Lunge

A piece of training/safety equipment which attaches the belt (worn by the performer) to ropes that run up through pulleys and down to a trainer. The trainer holds the lines (ropes) to assist the performer with new or dangerous skills. When the performer is more confident with the skill a single line can be attached instead of double lines. A Lunge is also a gymnastic/yoga term, involving both feet on the ground, with one leg straight and one leg bent.
