Zumba is a fitness program that combines Latin music and easy-to-follow dance moves. Zumba routines incorporate interval training, alternating fast and slow rhythms and resistance training. Zumba's fans say it's so popular because Zumba is a fun way to work out.

Some research indicates that dance-type aerobic workouts like Zumba can improve cardiopulmonary endurance when done at moderate intensity and duration. The bottom line is if you enjoy Zumba, you're more likely to stick with it — and more likely to enjoy the benefits of aerobic exercise.

As with any exercise, if a certain movement or position causes you pain, try to modify the workout to avoid the aggravating activities. And anytime you're training with resistance, remember that proper technique is key — don't get so caught up in the dance rhythm that you forget proper form.
