"I never really work a horse for longer than four or five minutes [at a time.] I want to take a quick break, and then we go again. Any of you who’ve worked out know how much a break of 30 seconds can help. It gets some oxygen back into the muscles." ~ Steffen Peters
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.
"Don't take the tempo down without revving the engine." ~ Chris Bartle
