Muscle is one of the most powerful and most underestimated predictors of long-term health. Beyond appearance or athletic performance, skeletal muscle plays a direct role in metabolic function, insulin sensitivity, cardiovascular health, cognitive protection, and lifespan. This playlist covers the science of muscle mass and strength — how they decline with age, why that decline matters clinically, and the evidence-based strategies for building and preserving them throughout life. Topics include resistance training, VO2 max, zone 2 cardio, visceral fat, body composition, and the physiological relationship between physical fitness and longevity.
