good male dancers

I just read an article "Sexist Dance Moves for Men". I was particularly interested in this article because of a new move i learned - the shoulders roll. It is as explicit as it sounds, you simply roll your shoulders alternatively. I had no problem with rolling my shoulders, but I had trouble trying to get it to look the way my instructor thought was right. "The rolling motion is driven by the Latissimus Dorsi and not the Delttoid nor Trapezius." (see below for reference). Well theoretically understand that to do, but it was literally a pain in the back trying to get only the right muscles to move. (you can go ahead and try..) Could moving a particular group be akin to "variable movement of the central body region"? 


"Good" dancers did wider and bigger movements of the head, neck and torso, and did faster bending and twisting movements of their right knee (greater movements of the right knee rather than the left were to be expected, as 80 percent of the dancers favored their right leg). In contrast, "bad" dancers tended to be stiff and plod -- and throwing their arms around was no substitute for fast, variable movement of the central body region." -- from the article

i'm finally getting the shoulder thingy right.
