Two months later and it feels like we have taken several steps back. He is very luggy on me, and always has his head above the bit or is trying to yank the reins out of my hands. He also doesn't move out as well as he use to. We are constantly in a tug of war when I am riding which I think is making the rest of me stiff which my trainer constantly yells at me about. When I try to relax to get him to relax and bring his head down he starts to speed up and I start to feel out of control, so I tighten up again so he goes back with his head sky high or lugging me on me again. When I ask him to stretch down he tries to grab the bit and yank the reins out of my hands. He also tries to do this dinky what I call his racehorse trot a lot more than he use to, I have to work really hard to get him to lengthen and with it usually comes a lot of speed.
Anyway, any words of advice or encouragement would be great, don't really have any horsey friends to talk to about this.
