Part 4: The riders take the feel from the turn on the forehand exercise and begin to work on leg yield. Allison thoroughly explains the aids, and offers real-time correction and feedback, supporting each rider and their individual horses as they attempt the exercise. She reminds the riders of the importance of using their legs and not relying on the reins, and keeping one reins on either side of the horse's neck with an unbroken line to their mouth. Allison assists a rider with her rambunctious horse, and brings their focus back to quietness.
