Ep 383 - Q&A: Imbalances, Fatigue, & REDs

In today's Q&A episode, the Erics work through a few listener questions. First they tackle upper/lower body imbalance — why lagging body parts usually call for improving training quality before adding volume, and why standout muscle groups can be maintained on surprisingly little work. Next is a long discussion on managing fatigue and exercise sequencing in high-frequency, non-traditional splits, including why the "48 hours between muscle groups" rule is more dogma than requirement and how to think about fatigue as continuous rather than categorical. The episode closes with a multifaceted question on REDs (relative energy deficiency in sport) — what it is, its warning signs, and the limits of what bloodwork can actually tell you.
