It is a gymnastic modality that is practiced with various devices, such as the rack or the rings, or without them on a surface of regulatory measures.
A gymnast, whether in the male or female branch, must have special conditions related to flexibility, mobility, strength and muscular coordination. In 1896 it was included as an Olympic sport, although at that time it was practiced only by men.
Before starting, the gymnast should present his routine to be presented. The degree of difficulty must be validated by two judges. Subsequently, six more judges rate, on a scale of 1 to 10, various aspects of the performance and will punish and deduct points for errors, falls, errors in technique or composition.
