Well, I wasn't sure, but it seemed that there was some bobbing at the trot. But then, in some of the video she was going over the trot poles, and some not.
The other day I rode Z in his jump saddle for a few minutes ( I usually ride him in a dressage saddle) and it felt SO weird to me. So hard for me to find my balance. I felt like a total clutz, I could NOT keep a good trot nor stay balanced. Not that I am so great in a dressage saddle, but the jump saddle brought back to zero!
