Thanks everyone. I have been learning about diagonals, I did know to rise to the outside leg but I don't always pick up on it when I get it wrong, especially when I'm concentrating on getting over the trot poles smoothly lol.
Thanks farmpony for the comment on my leg position, it could be because I have hardly ever ridden western before (once or twice), and also my trainer is good at explaining it. I do have a couple of photos where they slipped forward when trotting (when I was getting tired) but generally I'm ok at getting them to stay in the right spot
