Sorry if this has been up before, but could somebody give some short tips on how to learn to shake one's shoulders. I don't have the coordination yet, so how do you practise that? The move should be simple ipso facto; right shoulder goes forward, right shoulder goes back, and then it goes forward again. But do this fast and in a shake-manner proves surprisingly difficult. I also heard the shoulder-shake shouldn't affect the movement of the hips (they should not shake). I karate the muscular motion starts with the hips, which is where my coordination skill is from.
