Absolute Air Park, Arlington

As owner Kam Bradley told Seattle's King 5 News, "There's not a lot of limitations." She's referring to Absolute Air Park's indoor trampoline playground, where jumpers spring from floor to wall, spinning and flipping until gravity yells "uncle." To keep the park free of limitations, she and her husband added activities for kids, teens, and adults such as high-flying dodge-ball leagues as well as bouncy fitness classes. Recognizing how the trampolines made exercising fun, they offer trampoline aerobics, which incinerates calories with a variety of aerobic and fitness activities, as well as boot camps that incorporate interval and circuit training during 55-minute sessions. While the fitness is a plus, they know fun is the park's main draw, so they enhanced jumping possibilities with snowboards and bounce boards made specifically for trampolines, as well as party packages replete with personalized birthday cakes and extra-large pizzas.
