The round-off is a gymnastic floor skill used to turn horizontal energy into vertical energy. It's technically very similar to the cartwheel, only that now you land on both feet at the same time. Another important technical difference between round-off and cartwheel is that when you do a cartwheel you spread your legs, while when you do a round-off, you should close your legs when your reach vertical level.
