Im trying to teach my mustang gelding how to do flying lead changes. He's catching the front legs very regularly but he hasnt caught a change in his back legs yet. I know this is due to his hips not being pushed inside like they should be. He understands how to move his shoulders independently and side pass but he has a LOT of trouble understanding how to move his hips independently. Right now im asking him to move his hips over by putting pressure farther back. He sometimes takes this as a sidepass cue and trys to do so and when he does I turn his head to to the girth and it causing him to move his butt. Is this a good method or is there a better one?
