Caffeine Genes, Brown Adipose Tissue, Concurrent Training, and Hangovers

In today’s episode, Greg and Eric share a little bit of good news, followed by a Feats of Strength segment. That’s followed by a Research Roundup segment discussing brand new research on the influence of genes on caffeine responses, recovery postures during high-intensity exercise, time-restricted feeding (intermittent fasting), and concurrent training (cardio + lifting). After that, Greg and Eric field some listener questions in a Q&A segment covering topics including cold exposure, the effects of race and ethnicity on body composition estimation, nutrition during deloads, and hangover prevention tips. Finally, Evan Peikon is featured in this week’s On The Rise segment, and a few off-topic questions are answered to play us out.
