The board is my horse. We're trying to get him into real working condition, and that of course means suppling him up. On his left side he's decent, he could use work, but he can turn his nose back to his shoulder no problem, and once he warms up, he yields his forequarter okay. Not fabulous, but he can do it. On his right side, he can't even turn his head around. He turns to the right by backing up to the left. He never ever picks up the right lead in the round pen or in turn out, probably because it's painful for him. We've had chiropractic work done before and he does have a lot of issues in his head/neck region, but really the only way that we're going to be able to work them out is having him worked on, and then following up with some consistent stretching exercises before each ride. He's already left sided enough as it is, so I want to do as much as I can to get him evened up muscularly, so we can move on in his training to working with his right side comfortably. What are some basic basic basic stretching/suppling exercises that we can do, either from the ground or in the saddle, or both?
