I do a little backing at the end of each ride but thats about it. I did a little flexing with her when i started her but havent done much since.
She might need a bit of that each day. It's what some trainers should be doing versus bitting them up and tying them to the saddle for hours. Just do soft pulls each time and not very many to start. She might be tight in her neck from the smaller arena so would affect her balance.
New video! Her jog is really getting some where, and her lope has improved big time sense I last posted a video. After this part (which was our warm up), I worked on some roll backs and either trotting or loping away, and then going from trotting to a stop and then doing some backing, trotting off again. She rode really good today
