===Choreography===
Many instructors will prepare a set of moves that will be executed together to form the choreography of the class.  Usually, the choreography will be timed to 32 beats in a set, ideally switching legs so that the set can be repeated in a mirrored fashion.  A set may consist of many different moves and the different moves may have different durations.  For example, a basic step as described above takes 4 beats (for the 4 steps the person takes).  Similarly, the "knee up" move also takes 4 beats.  Another common move, the repeater knee, is an 8-beat move.

Classes vary in the level of choreography. Basic level classes will tend to have a series of relatively basic moves strung together into a sequence. More advanced classes incorporate dance elements such as turns, mambos, and stomps. These elements are put together into 2–3 routines in each class. One learns the routines during the class and then all are performed at the end of the class. Regardless of the complexity of the choreography, most instructors offer various options for different levels of intensity/dance ability while teaching the routines.
