At Final Results Fitness, patrons tone torsos in small-group classes led by skilled trainers utilizing close individualized attention and unconventional equipment. In one of four gym studios, a kettlebell trainer steels groups of 6–10 students, who hoist round weights in exercises that build strength and stamina and ready students for high-octane handbell recitals. In outdoor boot camp sessions, instructors drill bodies with pushups, jumping jacks, mountain climbs, and half-mile runs. Nimble feet jump on and over plyometric boxes while tenacious arms pull ropes and spar with sentient monster trucks. After air-horning metabolisms awaken in the 30-minute kettlebell or boot camp classes, nutrient-needy bodies can recover at the Juice Joint, where staff members concoct smoothies made with 100% crushed fruit and no added sugars or high-fructose corn syrup.
