Is strength training worth it after 50?

Illustration for the guide: Is strength training worth it after 50?

Short answer

Yes. In a meta-analysis of 1,328 adults aged 50 and over, participants gained 1.1 kg of lean mass on average. More training volume was associated with larger gains.

After 50: on average 1.1 kg more lean mass after resistance training
  • 1.1 (95% CI: 0.9–1.2) change in lean mass, kg: lean mass

What the analysis shows

Peterson and colleagues pooled 49 studies in adults aged 50 and over. Higher-volume programmes went along with more lean mass. Older participants gained less on average; the analysis does not establish an ideal starting age.

How to use it

As a practical starting point, try two short full-body sessions a week with manageable loads. Choose exercises whose technique you know and progress gradually. Machines can simplify the movement.

Limits

The studies varied greatly, and not all were randomised. Lean mass is not only muscle. With existing conditions, check with a doctor before starting.
