It's called Zumba and it's a fitness program which incorporates Latin dance moves.

Although it's new to the north country, Zumba started in the mid-1990s in Columbia and has since really caught on.

It's now in 75 countries and over 40,000 locations, including the Watertown YMCA.

"It works because it's fun. You don't want to stop. The music keeps you going and you're just having fun and not realizing how much you are working out," said local instructor Angelica Robinson.

She is proof positive that Zumba is more than just a good time.

Robinson says she has lost 110 pounds in a little over a year.

"It's amazing and it's definitely an inspiration to me. I've struggled with my weight my whole life," said Jami Ramirez, a Zumba class member.

The Zumba motto is very inviting - "Ditch the workout. Join the party!"
