THE BRONX - Since 2001, Zumba classes have offered a fun way to sweat using a combination of dance styles, including Bollywood, salsa and pop music.

It is estimated that more than 14 million people participate in Zumba.

Classes don't involve any special equipment or skills.  Participants just follow the leader and go at their own pace.

The Parks Department offers a series of free Zumba classes.
