Haunches-in, also called travers or tête au mur ("head to the wall" in French), is a lateral movement used in the dressage discipline of horse training.
It has a close cousin, haunches-out, renvers, or croupe au mur ("rump to the wall"), that is slightly more difficult.
Both movements are four-track, meaning they produce four lines of hoof prints in the sand, as opposed to the usual two seen if the horse is straight and to the three-track shoulder-in.
Additionally, travers is a stepping stone to the more advanced half-pass,[1] and goes together with the turn on the haunches, which also asks the horse to move in the direction of bend.
It is employed by the Spanish Riding School, due to their belief that travers encourages the horse to travel crookedly with their haunches leaning toward the center of the arena.
The rider's inside leg asks the horse to bend in the direction of movement and to maintain forward motion and rhythm.
