The word, “lateral,” defined by Webster as “pertaining to the side,” has two applications in hunter seat riding. “Lateral aids” refers to the use of the rider’s aids on the same side of the horse, such as the right leg and right hand. This is opposed to “diagonal aids,” which are applied on opposite sides of the horse, such as the right leg and left hand.

“Lateral movements,” however, refers to any suppling exercises which are used to lessen the horse’s stiffness from side to side. They range from the simple circle to more difficult movements such as the modified pirouette or half-pass. Even bending a horse around the corners of a ring can be said to be a lateral exercise, for it affects the animal’s suppleness from side to side.

There are two basic leg positions used in flatwork. The first, referred to as “at the girth,” is the placement of the rider’s calf against the horse’s flesh just behind the back edge of the girth. This position is used both to bend the horse and drive it forward.

The second leg position is referred to as “behind the girth,” which is about four inches farther back than the first. This position affects the lateral, or sideways, movement of the horse’s haunches and is also used to drive the horse forward.
