The gymnast performs a choreographed routine from 60 to 80 seconds in length consisting of leaps, acrobatic skills, somersaults, turns and dance elements on a padded sprung beam. Apparatus norms set by the International Gymnastics Federation (used for Olympic and most elite competitions) specify the beam must be 125 cm (4' 1") high, 500 cm (16' 5") long, and 10 cm (4") wide.[6] The event requires in particular, balance, flexibility and strength.
