While feeling the burn during a workout is generally a good sign, feeling the burn while sitting on the sofa means your sofa is in the fireplace. Engage in controlled, constructive body burning with today's Groupon: for $25, you get one month of unlimited access (a $59 value) at Studio Fitness on Schillinger Road.

Studio Fitness' women-only group workouts motivate gym-goers with proven programs and a supportive atmosphere. The extensive array of classes tackle all aspects of health with group programs including four Les Mills classes, which throw heart rates into overdrive in more than 13,000 clubs worldwide. Les Mills BodyCombat unleashes dormant punching, kicking, and striking muscles in a martial-arts-inspired experience, and the 60-minute BodyPump class lets get-fitters choose their own weights before squatting, pressing, and curling all major muscle groups. The BodyStep session energizes participants with simple cardio movements, driving beats, and the overpowering drive to stomp cardio blocks with some jazzy footwork, and the indoor cycling RPM class tackles simulated race courses over varied leg-strengthening simulated terrain.

Along with the popular Les Mills programs, Studio Fitness' schedule showcases Zumba—a Latin-infused dance workout—as well as spinning, Pilates, and yoga classes. An organized, modern, judgment-free atmosphere and free childcare for all members obliterate any last lingering desires to become one with the sofa.
