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.

The Erics sit down with bone health expert Dr. Lora Giangregorio, a professor of kinesiology at the University of Waterloo, to unpack what's actually known about how bone adapts to resistance training. The conversation covers why bone changes so slowly, the many sources of measurement error in DEXA scans, and why so much of the exercise-and-bone literature is underpowered and hard to interpret. Dr. G makes a central practical case: for building bone, the message shouldn't be "lift heavy" but rather "work hard." Emphasizing high effort over intimidating absolute loads lowers the barrier to entry, especially for older and osteoporotic populations, while still driving progressive overload. She argues the best current bet is combining moderate-to-high-intensity resistance training with impact work, introduced gradually on a foundation of strength. Along the way she debunks popular but weakly supported interventions, including weighted vests and whole-body vibration platforms, and discusses the difference between biological aging and simple chronic inactivity in bone loss.
