Beginner Power Tumbling is a 55-minute class in our Big Gym for girls 5 to 9 years old. Tumblers will learn skills like cartwheels, handstands and backbends. No pre-requisite necessary. This class is perfect for the gymnast who just wants to tumble–no bars, beams or vaulting in the class. Oklahoma Gold has the best facilities for teaching and mastering power tumbling in the state. We have five in-ground trampolines, a 70-foot in-ground Tumbltrak and a 100-foot in-ground rod floor. In-ground equipment is safer, helps tumblers with their confidence and leads to faster-paced skill development.
