Irina Slutskaya
The Biellmann spin was made popular by world champion Denise Biellmann. 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. The Biellmann spin, due to the flexibility required in executing it, is "a signature move for women in the sport". Male skaters, as a result, do not execute it as commonly as women, although a notable exception is Olympic champion Yuzuru Hanyu.
