Muscle is the organ of longevity

Muscle mass is the #1 predictor of survival after age 50. It's not aesthetics — it's metabolic health, bone density, disease resistance, and functional autonomy.

Fundamental habits for hypertrophy

Strength training 3x/week minimum — progressive overload is non-negotiable.

1.6-2.2g protein/kg/day — distributed across 3-4 meals.

Sleep 7-8h — growth hormone is released primarily during deep sleep.

Creatine 5g/day — the supplement with the most evidence for strength and muscle mass.
