Does your horse’s canter need better rhythm? Try posting! That’s right, posting to the canter can help your horse relax his back, open up his stride and regulate his speed, all without touching his mouth. I use it sometimes with Freedom to open up his stride without having him get quick.
For the rider, posting to the canter can help you build your core strength and it’s a useful way to maintain your own rhythm when coming into a fence. In some regards I like it better than counting because you don’t anticipate the take off point.
Posting the canter can feel a little awkward when you first try it because, unlike the trot, the gait doesn’t naturally throw you up out of the tack. Stick with it and you’ll soon find that it’s not that hard and has some real benefits.
