That sounds like good advice to me, but my mare is extremely in shape, she just gets really worked up at the lope. I'm pretty sure we have the trust built and she knows what I want from her, but she always seems to speed up and put that head up as soon as we come out of those little circles. We've been working on circles for a long time now (and have introduced other things like one-rein stops) and we still can't get out of them without immediately speeding up and throwing up that head again. Any advice for us?
