Other word: haunches-in. Just like renvers this is work on three tracks: the horse hindquarters are brought inside so that the outside foreleg creates one track. The inside foreleg and the outside hind leg create a second track and the inside hind leg creates the third track. The horse is bent in the direction of movement.
Tiple bar
Just like the oxer the triple bar is a spread fence consisting of of graduating heights. Tiple bars look difficult but most horse jump triple bar fairly easy.
