Dan and Adam reconnect after Adam's trip to the HYROX World Championships in Stockholm, where he was over with the HYROX Sports Science Advisory Council. They get into the NZ Muscle scandal and what it says about trusting your sports nutrition, the growing peptide and TRT conversation in the sport, and why HYROX is almost built for heat exhaustion. From there it turns into a full World Champs debrief: the men's race and the sled push that cooked Hunter, the lane-choice chaos, Alyssa's standout women's win, and Pelayo's comeback to the podium after an Achilles that was hanging on by a thread. They finish on where the sport is heading, why volume wins, HYROX Young Stars for kids, and the new Endurox Intelligence System.

Join Dr. Dan Plews, Dr. Adam Storey, and guest Sam Purchase in Episode 3 of The ENDUROX Podcast. In this episode, they break down force-velocity profiling — what it is, how to measure it without a lab, and how to use it to identify and fix the exact qualities holding back your HYROX performance. They also recap the Enhanced Games and why the whole thing was a bit of a flop.
They cover:
Sam Purchase: S&C coach, PhD researcher at AUT, and founder of Chase Health and PerformanceThe Enhanced Games: why performances underwhelmed, whether the doping protocols actually worked, and the swimsuit confoundForce and velocity: what the force-velocity profile actually measures and why it matters for power outputThe difference between the molecular force-velocity relationship and compound movement profilingForce dominant vs velocity dominant: what it looks like, what it means, and how to identify which you areApplying the profile to HYROX: which stations cluster together and whySam's master's research with professional rugby players: forwards vs backs and what the data showedHow Pierre Samozino's 2008 methodology made FV profiling accessible with a tape measure and a phoneSam's PhD research: three novel movements — bench pull, overhead press, and hip thrust — and why they matterThe propulsive phase explained: what it is and how to measure itTraining prescription from the profile: how to structure force or velocity blocks for a HYROX athleteContrast training and post-activation potentiation: the mechanism, the application, and where it fitsWhy max strength still matters for HYROX, and why the "it doesn't matter" narrative is wrongHow to periodise the FV profile into a full race buildSam's PhD data collection: how to get your profile tested at AUT MillenniumTimestamps:
