It’s the start of a new era, as Omar and Eric sit down for episode 201. In this conversation, the two pick up where they left off from episode 200, tackling the Cult’s questions that were too good, and too deep to cover last week. Specifically, we discuss how to compare the potential effects of dissimilar variables on hypertrophy, such as sleep, protein, and creatine using research. Further, we field questions on how you measure progress and deal with plateaus, and whether higher frequency training can provide unique advantages.
