Many students look forward to seeing the friends they have made in class, which further increases motivation. Another advantage is variety. Individual classes are designed to appeal to different types of people with different goals and interests. Finally, in a group exercise class taught by an experienced instructor you have the reassurance that you are getting a sound workout. The instructor can teach you proper technique and answer questions you may have about exercise.
Disadvantages Conforming to the class schedule can sometimes be a problem.
Work or family demands can make it difficult to attend classes at a certain time, and the particular class you wish to take may only be offered at one specific time. Some people may find classes too intense, the choreography too difficult, or become frustrated trying to learn new moves. If you have problems with your knees, aerobics may put too much stress on the joints, possibly causing you pain and injury. Where to Participate Aerobics programs are offered in many locations including fitness centers, YMCAs, schools, churches and corporations. Make sure they are well-cushioned and properly fitted.
