Releasing sweat is an effective way to lower body temperature, as is taking a cold shower or swallowing an igloo. Keep your physique regular with today's Groupon: for $32, you get a one-month membership, including aerobic classes, to World Gym Michiana in Mishawaka (a $65 value).

World Gym Michiana furnishes 20,000 square feet of open space with an arsenal of cardio and weight-training machines, complemented by a lineup of group aerobic classes. A one-month membership bequeaths full access to treadmill trekking, elliptical skiing, and iron pumping amid attention-diverting televisions. Meanwhile, cooperative cohorts can hobnob throughout fast-paced aerobic workouts, as certified trainers demand that exercisers wiggle, shake, and spontaneously hover to their hearts’ potential. After intensive training, clients can refuel with a vitamin-rich beverage from the juice bar (costs not included in today's Groupon), or meander to the locker room for a stint in the dry sauna or to intimidate showerheads with their rippling biceps. Housed inside the Town & Country Shopping Center, the family-owned-and-operated wellness epicenter sparkles with a meticulously clean interior and brims with line after line of well-maintained muscle machinery. Though only aerobic classes are included with this Groupon, members can also join one of the other fitness classes for an additional fee.
