Emi and Kiefer, two of our resident experts on all things muscle, sit down to talk about hypertrophy. They describe what it is, how and why it happens, why it’s good to go through periods of hypertrophic training even if you’re an athlete focused on strength or performance. We decided at the beginning of the episode that the topic of hypertrophy, strength, and muscle building in general should be a series, so this is part 1 of that series! Part 2 will be out soon!
