Advice on tumbling classes: My 7 year old son wants to learn stuff like back flips, but he doesn't want to do dancing (so hip hop is out) and he doesn't want to do a traditional gymnastics class where you do the rings or the bars. He really just wants what I would call tumbling. Are there classes out there (maybe at dance studios?) that offer strictly tumbling type classes? I only know about that stuff in gymnastics and he really just wants to focus on floor stuff. Thanks for any help!
