^ started from the ground and worked my way up, of course. I've done it before with great results. All about the timing. You put the pressure on and the moment the horse gives you the response you want, you release. Magic will give laterally and vertically and didn't need to be taught reinback - it was just a result of the mouthing work that I did. She has a very soft mouth. I started with a full cheek snaffle, and she is now in a D-ring.
