Resistance training stimulates muscle protein synthesis and increases bone density through mechanical loading, directly combating sarcopenia (age-related muscle loss) and osteoporosis. Maintaining muscle mass is a cornerstone of metabolic health, improving insulin sensitivity, glucose disposal, and preserving functional independence, which are critical for extending healthspan.
Verdict
A non-negotiable pillar of any serious healthspan strategy.

Protocol
- Perform 2-4 full-body sessions per week, focusing on compound movements.
- Train major muscle groups to near-failure within the 5-15 repetition range.
- Incorporate progressive overload by gradually increasing weight, reps, or sets over time.
Flags
- Proper form is critical to prevent acute or chronic injury.
- Overtraining can lead to fatigue, injury, and diminished returns.
- Consult a physician before starting if you have pre-existing cardiovascular or orthopedic conditions.
- Adequate protein intake is necessary to support muscle protein synthesis and recovery.
