Muscle mass is our metabolic armor. Sarcopenia (age-related muscle loss) and osteopenia are directly linked to metabolic dysfunction, insulin resistance, and catastrophic frailty in later decades.
Engaging in progressive resistance training 3 to 4 times weekly stimulates mechanical tension pathways, preserves bone mineral density, and increases peripheral insulin sensitivity. Grip strength and leg press power remain among the single strongest biological predictors of longevity and functional independence.
Focusing on multi-joint compound movements (squats, deadlifts, presses, and pull-ups) maximizes neuromuscular recruitment and anabolic hormone signaling.
