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 $79, you get a Zumba 20-class punch card (a $200 value) at Gold's Gym, with locations on McCarthy Boulevard North and on Pasqua Street.

With 7,000 members and counting, Gold's Gym presents exercisers with a smorgasbord of fitness classes, equipment, and services. Zumba classes introduce high-energy cardio exercise to Latin-inspired fast-paced music, creating an exhilarating full-body workout enjoyed by enthusiasts in more than 125 countries and three galaxies. Zumba's calorie-burning movements are easy to learn under the tutelage of one of Gold's seasoned trainers, and attendees are likely to further improve their moves after several classes. Schedules for both the North and South Gold's Gym locations offer several one-hour Zumba classes each week to help exercisers with non-Zumba responsibilities find the most convenient time to work out. Gold's Gym recommends Zumba participants bring along a towel, a water bottle, and a photograph of an ex to salsa-step on.
