Acrobatic Gymnastics
Acrobatic gymnastics (formerly Sports Acrobatics), often referred to as acro if involed with the sport, acrobatic sports or simply sports acro, is a group gymnastic discipline for both men and women. Acrobats in groups of two, three and four perform routines with the heads, hands and feet of their partners. They may, subject to regulations (e.g. no lyrics), pick their own music.
In the US, beginning recreational acro gymnastics includes levels of 1, 2, and 3 (which require one routine containing both dynamic and balance skills). Compulsory levels 4, 5, 6, and 7 (which also only require one routine). At levels of 8, 9, two routines are required – one for balance and one for dynamic. For optional levels 10, and elite, three routines are required – one for balance, one for dynamic, and one combined routine.
