Ok so the new mare I'm leasing is quite tricky haha. I've ridden her now about 8 times and have noticed turninh to the right she is incredibly bendy almost too much to where she rubber necks if you aren't paying attention to her. Now to the left is a whole nother story she will not bend she flexs somewhat but again stiffer to that side in fact she turns her head, or atleast tries to, to the outside of the circle. I use my left leg to keep her shoulder up and just hold tge left rein with some tension and give her her head the second she gives even a little bend but I was wondering if anyone has any other good exercises other then circles. She is green she is 6 yrs old and had 90 days back as a 4 yr old I believe but then the lady let her daughter just run her up and down the pasture till the current lady bought her and has used her as a trail horse.
