Though calories flee despairingly from the long lines of weight racks and cardio equipment that stretch across FitQuest Fitness’s expansive gym, a friendly staff escorts first-time guests on tours of the 10,000-square-foot facility and expansive hardwood fitness rooms. Independent-minded patrons can huff and puff their way through solo workouts on Magnum Fitness circuit-training machines or show off their biceps to dashing mirrored counterparts during free-weight curls. Hearts pump in communal harmony during more than 10 group fitness classes that blend muscle confusion to prevent plateauing, interval training, and quick intensity changes into a fat-busting cocktail. Students sweat out their inner children in 45-minute Fitness Toy Box classes that obliterate torpidity by way of sandbags, medicine balls, and resistance jack-in-the-boxes, and 60-minute Zumba classes melt away calories with fiery Latin dance moves. After the high-intensity presses, curls, and squats of the Get Pumped class, a relaxing hour of yoga can foster a frame of mind conducive to composing mature breakup letters to lovehandles.
