Hypoxic Training: The Science of Getting Faster With Less Oxygen

Can training in low oxygen actually make you a faster runner without adding more training hours?

In this episode of The Endurance Lab, I speak with Dr. Barney Wainwright, Senior Research Fellow at Leeds Beckett University, about the science of hypoxic (altitude) training and why many elite endurance athletes now use it to break through performance plateaus.

We discuss how hypoxic training works, whether it actually improves sea-level performance, the physiological adaptations behind altitude training, and whether an altitude generator is worth the investment for recreational runners and cyclists.

If you've reached a plateau despite consistent training, this episode explains why hypoxic training may be one of the few remaining tools capable of producing meaningful physiological adaptations that traditional training cannot.
