We shouldn't run our bodies through a CrossFit WOD without proper movement prep and body maintenance. In the photo above our athletes are rolling around on tennis balls. Working on loosening up some gristle. Gristle is bound up muscle tissue that requires some focused attention. The idea being that anywhere you can find a spot that "sings" when you roll over it, you need to focus in and work it out. If this doesn't make sense to you, ask your coach.
