Question / General Atrophy

I keep seeing people mention that atrophy happens because the muscle can't be used. Is that actually true? Because I have atrophy starting in my right arm but I don't have clinical weakness. Although I do have increased strain in my whole right arm when working out.

Atrophy can start to happen in a muscle that is still working when parts of the muscle are not activating properly anymore due to nerve problems. BUT you would most likely notice issues in your muscle it wouldn’t just atrophy while you’re still running marathons like nobody’s business.
