Aside from my foot pain (see other thread), I've been intrigued by the possibility of competing in Crossfit games. They have a master's level for us older folks (I'm 50 years old). I'm an avid weight trainer and pretty athletic. I know double-unders are one of the skills you need to master, I used to be fantastic with those. Anyone compete in Crossfit? Is it worth pursuing or a waste of time?
