At most horse-riding schools, beginners start out on what is called the lunge. The riding instructor stands in the centre, while the horse, carrying its student, trots around on the end of a lunge line. The instructor determines how fast the horse moves, and with which gait, leaving the student to concentrate on his or her own balance and movements. The instructor assists in mounting the horse and explains how to do it properly. The stirrups are then secured at the right length and the student is usually shown a few ways to hold on – typically using a strap attached to the front of the saddle.
