Understanding the Impact of Epigenetics, Ep 9 (Podcast)

Breaking Muscle HQ

Real Athletes. Real Coaches. Real Knowledge.

Breaking Muscle Radio speaks with three top experts in the field of epigenetics - Shea Robison, Hayden-William Courtland, and Kevin Cann. Whether you are new to the topic or not, this podcast will expand your epigenetic horizons.


Look in any science magazines, health publications, or newspapers, and you'll see scores of articles about epigenetics. This is not surprising, as its a relatively new branch of research with long-lasting implications on how we eat, train, and live.



In this episode, these three world-class experts share their research, insight, and deepest thoughts on epigenetics with Managing Editor Becca Borawski Jenkins and Coach Chet Morjaria.
