I am a very experienced rider and have been riding for 16 years. I have developed a little problem during my years. I have a very solid leg and steady hands all the time. My only problem is, is that when I pick up the canter I have a twist in body. My body does not stay still. I have tried almost everything to fix it, I have ridden without stirrups for months at a time. My trainer has told me to relax, pretend there is a metal rod up my back, etc. I was hoping you guys have some new ideas that I can try. A major problem is when I focus my attention on trying to stop my upper body movement I lose all focus and am not able to find any of my spots to my jumps, which is absolutely not acceptable. Please feel free to give me any new ideas that you might have in order to fix this.
