The Claim
High-resistance strength training is associated with increased muscular strength, which is linked to neurological adaptations such as improved muscle activation and coordination, as well as morphological changes including muscle fiber hypertrophy and satellite cell activity.
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.
Lifting heavy weights makes your muscles stronger, and that happens because your brain gets better at telling your muscles how to work together, and your muscle fibers themselves grow bigger with help from special repair cells.

What the research says
1 studyStudy: Morphological and Neurological Contributions to Increased Strength
This study shows that lifting heavy weights makes you stronger by helping your brain better tell your muscles to work harder and by making your muscle fibers grow bigger, which is exactly what the claim says.
