"If you put a muscle where it doesn’t want to be, it is broken down – not build up."
So don't go thinking that you are building the right muscles when you force a horse's head into a position. The horse has to be using those muscles correctly to actually develop properly.
In the sport of Eventing, ensuring that our horses are truly fit for our level of competition is one of the best ways to prevent unnecessary injuries.
Horses become incapable of learning when they go past a certain level of fear, anxiety, or stress. This means that if you keep hammering away at the horse, trying to teach them something when they are currently overwhelmed with stress, it will not work.
For the horse, the learning happens on the release of the aid. That means if you don't release the aid, the horse will not learn.
