In this episode of the Stronger By Science Podcast, Greg and Eric split the “Feats of Strength” duties, then take a deep dive into some research on how sleep affects performance and body composition.

Greg and Eric also interview Dr. Brandon Roberts, who tells us about his current bodybuilding prep, why some people respond better to training than others, and why sleep is so important for lifters.
