Sometime the "cross legs" should be replaced by a hop with quick spin. The more that you have trained, the less time that you will stay in "cross legs".

That's why the jumping kick is better. Not only 1 is better than 1,2, if you cross your legs when your body is in the air, you will have less risk.
