Last year in the University I've attended a riding classes and I was surprised by the behavior of the school horses under saddle. Each one of them found a way to shirk - one was just "lazy", another overreacted when asked to "work" (not just walk around the arena), some pushed against the bit... My favorite horse, Dyx, was very oversensitive, avoiding any contact on the bit (with his head held high or doing "self rollkur" to hide from the riders hand effect), doing very short steps, rushing and headshaking (no matter if the reins where loose or not).
I tried to do my best, but at the school stables horses work with a different rider each day and most of the riders are beginners... So please critique my riding and the changes in the horse during the lesson. (and sorry for the low quality photos, I have no better, and also sorry for the grammar mistakes - my English is not the best :))
