Is there an overarching term that designates people who are involved in physical fitness and therapeutic endeavors (includes athletes, physical therapy patients, gym-goers, and physical yoga practitioners)?
I think it might be exerciser, which can refer to "one who exercises" or "a machine that exercises".
Is it the repetition of the "er" sounds, or the vagueness of the designation–or both–that makes it such an awkward word?
Other terms that come to mind are anatomy, movement, and physical activist. Also this thread of "word for physical exercises" popped up.
