Ok so I wonder if someone might be able to give me some tips, so I've always had troubles sitting the trot for some reason. I've been lucky i've ridden a lot of horses with smooth trots and my instructor has always put me on horses with smooth quiet trots. But lately my instructor has started switching me to different horses and the one I rode tonight had a really springy trot and I just COULD NOT sit to it. I tried to sit up, move to the motion of the horse and relax but it just wasn't working for me. I took my stirrups away and tried and I stayed on fine but could feel myself bouncing and I don't know what to do about it. Any tips on exercises I could do? Because no matter how hard I try to sit up straight, move with the horse and relax my body it's just not working for me.
