Today we are doing a scientific deep-dive into the mechanisms of muscle building and how to optimize muscle building in the least amount of time. Joining us to share his knowledge on the topic is Dr. Jeremy Loenneke, who talks to us about what happens when a muscle is lifted, what triggers and blunts the muscle-building response, and how we can maximize muscle building. For him, rest and recovery between workouts are vital in building muscle, and he shares around the overemphasis on constant training in our contemporary fitness culture. We shift to talking about the latest developments in the blood flow restriction space and Dr. Loenneke explains the relationship between blood flow restriction and muscle gains. What emerges strongly from our conversation is the care that should be taken in scientific research, especially as it pertains to random error. Sometimes the muscle-building discrepancies that are observed among different people are not as clear-cut as research shows — there are variables and random noise that affect outcomes. Join us to also hear more about myokines, the role of cortisol and antioxidants in muscle gains, incorporating fast and slow-twitch training, genetic factors, and the exciting studies they are currently working on.
