To most this isn't much of an accomplishment, but to me it's huge. I just started learning English riding about 6 weeks ago. We have also been trying to get my gelding to lose weight, but I noticed he has COMPLETELY lost his top line instead of his gut. I mentioned this in front of the trainers. So, while trotting yesterday, one of the trainers (not mine, mine was working with a crazed mare) shouted "make him collect, it will engage his top line." I must have had a confused look on my face because she halted me and showed me how to wiggle my hands (kind of rocking like) and he instantly collected. So afterwards, every time he raised his head, I had him collect.
She even got me to understand proper contact. I now have a lot more control. I noticed that different trainers teach me different things. I kind of like using different trainers every so often, a new perspective seems to help me out more.
