Kind: research · Impact: medium

## In brief

- A study published in Nature Medicine reports that resistance training preserves lean and muscle mass in people taking weight-loss medication.
- The Tirzepatide and Resistance Exercise (T-REx) study also found that resistance training increases strength in these participants.
- The reported study is described as the first to show these effects.

## Why it matters

People losing weight on GLP-1 drugs can lose muscle along with fat, which may affect function and strength, so evidence that resistance training helps keep muscle matters for patients and clinicians planning treatment.
