The Claim

Resistance exercise potently stimulates muscle protein synthesis and enhances the muscle-building response to nutrient intake, leading to a synergistic increase in muscle protein synthesis that serves as an effective countermeasure against disuse atrophy and age-related muscle loss.

What the research says

Roughly balanced

Support and challenge are close. The picture may shift as more studies come in.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Lifting weights helps your muscles grow, especially when you eat after exercising — together, they give your muscles a big boost and help prevent muscle loss from aging or not moving enough.

See the scientific wording

Resistance exercise is a potent stimulator of muscle protein synthesis (MPS) and enhances the muscle-building response to feeding, resulting in a synergistic increase in MPS that makes it an effective countermeasure against disuse atrophy and age-related muscle loss.

What the research says

1 study

  1. Study: Physiologic and molecular bases of muscle hypertrophy and atrophy: impact of resistance exercise on human skeletal muscle (protein and exercise dose effects).

    The study shows that lifting weights boosts muscle growth, especially when combined with eating protein, and helps prevent muscle loss as we age—exactly what the claim says.
