Why does this community-oriented and challenge-focused modality seem to have such a possible darkish aspect? To know why, it’s price realizing just a little bit extra about rhabdo.

What’s rhabdomyolysis?

The particular situation that crops up linked to train is definitely known as exertional rhabdomyolysis (ER), “which is mainly a breakdown of skeletal muscle attributable to strenuous train or regular train below excessive circumstances,” says Scott Cheatham, PhD, DPT, CPT, a professor of kinesiology at California State College, Dominguez Hills.

Combining all three of these modalities is definitely an indicator of CrossFit, particularly in CrossFit challenges, such because the Murph exercise, the place you full a one-mile run, 100 pull-ups, 200 push-ups, 300 air squats, and one other one-mile run as quick as you’ll be able to. (That is the problem that the majority lately despatched a lady to the hospital.)
