The trot, also known as the jog in western riding, is a two beat gait in which diagonally opposite hoofs strike the ground in succession. In a fast trot, the horse may extend its hoof in a particular "pointing" motion.
In the trot the diagonal legs must be raised from the ground simultaneously and be replaced on the ground together, making two hoof beats. A jump from one diagonal pair of legs to the other. A two beat tempo. For instance, after the left diagonal (right fore and left hind) leaves the ground, the right diagonal (right fore and left hind) is raised before the left diagonal has touched the ground again, so that the horse is suspended with all four legs in the air for a moment. This moment is called suspension.
The trot is a natural gait of the horse where the diagonal pairs of legs move forwards at the same time, a diagonal gait. There is a moment of suspension between each beat, as seen here http://lydielemmens.free.fr/images/Skazir_trot_suspension_texte_grand.JPG. The pioneering 19th century photographer Eadweard Muybridge was the first to prove this.
