Perspiration gets mischievous when cooped up inside the body, acting out by drenching armpits on first dates and disguising itself as tears during job interviews. Release disgruntled body water with today's Groupon: for $29, you get a one-month unlimited Zumba membership to World Fitness Studio in Monroe (a $59 value).

Headed by licensed Zumba instructor and professionally trained dancer Jordana Bell, World Fitness Studio keeps bodies in shape with a bevy of dance-based Zumba classes. Zumba workouts use high-energy Latin music and easy-to-follow dance steps to burn fat and increase heart rates without the repetitive nature of stationary bikes or giant hamster wheels. Standard and targeted Zumba classes are offered throughout the day, seven days a week—click here to see the schedule—facilitating booty-shaking sessions regardless of work hours. Today's deal entitles Zumbaers to attend as many classes as they like over the 30-day membership period, including Zumba Toning, in which students shake toning sticks like weighted maracas.

Sessions take place on an expansive, 5,000-square-foot dance floor with a high-quality, digital sound system. Brightly painted walls and colorful lights create a party atmosphere better than a life-size piñata of J. Edgar Hoover.
