A human pyramid is an acrobatic formation of three or more people in which two or more people support a tier of higher people, who in turn may support other, higher tiers of people. People above the bottom tier may kneel or stand on the shoulders, backs or thighs of the people below them. Typically, the number of people in each tier is one greater than the tier immediately above it, resulting in a triangular structure reminiscent of the formation's namesake.

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.
