I've ridden him long enough that I know how to ride him fairly effectively, as in I can control him and have him respond to me. However, he lacks that nice long hunter frame. Since I'm working with him a lot more now (I volunteer at my barn in exchange for free rides), I want to learn to acheive that and perhaps one day show him.
I know that nice hunter frame comes with a lot of flexibility/bending. I'm working on that with him and he's getting better. But after that I'm not sure which direction to go in. So what do I do to achieve a good hunter frame with him?
