Zumba is a fitness program that combines Latin and international music with dance moves. Zumba as an aerobic exercise reduces health risks, keeps excess pounds at bay, strengthens your heart and boosts your mood. The high-energy classes are set to upbeat music and feature choreographed dance numbers that you might see in a nightclub. You don’t need to be a great dancer to feel welcome in a Zumba class. The classes emphasize moving to the music and having a good time.
