I think Sasha is in a spiral in that "I" shot and and spinning for the "Y" shot.
I think what was so impressive wth Shiz in 2006 was the strength combined with balance and she still stayed on a great edge! Plus, it was a creative departure from the cookie cutter spirals we now see.
Here's a few more Y-spirals:
More Miria impressive flexible moves:
No one yet has done a Charlotte Spin.
Good line is of the essence for a dancer on or off skates
btw, has anyone thought of the flexibility one needs to do a proper sitsspin?
What's so shocking about that is I never really liked Sasha's or Caroline's sit spins, yet I think Michelle has the nicest back position in her sit. Goes to show it's not really ALL about the most contortionist flexible in every position, but how the actual position is stretched and detailed. So, yes, Joe, I agree with what you and Passion have said:
Sit spins require quad and hamstring strength, but no real flexibility.
I think what some fans are talking about is what they perceive as being ballet. Ballerinas, as you know, raise their legs in arabasques (spirals) at any height and they do it without the assistance of an arm or hand. It's pure muscle. Contortunists must use the assistance of hand/arm to get into unnatural positions.
When the hand/arm is used in I spins, it is no longer ballet-like. But it can be and it is a big trick in acrobatic dancing and figure skating. Awesome? That's up to the viewer.
