A 2.8  cm thick steel or fiberglass bar raised 2.5 m above the landing area is all the gymnast has to hold onto as he performs giant swings or "giants" (forward or backward revolutions around the bar in the handstand position), release skills, twists, and changes of direction. By using all of the momentum from giants and then releasing at the proper point, enough height can be achieved for spectacular dismounts, such as a triple-back salto. Leather grips are usually used to help maintain a grip on the bar.
