Sky Zone, Portage

Inside each Sky Zone location, a wall-to-wall court system made entirely of trampolines gives children and adults a venue where they can safely hop and bounce to their hearts' content. The vast, taut, springy flooring doesn't end at the walls, but instead the trampolines continue upward to form perfect lift-off angles. Visitors can move along the bounceable terrain on the Main Court, throw themselves into foam blocks in the Foam Zone, or sharpen their competitive edges in trampoline-assisted sports such as dodgeball. Sky Fitness 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.
