The term BALANCE BEAM is a common apparatus used in gymnastics and other sports. It consists of a RAIL, usually made of wood or metal, that is supported by two posts. The athlete must stay on the beam while performing various movements, such as jumps, turns, and poses. TOE holds are used to help maintain balance, and agility is required to move quickly and accurately. The beam is usually 10 feet long and 4 inches wide, and its center is known as the KEEL. Balance beam events are part of many competitions, and the steadiest performance is usually rewarded. The term 'teeter-totter' is sometimes used to describe the balance beam.
