What do you mean about 180 degrees turnouts?
I was confused by what you meant about 180 degrees turnouts. On many tutorial videos there are young girls doing perfect turnouts but there is nothing to suggest they have done it wrong and their teachers say they are doing it right? Should they be able to do it naturally or do you think they are forcing their knees? Also, in one video it said third position was unnecessary. is this true or was the demonstrator incorrect?
