In today's episode TK and Lucas are continuing the series on Mark Sisson's 10 laws of the primal blueprints. Today's topic was sprinting. Sprinting is something that is massively misunderstood in modern society, it is an activity that humans were meant to do, but the way modern humans do it is actually causing a whole lot of damage. We hope that today's episode will inspire you to get out and sprint once in a while to maintain that primal physique.
