"Anonymous. So are you saying we are unbalanced and would need something to hold which we don't have whist we are dancing. For heavens sake stop the smoke screen and say right out. Yes we are unbalance, because we have nothing to hold onto like we would have if we use a table to steady us as we try to simulate a move ultra slow. Have you heard of foot pressure."
Yes, your are unbalanced.
But you can dance through the positioin quite nicely - as you have pointed out, "foot pressure" - a drive from the standing foot, can convert a simple fall into precisely the kind of horizontal motion we need while lowering. With skill we execute a soft landing on the receiving foot, and continue the progress of the body gracefull through into the next step.
You can't avoid the imbalance without making your dancing discontinous - but you can certainly learn to make use of the imbalance to power you dancing. After all, you've been doing it over fairly straight legs in order to walk since age 2 - you just have to learn to do it in the knee bend case that is outside of non-dancer's experience.
