Why is strength training so important as we age?
Muscle is the organ of aging — twice-weekly strength training preserves function, independence, and metabolic health more than any pill.
After 30 we lose 3–8% of muscle per decade, accelerating after 60. Strength training two or three times a week reverses much of this loss at any age, reduces falls, improves how well your body responds to insulin (insulin sensitivity), protects bone, and lowers all-cause mortality. It is one of the highest-return interventions in medicine.
What is it?
Progressive resistance exercise using body weight, bands, or weights.
Why it matters
It is the single most important intervention for how you will move and live after 60.
Persian tradition
Persian zurkhaneh (house of strength) practiced disciplined body training as a spiritual and civic art.
Modern scientific evidence
Reduces all-cause mortality.
Preserves muscle and bone with aging.
Improves insulin sensitivity and mood.

- Twice weekly, 20–40 minutes.
- Cover legs, hips, back, chest, arms.
Safety
