The word comes from the Greek 'gymnos' which means 'naked'. In antiquity this was how young Greeks maintained good physical condition. From physical discipline it became a military discipline and gymnastics were used in the military training of men between two wars, designed to give them strength. There are six events for men: floor exercise, rings, vault, pommel horse, horizontal bar, parallel bars, and four for women: vault, uneven bars, balance beam and floor exercise. The basics of gymnastics have not changed much, but they are becoming much more spectacular in form. The only change to the rules is that floor exercise, which was more the prerogative of women has now become an event for men as well.
