In this episode of The Commune Podcast, Jeff welcomes back Dr. Gabrielle Lyon — physician, longevity expert, and author of The Forever Strong Playbook — to explore why skeletal muscle is the most overlooked organ in health and aging. They discuss the metabolic link between muscle and brain health, how to think about protein intake at any age, and why building strength safely over time matters more than just lifting heavier. Dr. Lyon also makes a compelling case for mindset as a core pillar of physical transformation. She shares practical ways to build mental toughness alongside muscle, from small daily friction exercises to doing hard things with your family. Today's episode is a grounded, actionable conversation for anyone ready to take their health seriously.
