Inside each Sky Zone location, a wall-to-wall half-pipe made entirely of trampolines gives children and adults a venue where they can hop, bounce, and somersault to their hearts' content. The vast, taut, springy flooring doesn't end at the walls, but instead the trampolines continue upward to form angles perfect for springing off. 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.
