Eventing, show jumping and dressage, described under "Olympic disciplines," above are all "English" riding disciplines that in North America sometimes are loosely classified within the "hunt seat" category. Saddle seat, is a primarily American discipline, though has recently become somewhat popular in South Africa, was created to show to best advantage the animated movement of high-stepping and gaited breeds such as the American Saddlebred and the Tennessee Walker. Arabians and Morgans may also be shown saddle seat in the United States. There are usually three basic divisions. Park divisions are for the horses with the highest action. Pleasure divisions still emphasis animated action, but to a lesser degree, with manners ranking over animation. Plantation or Country divisions have the least amount of animation (in some breeds, the horses are flat-shod) and the greatest emphasis on manners.

Bitless headstalls are also seen, such as a bosal-style hackamore on youger horses, or various styles of mechanical hackamore. In Vaquero style training, a combination of a bosal and bit, called a "two-rein," is used at some stages of training. The standard western bridle lacks
