Of the two horses I ride, I can only ride cstirrupless for a few minutes (like 3 mins) before the sensitive one gets upset by my legs hanging too low, and the four year old just can't figure out what I want and gets frustrated. Two pointing I can do more of, but the four year likes to be heavy on the forehand, so me two pointing just makes it worse. For this reason I prefer not too on him. My other horse doesn't mind, but I only ride him one or two times a week to school him up for my parents. I can only spend a few minutes working on my leg because I need to work on him.
What excersises can I do on the flat to help me without hindering the horse? Should I just forgo my horses work to get my leg better?
Here's video that shows my legs pretty well, you can really see it come off his sides when I post and swing at the canter. No critiquing anything else though, we've both improved greatly in the last month
