Thanks for the replies!
I'm aware of Gracie being behind the bit, and she's not a hot horse so I was expecting someone mentioning that she needs more impulsion. As for the forced head set, I don't think that's what my trainer is focusing on if it appears she is. Gracie is unbalanced, (a lot more so two weeks ago- I feel a huge difference in her gaits) and we've been focusing on outside aids with inside aids for flexion, and to keep her from falling in. We also try to entice her to use her back and not be (all strung out like) a "banana", if you've heard that imagery before.
Today I rode her for the entire lesson, (I can't remember if I mentioned that my trainer usually warms her up) and we worked over poles and cross rails at the end. (There's a schooling jumper show on Sunday and I'm taking her in the 12'' class ;3) Oh, and I forgot to mention, when Gracie first came to my barn a few months ago, the lady I bought her from, (aka another trainer) solidly rode her in draw reins for the first couple weeks of her re-training. Could this be another reason for her being over the bit?
