Even tonight as she decided she could not leg yield left, she began to back up. I was instructed to continue to ask her to move off my left leg. She continued moving off my left leg while backing the length of the arena. Once we reached the rail she continued forward and we finished the exercise. By the time we were finished she was moving off my leg all the way across the arena, corner to corner.
We then moved to working on a circle. Asking Roxy to counter bend just a little bit and to bring her shoulders around. We would leg yield in on the circle with me keeping a very soft inside rein and supporting her on the outside one. She had some beautiful moments of relative straightness. What a great feeling!
