Have you ever seen a cheetah run? A cheetah has managed to run up to 70 miles per hour, and uses its tail in a movement behind him in the arm for balance. While some horses are capable of reaching speeds of 50 miles per hour, not use their tails for balance, however, use your head and neck for balance.
When we ride a horse and try to get the collected and balanced, we are working to break free from the habit of using his head and neck for balance. We’re trying to move its center of balance from above his shoulder to the back of our head. Many horse trainers will focus on the importance of keeping your shoulders on the balls of your feet to maintain a driving position that allows the horse to transfer the center of balance.
As a rider helps balance the scales of your horse and you are targeting a perfect balance on your horse. To achieve this, would you rather be sitting on the horse in a way that you give the impression that you do not know much about him, and he can move as it wishes with great freedom.
If you move from a perfectly balanced approach to your horse by leaning slightly forward which puts more weight on the front of the horse, making it heavier and unbalanced. To compensate for this, he will transfer his weight to balance it so that it can do its job. The same problems arise when you lean back or side to side. This is one reason that instructors insist that you look straight ahead and not down when driving, which looks down changes your center of balance, and it moves forward. If you are out of balnc you really are the way of your horse and interfering with his ability to perform the tasks you want him.
