Geejubs your a beast man. I like the single arm stuff.
My buddy Casey had a really bad knee, and when he went to sweeden to play ball, they tested his full body balance. They said that his hip flexors were overworking and a few other things. Basically he was off balance. They gave him a bunch of single leg exercises to start doing. He did them, and as he's told me, never had pain again. So he put me on it too. I'll have to get you all of them.
