My horse is dull in the dressage ring, what can I do?

Horses need variety in the training. Find a field and take him for a gallop, plan to hack him cross country at least once a week. The horse has a skeletal structure which is supported by many different muscle groups. The muscles used in play when in turn out, the muscles used to gallop, the muscles actived when climbing and descending hills and even other muscles developed in your training regine in the ring. The stronger your horse is all around, the easier his work is for him. More importantly he will enjoy the variety of doing different things.
