Biellmann spin

It is executed by the skater grabbing their free blade and pulling the heel of their boot behind and above the level of the head so that their legs are in an approximate full split, with the head and back arched upward.

[2] The Biellmann increases the complexity of a skater's short or free program only if they execute eight revolutions, in either a backward and/or sideway position without any changes, before attempting the Biellmann and if they clearly increase the speed of the spin.

Advanced novice skaters must complete six revolutions before executing a Biellmann spin.

[3] Like other categories of difficult spin variations, the Biellmann is counted in a skater's score, in both the short and free skating programs, only the first time it is completed.

[5] Russian figure skater Irina Slutskaya invented and was noted for the double Biellmann spin with a foot change, which is executed by the skater reaching back with their hands, grabbing the blade of one skate and pulling it straight over their head, and then performing the same action with the other skate.
