Acrobatic gymnastics is a competitive gymnastic discipline where partnerships of gymnasts work together and perform figures consisting of acrobatic moves, dance and tumbling, set to music. There are three types of routines; a 'balance' routine (at FIG grade 5 and above) where the focus is on strength, poise and flexibility; a 'dynamic' routine (also FIG grade 5 and above) which includes throws, somersaults and catches, and (at FIG grade 6 and above, as well as grade 4 and below) a 'combined' routine which includes elements from both balance and dynamic.
