Hustle is a three count dance. Like west coast swing, it is danced in a track. Keeping the track is difficult, so yours may rotate a bit when dancing to faster music. If you haven't already learned it some other way, pick one of the count methods illustrated on the figures and stick with it. The simplest moves are three count.
More complicated moves are usually multiples of three counts.
The step illustrated here is a simple pass, where the man and woman trade places. The woman turns sideways to face the man as they pass. The man can do the same. Some men prefer to keep their shoulders facing forward as long as possible before turning to face the woman.
