What does the term "posting" refer to in riding?

The term "posting" refers specifically to the action of rising and sitting in rhythm with the horse's trot. This technique is primarily used in English riding disciplines to help maintain balance and comfort for both the rider and the horse. When riders post, they alternate between standing up in the stirrups (rising) and sitting back down in the saddle, which allows them to move with the horse's natural rhythm during the trot. This movement helps absorb the impact of the horse's motion, making the ride smoother and more comfortable.

In contrast, riding without stirrups focuses on developing a rider's balance and seat but does not involve the rhythmic movement intrinsic to posting. Reining the horse pertains to steering or directing the horse, which is separate from the posting action. Jumping over obstacles involves a different set of techniques and skills that are not related to the posting method.
