At a barn I used to go to, my old instructor had me do some no stirrup work. She'd have me take one foot out of the stirrup and post with one foot in the stirrup, do a sitting trot without stirrups, and do a posting trot without stirrups.
I rode a horse with a very bouncy trot. What is the best way to sit a sitting trot and not bounce around on a horse with a very bouncy trot? Also is there any correct way to post without stirrups? My old instructor would tell me not to squeeze with my knees.
