before surgery cuts postoperative complications by 48%, and a year-long randomized trial in the Journal of Sport and Health Science finding that aerobic exercise lowers long-term cortisol levels.

In athletes and races, we review Sebastian Sawe's sub-2-hour marathon at the 2026 London Marathon, the HYROX Warsaw Major where both men's and women's Elite 15 world records fell in the same weekend, Matthew Johnson's 7 Ironmans in 7 days, and Jason Gay's Wall Street Journal article on whether the sub-2 breakthrough was because of the shoes or the carbs, with a further look at race fueling from David Roche, Courtney Dauwalter, Kris Jones, and Eliud Kipchoge.

Quick hits include Chris Williamson's Neutonic, WHOOP's new sleep variability research, EMFs affect on children, Consistent habits and measurable changes from Gary Brecka, and the debate on how much you should be relying on wearable sleep data.

The main deep dive is the FDA’s upcoming review of several popular peptides and what that could mean for compounding pharmacies, wellness clinics, and the future of regulated access. We explain what peptides are, why compounds like BPC-157, TB-500, MOTS-C, Semax, KPV, and Epitalon have become popular in fitness and longevity culture, and why the evidence and safety questions still matter.

We also discuss Oura’s acquisition of Galen AI and the push toward wearables becoming personal health intelligence platforms that connect biometric data with labs, medications, and medical history.

In athletes and races, we break down John Korir’s Boston Marathon course record, the upcoming Cocodona 250, the 2026 G.1.M Ultra, Mike Egan’s inspiring performance, Kristian Blummenfelt’s IRONMAN Texas win, and a look back at the San Francisco T100 sprint finish.

Quick hits include WHOOP, Will Ahmed, Prophetic’s lucid dreaming headbands, and Hunter McIntyre on sled friction.
