This week on The Colosseum, we cover the biggest stories in health, fitness, wellness, and human performance.
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.
What is The Colosseum | Health & Performance?
The Colosseum is a weekly show built on a simple idea: modern science has answered a lot of questions about how to train, eat, recover, and live well — and most people are still left guessing.
Each episode, hosts Tyler and Jayden break down the latest news across health, wellness, and fitness. Exercise science. Endurance sports. Health tech. Performance nutrition. Recovery and longevity. It's the kind of honest, curious conversation you'd have with a friend who reads the research so you don't have to.
Expect deep dives on science, research, and training for IRONMAN, HYROX, and ultra-endurance events. Conversations with or about athletes, coaches, founders, and researchers pushing the field forward. And honest conversations about the wellness trends shaping how people train, eat, and recover.
New episodes weekly. Part of The Colosseum — a modern health movement.
