Please teach me how to teach flying changes!
Just like the title says, what are some techniques for training a horse to do flying changes?
Backstory: 5yr old WB mare. Pretty easy going and unflappable in most situations. She would do natural changes as a 3yr old out in the field. Now jumping small courses and learning the beginnings of collection. Conformationally NOT gifted with the best badonkadonk... If she had her way she would travel stretched out like a limo. We are working on this. Getting much better at the walk/trot and starting to get the concept at the canter. When we are jumping courses, she naturally lands on correct lead *maybe* 60% of the time. If she doesn't land on correct lead and I try to ask for, we are getting it around 25% of the time. I would like to improve these odds ;-) My trainer isn't too worried about it yet, says as she gets stronger she will get better.
I would just love some tips/suggestions on exercises and the concepts behind them so that I can be better about actively setting her up for success.
