Relax your back and seat, a tense back/seat makes a tense horse= hollow back, stiff poll. What I would do is ride him in 20 meter circles w/t/c. Hold the outside rein contact and lift your inside rein up and out a bit (about a 6 inches higher than you usually would, although every horse is different so play around with how high). Make sure not to let go of the outside rein when you do this. Every once in a while, counter bend him on the circle. Then try going down the longside after he has been flexing nicely and you have good contact, it should be better. Also try to move your hands with him, especially at the walk. You are also trying to get him to reach forward and downward so he accepts the bit, so think of allowing him to go through your seat, don't block him with your seat. Try and think of getting his ears as far away from you as possible, you can do this by holding your reins lower and out a bit and 'jiggling' on the reins so to speak, even during the circle exercise.
