Mare and I have have kind of hit a brick wall with our leg yields, and nothing my instructor is telling me seems to help. I am hoping that somebody else can give me a different insight on things I might be able to try. She will cross over in front no problem under saddle and in hand, and she will side pass no problem, however when we do leg yield she kind of rushes towards the wall in a somewhat sideways manner crossing over in front, but letting her hind end come because it is attached. My instructor is having me either stop her and ask for side pass, then go back to asking for leg yield when she gets rushy, or tap her with my whip on her butt when the inside hind comes forward to encourage it to cross over instead. Neither seem effective in getting her to cross over behind except maybe one stride right as we reach the wall.
I think part of my problem is that my mare is super flexible through her neck and shoulders. She can do a perfect showmanship pivot for days. However, she is rather stiff through the rest of her body. She is more than willing to twist herself into a pretzel if it means she can avoid crossing over with the hind end.
Anybody have any other thoughts on what I can try?
