Well- it looks like rock climbing is more difficult than balancing on one of those cement parking blocks. (who makes those anyway, they must be millionaires.) Anyway, I did my rock climbing and got hurt. It seems the more body weight you are trying to climb with the more stress and strain it creates on your body. Who would have thunk it??? I was grasping for a hold and heard a huge pop in my right wrist. It hurts to the point where I can no longer hold little M in my right hand alone.One of my friends at work told me to exercise my wrist with a 2 pund dumble to strengthen all the muscles around the wrist. I hope it works
