## Summary

In Norwegians tracked for over 30 years, those who stayed active from middle age into their 70s had 78% lower odds of confirmed muscle loss. Even people who started exercising later in life saw meaningful benefits. People who became inactive lost most of the protection.

## Practical Takeaway

This study suggests starting or maintaining regular activity at any adult age may protect against age-related muscle loss.
