I feel much better today, but Izzy was still very up and stiff going to the left. I think it's partly because she's stiff on her right side. When we go right, she stretches through her left side, but she's probably hollowing her left side just a bit. When we try to go left, she's stiff/sore, and doesn't want to stretch her left side.
At least, that's my opinion. I finally understand what a wonderful dressage clinician tried for years to drill into my head at least. She'd be thrilled, if a bit dismayed that it took me so long to get here.
There is probably more going on that I'm aware of. I know my equitation isn't what it once was, so now that we're working on refining the aids, things that I did that didn't matter now matter a lot. With that in mind, I'm on the schedule for a lesson next week, or sooner if someone else cancels. Cathy owes me a couple lessons anyways for working while she was out of town, so this should be good.
It's also possible that this is like Izzy's rearing on the lunge. We'd work through it, then it would come back, then we'd work through it, then it would come back... every time we worked through it, she understood a little more, and now she hasn't done it in quite a while. (Knock on wood.) At any rate, if she's not going forward, there is absolutely no point in trying to push her into jumping, so we're just waiting again. I was really hoping to get her started this fall, then let her have the winter off, then pick it up again next spring, but it's more important that she understand the basics well than that she can half do a bunch of advanced moves.
