Why are you losing muscle as you age (and how to stop it) with Dr. Gabrielle Lyon

What if the key to living longer isn’t simply adding more years to your life, but building the strength to stay capable throughout them? In the premiere episode of Strength Required, presented by Ladder, Ladder Co-Founder and President Tom Digan sits down with physician and muscle health expert Dr. Gabrielle Lyon, alongside Ladder Coach Lauren Kanski, for a conversation about why skeletal muscle matters far beyond aesthetics and athletic performance. Dr. Lyon explains why she considers muscle an essential organ system and why building and maintaining healthy muscle can influence metabolic health, independence, body composition, and how we age. They unpack the difference between lifespan and “muscle span,” why strength training becomes increasingly important with age, and why walking alone doesn’t provide the same stimulus as resistance training. The conversation gets practical as Tom and Lauren bring in some of the most common questions from the Ladder community. Dr. Lyon breaks down protein intake, essential amino acids, protein quality and meal timing, including why she believes protein should remain a priority whether your goal is losing body fat or gaining lean mass. They also discuss GLP-1 medications and the importance of protecting muscle during weight loss, the changing conversation around hormones and perimenopause, and why women shouldn’t shy away from challenging resistance training as they age. Finally, the conversation moves beyond physical strength into the “inner game.” Dr. Lyon shares why she focuses on standards rather than goals, how to stay consistent when life gets difficult, and the personal experience that taught her what strength means outside of the gym.
