I have recently joined Zumba. I attend classes on Thursday evenings for 1 hour. Zumba has became very popular through out New York City. When I visit Zumba.com I see they are every where. The classes are so much fun you dance to a mixture of pop, R&b, Reggae,salsa and everything else. The instructors are fantastic each week. The classes that I've attended is made up of all age group from pre teens to middle age women. We have 1 hour of none stop fun dancing mixed with aerobic. When I leave the classes and walk home I feel so energized and refresh.
