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 $20, you get one month of unlimited fitness classes at Windsor Squash & Fitness Club, located on McDougall Avenue (a $60 value).

Windsor Squash & Fitness Club adds oomph to squash-court pursuits with a host of group fitness classes held in a squeaky-clean, family-friendly facility. Clients can slay fitness goals with a one-three punch of cardio, strength training, and stretching in classes overseen by the club's professional staff. Good Morning Cycle and Spinergy sessions pair patrons with stationary cycles as they tackle hill climbs, interval training, and speed races against virtual paperboys, and each bike's easy modifiability allows riders of all stripes to adjust their own intensity and resistance levels throughout the workout. For a cardio and bulk-building blend, Xtreme Circuit clocks exercisers as they shift between strength- and cardio-based stations over a one-hour class. Kettlebell sessions bolster the body while fostering flexibility as students swing handled weights and volunteer pumpkins looking to make some extra cash. Windsor Squash & Fitness Club rounds out its full-body carte with a handful of relaxing, stretch-centric courses including Pilates, power yoga, and yoga for everybody, whose posework changes at a slower pace to accommodate all levels of mat-bound expertise.
