When your muscles get bigger from lifting weights, tiny repair cells called satellite cells stick themselves onto muscle fibers to give them extra nuclei—like adding more workers to a factory—so the muscle can keep growing big and strong.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Evidence from Studies

Supporting (1)

1

The study says that when muscles are worked hard over time, special cells called satellite cells help them grow bigger by adding new nuclei inside muscle fibers — which is exactly what the claim says.
