Hey Lia, a good exercise to help you: Set up a line of eight trotting poles on the ground, setting the standards to the outside of each pole so your horse won’t veer. The poles should be about 5 feet apart for an average-sized horse. If your horse is unfamiliar with trotting poles, walk him over them a few times first. When you and your horse are ready, trot the poles in both directions. You can ride in a posting trot or two-point jumping position.
Great training!
