I'm not a gymnast. I can't flip to save my life. Of course my complete lack of talent lets me know a few things about proper techniques,of which I have none.A backflip is something that most of you should never even attempt to try. Of course if you do it and don't have the proper training you're an idiot who's almost asking to mess up. Below are two videos of people flipping. One of them has success and the other person somehow avoids dying. Click,enjoy,be amazed and share.
