The 150-Minute Myth, Training at the Wrong Time, Exercise at Work

The "150 minutes a week" rule might be a floor, not a finish line. This week is all about how much, when, and where you should actually be training. 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 600K, Fitness After 35, The Enhanced Era

This week in The Colosseum... 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.

Fergus's Project TENacity, Cocodona 250 Results, Google's Fitbit Air

Welcome The Colosseum the hub of health wellness, and performance. 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. New episodes every Wednesday at 6 AM. Follow The Colosseum: Instagram: @colosseum_media TikTok: @colosseum_media Youtube: @Colosseum_Media

Sinclair, Sleep Rebound, The Sub-2 Era

This week on The Colosseum... 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.

Peptides, Oura x Galen, Peak Human Performance

This week on The Colosseum, we cover the biggest stories in health, fitness, wellness, and endurance performance. 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.
