Michael Phelps Is Getting Some Awful Medical Advice (And Bruises Too)

Michael Phelps has been using "cupping" to prepare for his Olympic swim races. Cupping creates huge red bruises all over one's body, and proponents claim it somehow helps muscles relax. This is sheer nonsense. Cupping is quackery, and it has a genuine risk of real harm. Let's hope Michael Phelps and other athletes find a harmless alternative superstition to help them prepare for their future events.
