Like a good horror movie, a good exercise regimen shocks the body out of its lethargy, which is why so many personal trainers chase their clients on treadmills while brandishing anacondas. Get in less terrified shape with today’s Groupon: for $25, you get a one-month gym membership (a $50 value) and a one-hour personal training session (a $75 value) at Body Masters (a $125 total value).

Body Masters’ personal trainers bestow exercisers with healthier alter egos, chiseling slimmer figures with open gym time, group classes, and personal training sessions. Improve cardiovascular health during a stationary jaunt on the FreeMotion strider or elliptical machines, or bolster biceps with a heave of the gym’s dumbbells, barbells, and replicas of the Liberty Bell. Held in a 1,000-square-foot training space replete with mats and accessories, group fitness classes such as Zumba, jiu-jitsu, and circuit conditioning deliver a physically rewarding social experience while confusing habit-averse muscles with ever-changing routines. Develop a personalized exercise program with your certified personal trainer, adjusting lifestyle choices while improving nutrition, toning core muscles, and ridding closets of all-denim gym wear.
