There are a few ways to interpret your question, the answers so far are indicating — many people may confuse dance choreography, which has complicated sequences with a planned class. Also freestyle can work if you are an expert communicator and know how to queue effectively. However, I find the participants in the class determine which approach is most effective. My clients say they prefer to take a class that has some set standard that they can follow in order to get a good workout (is that choreography?). Otherwise, they spend the entire class trying to figure out what to do. At the same time, the attendees have also told me that if they wanted to take dance lessons, they’d go to Zumba or Fred Astaire instead of to the fitness center. I think it’s best to do what’s right for the members over your personal preference as an instructor. A professional group fitness instructor adapts to every situation and brings the best of his or her training and experience to every class.
