The advantages of learning how to back a horse in an arc correctly are many. The smallest aspects of this maneuver, once understood from the horse’s point of view, will prepare both of you for any advanced maneuver that the two of you are physically capable of doing. More technically advanced maneuvers embody the essence of reciprocal feel and well-timed releases that combine readily in this exquisitely balanced dance. As mentioned earlier, in magnitude of importance, I know of no other maneuver that will prepare a horse and rider team better for a wide range of advanced skills they are likely to need in the future.
What's the big deal about riding bitless? Why should we ride bitless?
Riding bitless, especially starting horses bitless, helps you to improve subtle communication with the horse, and to not rely on the bit for "control".
The horse's mouth is very sensitive. If we can improve communication with the horse in ways other than through metal in his mouth, the communication and the relationship will be better. It makes us better horsemen.
