"Evidence-based" bodybuilding peaking is somewhat of a misnomer, at least for all aspects of peaking at this stage of the game. Being able to construct a hypothesis based on physiology, is not the same as testing it. While we have empirical support that carb loading likely does enhance muscle size and appearance, the so-called "drying out" process that many bodybuilders partake in hasn't been studied, until recently. Join us in this episode as we discuss recent studies that assess the relationship between body water and bodybuilding success, and actually draw into question some traditional narratives."
