General gymnastics enables people of all ages and abilities to participate in performance groups of 6 to more than 150 athletes. They perform synchronized, choreographed routines. Troupes may be all one gender or mixed. There are no age divisions in general gymnastics. The largest general gymnastics exhibition is the quadrennial World Gymnaestrada which was first held in 1939.
Aerobic gymnastics
Aerobic gymnastics (formally Sport Aerobics) involves the performance of routines by individuals, pairs, trios or groups up to 6 people, emphasizing strength, flexibility, and aerobic fitness rather than acrobatic or balance skills. Routines are performed for all individuals on a 7x7m floor and also for 12–14 and 15–17 trios and mixed pairs. From 2009, all senior trios and mixed pairs were required to be on the larger floor (10x10m), all groups also perform on this floor. Routines generally last 60–90 seconds depending on age of participant and routine category.
