Like im used to rotating my foot or "putting the cigarette out" in order to rotate my hips and thats my mental que, but if Im throwing a lead step in hook my foot is in mid air and I cant "put the cigarette out" so I cant rotate my hips so I cant throw the lead left hook!?

How do I do this?

Many thanks in advance guys as always!!!

(bare in mind I know this is dangerous and unadvised technique unless you are roy jones jr but I have a special situation it can be used)
