The Claim

Resistance training is associated with increased muscle hypertrophy and strength gains in healthy adults, likely through mechanisms including elevated muscle protein synthesis and myokine release, which support structural and functional adaptations in skeletal muscle.

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 people build bigger, stronger muscles, probably because it makes their muscles produce more protein and release helpful signaling molecules that help them grow and work better.

What the research says

1 study
  1. Study: Strength Through Science: A Comprehensive Look at Resistance Training and Protein Intake in Muscle Development

    This study shows that lifting weights makes muscles bigger and stronger by triggering natural processes in the body, like making more muscle protein and releasing helpful signaling chemicals — just like the claim says.
