The word "endurance" is something that flies around pretty loosely. But what does it really mean? Can we really quantify endurance? Who needs it, really? Luckily, we have the one and only Dr. Matt Stevens to answer these questions. Matt is the founder of the recently launched "Pure Endurance", an online training platform designed for CrossFit and endurance athletes looking to be optimized in this realm. In episode #8 of "Pushing Downhill", Matt and Ryan discuss all things endurance. Programming, training and, perhaps most importantly, why endurance is needed for ALL athletes.
