Part 4: As one rider has a much better jump over the Liverpool, Leslie points out how the horse was tight behind and through his back at first, and how through repetition of the jump he has loosened up and is able to perform better. He explains the Liverpool is a fence that often comes down in competition, making it very important that both horse and rider get relaxed and comfortable with it in training. Leslie praises the use of voice aides which leads to a discussion of the other forward aides used in jumping.
