Faster to roll to one side, sit up by sliding legs under you and pop up. You don't need to kick to get the guy off of you before you get up. If you want to know how this shit fails, look at the Royce Gracie v Kazushi Sakuraba #2 fight. Royce was basically on his homosexual back and ass the whole time. He couldn't execute this stand up move because Sakuraba was going to soccer kick this kid's chest or face.
