Come burn some energy on our trampolines, tumble trak, balance beams, bars, ropes, obstacle courses, and foam-filled pits. Mercury also offers a special preschool area for toddlers up to age 5. Toddlers can swing on preschool-size bars, jump on a preschool-size mini trampoline, and tumble into a foam-filled pit. Mercury's AM Power Hours are one hour of action-packed running, jumping, and tumbling fun. AM Power Hours are supervised by our Mercury coaches.
