Inside each Sky Zone location, a wall-to-wall half-pipe made entirely of trampolines gives children and adults a venue where they can safely hop, bounce, and somersault to their hearts' content. Visitors can meander along the bounceable terrain in the open trampoline arena, throw themselves into giant foam pits, or sharpen their competitive edges in trampoline-assisted sports such as dodgeball. SkyRobics classes merge gravity-defying fun with fitness during instructor-led workouts that include calisthenics, core exercises, and strength-building aerobics to help guests shed calories without hurting their joints or taking a wrong turn on a treadmill.
