How Muscle Controls Aging, Metabolism, and Bone

Dr. Doug Lucas welcomes Dr. Gabrielle Lyon for a muscle-forward conversation on how skeletal muscle influences far more than strength or aesthetics—it’s a key driver of healthy aging, metabolic health, and bone resilience. Together, they break down the core idea behind “muscle-centric medicine,” why muscle matters for long-term independence, and how the right habits now can protect healthspan later.

They also unpack the practical basics that move the needle—protein, resistance training, and consistency—along with the mindset shifts that help people actually stick with the plan. Dr. Lyon shares a preview of strategies from The Forever Strong Playbook, aimed at building strength and durability at any age.
