hi. I'm looking for some ideas for ground exercises to help loosen up a stiff horse (or some books with ideas for the same). My project horse, Abby, is a rescue who had some bad experiences, both physically and mentally. She is an incredibly willing and smart horse, but she is stiff in one of her hind legs, likes to go around with her head in the air, and keep herself bent in one direction/counter bend a lot of the time. (She actually usually looks much more sound at the trot than she does at the walk) She has been like this since they had her (around 3-4 years), has been checked by a vet and is not in pain. Since I have been working her (since November) she has gotten much sounder and definitely moves much easier when she is in constant work. Anyway, I did a centered riding clinic with her a couple of months ago and the woman gave me some ground exercises to do before riding to help loosen her up. They seem to really help her, so I am looking for some more exercises to do before/after riding to help loosen her muscles. I am particularly trying to get her to stretch out her hind leg, bend, and carry herself with her head down, so any exercises to loosen her and help with those will help me.
