I'm new to the HorseForum. I'm riding a wonderful dressage horse. I'm only a lesson person right now and no longer own a horse (for now, that is) This horse is a terrific schoolmaster but well, I'm having trouble sitting to that big trot. My position has vastly improved, the canter is no problem and transitions are pretty good but my seat is just not as quiet and steady as I'd like it to be. We've been working without stirrups and on the lounge line too. He is very powerful from behind (love that!). How long did it take some of you?I'm been trying very hard to get my core up too. Suggestions?
