At Sound Fitness, one can almost hear the calories sizzle. Ample rows of bikes, ellipticals, and other cardio equipment let guests build strong, healthy hearts without feeling pressured to give up their machines to other guests or movie cops needing to commandeer treadmills. To propel exercisers toward their goals, certified personal trainers plot custom workout plans and demonstrate how to build specific muscle groups with the free weights and strength-training machines. Babysitters corral pintsize visitors while their parents jog and pedal, and shower-lined locker rooms keep watch over clothes and gym bags to make sure they don't wander home.
