Lateral work can be used to steady and improve the regularity of the rhythm of your horse’s gaits. Particularly with horses that want to rush and/or become irregular, asking for a little shoulder in, leg yield, or a few steps of spiral in or out, can help them wait and find more cadence in their stride.
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.
