Biellmann

The Biellmann spin is another variant of the upright position.  Introduced by Denise Biellmann, this spin requires great flexibility.  Starting in an upright spin position, the skater reaches back over her shoulders and grabs the blade of the free foot's skate, which is extended "up" towards the ceiling (the back and body of the skater remain upright too).  Its kind of like doing a "splits" in a vertical position.  This can be very impressive if the skater can get into position quickly and hold it a long time.  It can also be very awful if the skater wastes three or four revolutions getting into the position, and only holds it for one or two once she gets there.

The Biellmann spin that Selena performs here is actually the second part of a combination spin - she demonstrates a very nice quick transition from the camel position to the Biellmann position.

The spin that Selena is performing here probably has a real name, but I don't know what it is.  Since I don't know its name, and she does it better than anyone else I've ever seen, I'll call it Selena's Stretch Spin until someone tells me otherwise...

For obvious reasons, it is only performed by very flexible skaters..  

This spin requires a stretch similar to the Biellmann, except that the freeleg is elevated in the forward position.  Generally skaters grab their blade or the back of their knee to help maintain this very impressive position.

Note that in the pictured spin, Selena is skating on her right foot, making this a back spin.
