I'm really finding it a challenge to keep my hands quiet at the rising trot. I know that they need to be quiet, and it is better than it was, but I think I am still bounding them too much. When I come up, they come up. They don't come up as much as they used to, but they're still coming up. If I try to force them down it does weird things to the rest of my posture (I think doing this may be creating tension through my upper back, possibly some other undesirable effects as well).
My lesson horse has pretty big movement. I noticed when I recently rode a smaller horse with a shorter trot that I was better able to keep my hands near his mane throughout...but that horse was small enough that I didn't feel like I could get a good leg on him (I felt like with a good stretch I'd be able to rub my feet together). So the bigger horse with the bigger movement it is.
I'm at the point now where not being able to keep my hands quiet is limiting the horses I can ride, so I'm grateful for any suggestions on this!
