What Drives Muscle Growth & What Doesn't | Dr. Mike Roberts
Summary
Dr. Andy Galpin interviews Dr. Mike Roberts on the molecular mechanisms of muscle hypertrophy, emphasizing mechanical tension as the primary driver. They debunk myths that soreness or lactate accumulation are necessary for growth, clarifying that muscle expands by adding myofibrils, not enlarging existing ones. The discussion explores why individual responses vary, linking high responders to greater satellite cell activation and ribosome content rather than circulating testosterone levels.
