In today's episode, Drs Trexler and Helms discuss a wide range of fitness topics including metabolic stress, "the pump," targeting the different heads of the biceps, individualising diets and supplement protocols, maximal rates of fat loss, blood flow restricted training, the philosophy of science, and much more!We had some technical issues while recording this episode live, but it's all fixed now with the wonders of editing. If you don't understand a couple of the jokes, they're referring to chaos that has been deleted.
