Sports scientist Dr. Mike Israetel debunks fitness myths, reveals you can transform your body in under an hour a week, then opens up about steroids and childhood bullying.

Dr. Michael Israetel — A sports scientist with a PhD in sport physiology and co-founder of Renaissance Periodization (RP). He's a leading evidence-based voice on muscle building, fat loss, and hypertrophy training, known for no-nonsense fitness education on YouTube.
Dr. Mike Israetel lays out the science of building muscle and losing fat with minimal time investment, arguing most people drastically overestimate what's required. He covers the core training principles (specificity, overload, periodization), how muscle actually grows outside the gym, optimal protein and calorie strategy, and why diet dwarfs exercise for weight loss. He gives a candid breakdown of steroids, including the physical, sexual, and psychological side effects he personally experiences. The second half turns deeply personal, with Mike sharing childhood bullying trauma and how achievement became his way of healing, in a wide-ranging exchange with Bartlett about identity and self-worth.
