When dancing with a woman, you need to realize that you have your own engine of movement and she has hers. You move your weight and she moves hers. You don’t move her. You indicate which direction she needs to move herself by operating your own engine. However, in order to be able to do that, you need to understand how her engine is supposed to work. In other words, you need to know how a perfect engine should operate in terms of transfer of weight and coordination. Where is she on the foot exactly and how is her body counteracting various body parts? (I didn’t say which foot she is on. You should already know that). Then, you have to realize that unless you are dancing with a world champion, your partner will have a faulty engine. Some will have better engines than others and women with different engines have to be lead differently. It all depends on the quality of their movement and weight transfer. If you understand that, then only then, you will be able to lead properly.
