Tumbling!!! Roll, cartwheel, round-off, walkover, back handspring, flip, twist, and more are all progressions of tumbling. MCG offers classes for beginner and intermediate tumblers who want to learn or improve their skills for fun or to incorporate in another sport like cheer or dance. We also offer Big Air tumbling for people who like trampoline-based moves that can even translate into moves on our Montana ski slopes! Tumbling classes are for kids in Second Grade and older.
