Muscle: Your Longevity Organ
Muscle is medicine
After age 30, you lose 3-8% of muscle mass per decade (sarcopenia). Muscle isn't just for movement — it's an endocrine organ that secretes anti-aging molecules.
Myokines: muscle's secret weapon
When muscles contract, they release myokines — signaling molecules that reduce inflammation, improve insulin sensitivity, support brain health, and even fight cancer cells.

Grip strength predicts lifespan
Grip strength is one of the strongest single predictors of all-cause mortality. It correlates with total body muscle function and biological resilience.
Key Takeaway
Muscle is your longevity organ. Strength training 2-3x per week is non-negotiable for healthy aging — it reduces disease risk, protects your brain, and maintains independence.
