The Claim

The combination of resistance training and a high-protein diet is associated with greater muscle mass and strength outcomes than either intervention alone, suggesting a synergistic effect between mechanical loading and nutritional support.

In plain English

If you lift weights and eat lots of protein, you’ll likely build more muscle and get stronger than if you just do one or the other—because together, they work better than alone.
