Boys Power Tumbling is a 55-minute class in our Big Gym for boys 7 to 18 years old. 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. For the boys advanced level, high-level trampoline skills are needed (flipping), however, intermediate level tumbling level skills will be taught (cartwheels, round-offs and handsprings).
