On this episode of the Flex Diet Podcast, I chat with Dr. Mike Roberts, a full professor at Auburn University and head of the Nutri Bolt Applied and Molecular Physiology Lab. Mike’s one of the sharpest minds in muscle science, and we go deep into the nitty-gritty of hypertrophy, including everything from rodent studies to human trials to the molecular pathways that drive muscle growth.

We get into some serious geekery: ribosome biogenesis, muscle stem cells, the extracellular matrix — yeah, all the stuff happening behind the scenes when you train. Mike also shares his take on how HIIT and consistent resistance training impact muscle adaptation, and we riff on where nutrition fits into the equation.

If you're into the science of muscle or you're a coach looking to better understand the mechanisms behind hypertrophy, you’ll dig this one. Tons of actionable nuggets and some fascinating research.
