Although body-exchange programs mean no one ever has to stay in one meat suit for long, returning yours in bad condition means you forfeit your deposit. Keep your constitution in returnable condition with today's Groupon: for $30, you get a five-class punch card at Parkside Fitness in Coeur d'Alene, Idaho (a $60 value).

Overlooking the waters of Lake Coeur d'Alene, Parkside Fitness hosts a cross-pollinated collection of yoga and fitness classes for women and men that integrate Pilates, free weights, and dance. Bend and breathe through traditional yoga, hot-yoga, and Vinyasa-flow sessions, or delve deeper with Mind Body Bootcamp, where students perform high-intensity Pilates and yoga at the pace of one hand clapping. All classes are led by Parkside's experienced and motivating instructors in the zen-like atmosphere of a private boutique setting. Guests can add some spice to the calorie fire through the Latin-inspired dance moves of a Zumba sweat session or harness resistance from their own bodies to lengthen and tone muscles during the weight, band, and ball exercises in a Physique 55 class.

Parkside also specializes in prenatal yoga for expecting mothers as well as yoga classes for children aged 3–10, to ensure toddlers don't pull a muscle during temper tantrums. A full schedule of classes is available online, and Parkside recommends signing up for sessions in advance to guarantee a spot.
