Having good, symmetrical shoulder mobility can reduce injury risk while enhancing climbing performance. It’s pretty easy to understand why being super limited, or hypo-mobile, in your shoulders is a problem for climbers. What many people don’t consider, however, is that it’s equally important to not have too much shoulder mobility, or hyper-mobility. It’s a common misconception to think “the more mobility, the better!” But in fact, if you’re hypermobile, stretching is exactly what you don’t want to do.
