The other day in my lesson we do things such as going from extended canter on the long side of the arena to collective canter on the shorter side of the arena to start training him to slow down on demand... He was doing this sooo well; the problem came in when we were jumping
Over single jumps he would be fine and just speed up a little before and after the jump but then slow down again when I half halt but over sets of jumps such as triplets? Three jumps in a row ( sorry for my terminology, still learning so someone can correct if wrong thanks ) he would go over the first one and then he would go into an extended canter and I would try half halt but he just won't slow down and instead speeds up, then he kept ducking out to the right of the third one! Problem is which didn't help the situation and probably made him stress is that I started getting nervous and every time he speeds up I tend to lose my position and obviously then lose control. I tried to sqeeze a little with my right leg and half halt with my left hand but he was still ducking out and not slowing down :(... We finally stopped him ducking out but that was with the help of putting poles on the right side of the jump
Can anyone give advice on what was happening and how to solve it and possibly how to strengthen my position such as exercises I can do ect? My teacher is brilliant and knows what to do but sometimes it's nice to hear other peoples opinions and advice on what to do?
