The Biellmann spin is a spin in figure skating. It is performed on one foot. The free leg (the leg not on the ice) is pulled up from behind and pulled above the head. The knee is bent slightly and the back is bent backwards into the spin. This forms a teardrop position with the body. In the classic version of the spin, both arms are used to hold up the leg. A slightly changed version has one hand on the skate and the other hand on the arm holding up the skate. A change can be made in that one hand can be dropped. If the hand holding up the spin is on the same side of the body as the leg, the spin is referred to as a "one-hand Biellmann spin", because the spin is being performed with one hand. If the hand holding up the spin is on the opposite side of the body as the leg, the spin is referred to as a "cross-grab Biellmann spin", because that hand has to "cross" the body to "grab" the skate.
