Who was the clinitian? Did the clinitian get on your horse at all?
I don't understand this - you pulling your reins down into your pelvic area, creates a stiff rider, and then creates a braced, stiff, on the muscle horse.
I've never seen a clinitian tell their students to pull the reins with such contact, and keep their hands near their crotch - that's baffling to me?
I went to this same clinic a few years ago, and then after fair had started taking lessons with a new trainer, Linda Mizwicki. (I think that's how you spell it.) I had told her what Adams tried to teach me, and she told me not to do it. Unfortunately, Linda had to move, so no more lessons from her. I really don't want to do these clinics, but I have to if I want to do jumping in fair.
The whole pulling the reins down to your pelvic area just didn't feel right to me, and it was hard to do because she also wanted me to lean VERY far back. Almost to where I could barely see the dang jump clearly over my horse's head!
Today, I jumped my mare bareback over a two small jumps, and she was completely fine. No rushing, just a nice trot the whole time. Maybe before, it was just because she was at a new place, and she was being a brat?
