What does it actually take to become a faster HYROX athlete?

Dr Charlie Davids joins us to explore the physiological demands of HYROX, combining his research in muscle physiology and strength training with his own experience competing in the sport.

The conversation examines why aerobic capacity provides the foundation for HYROX performance, how lactate threshold and critical speed influence race pacing, and why muscular endurance may become more important than maximal strength once athletes reach a sufficient strength level.

Charlie also shares findings from his research linking running speed at the second lactate threshold to HYROX performance, alongside practical approaches to periodization, station technique, and training under fatigue.

The episode also explores blood flow restriction training and its potential to improve muscular endurance and aerobic adaptations, while highlighting where more research is still needed to establish meaningful performance benefits.
