Acrobatic gymnastics is a competitive discipline of gymnastics 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 where the focus is on strength, poise and flexibility; a 'dynamic' routine which includes throws, somersaults and catches, and a 'combined' routine which includes elements from both balance and dynamic.

A castell is a human tower built traditionally at festivals in a part of Catalonia (Spain), now also found in the rest of Catalonia, in the Balearic islands and in the Valencian Community.
