With more than 20,000 square feet of aerobic acreage, HealthTrack offers members a premier health-club experience. Begin the tour de fitness with a one-hour massage at the day spa (a $75 value), where a therapist will knead away knots and limber up muscles in preparation for an intense one-hour personal-training session (a $55 value). After equipping amateur exercisers with fit-focused survival skills, the trainer will free pupils into the vast expanse of workout options available to members. This Groupon entitles you to 14 days of membership after activation (a $90 value). HealthTrack offers top-tier equipment and more than 75 group classes each week, including cardio boxing, Pilates, spin, step, and competitive channel changing. Check the class schedule, or choose from a plethora of other sweat-breaking activities, such as basketball, swimming, tennis, running on the indoor track, or extreme relaxation in the gym's jacuzzi or sauna.
