"When you are in Aqua Zumba, you are still doing Merengue, Salsa, Cumbia and Reggaeton but the movements will be different since you can't take the land moves and just put them in the water because of buoyancy and resistance. So we make the movements more effective by adjusting them a bit with tempo and that's what makes Aqua Zumba different from other aquatic classes," explained Bullard.

She says participants do not need to know how to swim to take an Aqua Zumba class, since those in attendance are in water that is approximately armpit deep. Participants generally keep their feet on the bottom of the pool as they dance and move through the water during the workout.

"The people who take this class come because they already take water classes," she said. "We also tend to drive a lot of people from the land classes to the aqua class, which means it's bringing a lot of new people into the water."

According to Bullard, people from Vermont, New Hampshire, Rhode Island, Massachusetts, Canada and Maine are already registered for the Zumba Basic 1 or Aqua Zumba certification classes in Orono.

"Zumba will be around for quite a while," she said. "It's not a trend, it's not a fad, it's only growing and will continue to grow. And I'm very fortunate to see its growth and popularity in other countries. It's crazy! You don't even have to speak the language; you get up and teach a class and they get it because Zumba is the same across the world," explained Bullard.
