Do You Suffer From Dead Butt Syndrome?

There is apparently an ailment called “dead butt syndrome,” which, despite its amusing name, actually sounds quite painful. (It’s “an inflammation of the tendons in the gluteus medius, one of three large muscles that make up the butt.”) Fortunately, it only seems to strike serious runners, so, uh, I think I’m pretty safe. Add this to your “reasons not to work out” list.
