Hum there's a lot of confusion about what ballroom (dancesport) is and how it compares to other social dances (including social ballroom). So dancesport is very unique as it was created for art and competitions. At almost every time, dance partners have to look beautiful. Whenever you take a shot, it has to be art. In addition, judges won't look at the whole dance; they will actually have flashes. Would you break the frame just one time and there is high possibility that the judge see the bad picture. And this is sport. It's absolutely not about you feeling comfortable with your partner while dancing. It's intended to the audience who look at you. You have to suffer to look good. It is very difficult to maintain the frame. So when you say that the kids are doing wrong because of their shoulders, you should look at AT dancers more carefully. In fact, all pure AT dancers, including teachers and performers, break the frame at a much much higher rate. May you take some shots and you would see how disgraceful they do with their shoulders and the alignment of their body. You have to see the dance in action to not see the imperfections. With the exception of cortés, colgadas and some advanced figures, you won't see much pictures of AT. Wonder why? Because they just don't look good with basic figures. On the opposite side, you will see lots and lots of ballroom pictures. And to answer to those who say that the kids are cheating with their choregraphy, I would tell them that I dance like them in social events. It's very possible to look good when not performing a predetermined choregraphy, may you care about the posture and the frame. Guess about what people are talking at the bar? About the guy who have strong posture.
