Lena has some super structured system, explaining which one can see clearly the principles of dance. And she also has a gift to explain in a manner when it gets clear. It is funny to watch yourself, when after long dancing you suddenly understand what Lena wanted to say at the lesson.
Sometimes tango is taught as some set of movements ,but Lena has an integrated concept about how body moves and why. And when you use it all in your dance, all movements come as consequence. Not because you have to do them, but because cooperation with partner is built in a certain way, because it is easier to stand that way.
