Alright, well I have a little issue :). When Thumper leans to the inside, I put more weight in my OUTSIDE seatbone, the weight comes off of my inside stirrup/heel, and I lean to the outside. I honestly don't know why I do it; I know that it will just make his leaning WORSE, but when I sink my weight evenly into both heels and sit up straight, I feel crazily off balance. Thumper is notorious for getting his riders off balance, but I've never had this problem until about a month ago. I'm planning on talking to my instructor the next time I see her, but I'm won't be seeing her until next Tuesday; I ride on my own most of the week, with a lesson once a week. And I've been pestering her with so many emails that I would feel horrible emailing her once again haha. Any advice on how to fix this would be great, thanks :).
