Specialized Fitness Classes are non-credit instructional programs and clinics and most options require pre-registration. These classes may meet only one time or weekly depending on the type of class or clinic. Weekly classes are taught by the same instructor at the same time each week. Weekly classes are usually progressive in nature, have a fee associated with it, and are instructed by a specialist in that activity. Classes taught may include, yoga, Pilates, martial arts based classes, fitness workshops, and various dance classes.
