Longeing (US English, classical spelling) or lungeing (UK English, informal USA) is a technique for training horses, where a horse is asked to work at the end of a long line and respond to commands from a handler on the ground who holds the line. It is also a critical component of the sport of equestrian vaulting. Longeing is performed on a large circle with the horse traveling around the outside edge of a real or imaginary ring with the trainer in the middle.
