How to build up his horse top line is a difficult question.
Clearly, the training program of the horse will matter a lot in the development of his muscles, and every horses’ needs are different. So I really advise you to talk with a professional who knows you horse such as a veterinarian or an osteopath so he will guide you through what is best for you horse.
In a general way, lunging the horse with his head low is a good way to stretch and build the muscles. I suggest hill work too if you have access to it. And of course a regular training is essential to maintain the shape.
