If backing doesn't build muscle then why does every trainer I speak to tell me to back Lily to build more muscle in her butt and gaskins? Not trying to start a fight just to get that clear. And I know it does cause leg problems. Just wanting to know why they say it does help create more muscle.

Backing can help define what muscle is already there. But at what cost? There are many trainers out there that will do whatever it takes to win, even if it might not be in the best interest of the horse.
