Obviously, check the saddle fit, and make sure you're not pinching him while cinching it up.

If you have poles, those are great for ground work and riding.I really like setting up an L shape with 4 poles (set trotting width apart). You can walk forward through the L (either out the ends over the pole, or making the turn), or back through it like in a trail course. Then you can also walk or trot over the pairs of poles - one pair at a time, or making small circles that put you over both pairs.
