The Claim

In male participants undergoing high-force eccentric exercise of the elbow flexors, maximal isometric force can remain significantly reduced for up to 47 days, with some individuals experiencing up to 89% loss of strength immediately post-exercise and prolonged recovery beyond typical timelines, indicating that muscle function impairment can be severe and long-lasting in rare cases.

Description
1 study reviewed
In plain English

Some guys who do really intense bicep exercises can lose almost all their strength right after and take over a month and a half to fully recover — way longer than usual.

What the research says

1 study
  1. Study: Muscle function after exercise-induced muscle damage and rapid adaptation.

    The study looked at the same type of muscle exercise as in the claim, but found strength recovered within 10 days for everyone, not lasting for weeks or months like the claim says.
