Some of us here do effectively have trained eyes, not professionally maybe,It's actually pretty hard for the untrained eye to determine whether someone's bad posture is the result of skeletal formation or bad habits. Anatomy books love to give a picture of how the femur is set in the hip socket, but dig a little deeper and you find that not only can it be sitting quite differently from person to another, but that the angle of the femoral neck can be quite drastically different as well.
but based on our own experiences of working on our own bodies and dance.
One clue is to look how and where partners connect and separately
how they stand and walk when apart. It's often quite visible.
Clearly you know your own body but surely the point is that we should dance
what we are and not adopt some artificial bearing because teacher says or the
unnatural connection demands. From my own experience I would maintain
that most of us can change our posture for the better outside the dance;
that improvement should be maintained as our normality in life and thus
brought to the dance. Because of my own personal physical situation,
a back injury and a later unrelated operation, I have corrected my bad posture
resulting from unconscious pain minimising and strengthened my body
more than once. Once started you have to continue.
But you are talking about a minority and we should not be generalisingAnyway, my point is that it's easy to judge other people's bodies and use of them because we aren't IN them. We don't know about their skeletons, their injuries, their ligaments and tendons. We barely know about our own. Do we as a culture spend too much time sitting and not enough time strengthening? Oh yeah! Is a weak core always the answer to what you might perceive as "bad posture"? No.
based on a minority. But we surely can generalise about the damaging influences
impact of sedentary lifestyles on average bodies which also affects those
with physical differences, be they large or small.
Without further analysing I will make the observation that Tango is the only
dance I know of with such exaggerated posterior emphasising postures and
some of that is rather more than just fashion but directly attributable
to teaching style and/or unfit non-dancing bodies.
