Unfortunately I don't have any pictures or videos, so I will do my best to describe my riding and what I need help with. My riding is very important because I am training for my B.H.S Exams, and riding is part of the exam.
When posting to the trot, apparently I arch my back and therefore rise onto the cantle of the saddle, instead of rising and sitting in the middle, and therefore under myself. I can feel myself doing it, and despite me trying my best to rectify the problem, I can't seem to!
When trotting without stirrups (which I will have to do in my exams) I end up sitting on my *ladies region* instead of my butt. This results in me stiffening up, bouncing everywhere and therefore looking terrible! I try hard to get my but underneath myself and sit properly, but I am finding it so hard.
I am working with an instructor but I just wanted to see what ideas you guys had. I need to get these problems sorted so I can start focusing on other things for my riding section.
