Static routines must present balanced pyramidal constructions held for 3 seconds and other elements of strength, flexibility and agility. Dynamic routines must present flight elements such as throws, pitches and catches as well as dynamic tumbling elements. Combined routines present elements from both the dynamic and the static routines.
