Welcome back to The Young Lab, where we break down the science behind internal health, performance, and regenerative longevity. In today’s episode, we’re tackling one of the most overlooked, yet absolutely essential, predictors of lifelong health and vitality: muscle.

You probably think of muscle in terms of strength or looks, but as Dr. Young reveals, muscle is so much more. It’s the body’s central metabolic engine, governing how you manage glucose, regulate inflammation, support brain function, and even how you age. We’ll explore why muscle mass and strength are tightly linked to longevity, what happens as we lose muscle with age, and why focusing on weight alone can be misleading. We’ll also get into practical, evidence-backed strategies: the best ways to train, fuel, and recover for long-term muscle health and why balancing strength and cardio matters at every age.

Whether you’re a lifelong athlete or just starting out, this episode arms you with the frameworks and science to build resilience and protect your future health. Stay tuned!
