There is no cheating way to learn a round off. You should start by getting your basic shapes. First you will need good cartwheel that you can control most of the time. Start of by going into a cartwheel (don't go too fast) after you have started to turn put your legs together and snap your legs down on the ground. Make sure you keep them together. Once you get the hang of it add more speed. It may take awhile as it did with me but if you are determined you will get there. I am not very experienced because I learnt this a few months ago. Once you get it perfect it.

The Pinsleur Spanish method is an easy way to learn Spanish and help you speak it quickly in a way that is similar to how we naturally learn language. It's less of a way to teach you grammar and more of a way to teach you how to speak it.
