Spins are an element in figure skating where the skater rotates, centered on a single point on the ice, while holding one or more body positions. The skater rotates on the part of the blade just behind the toe pick, with the weight on the ball of the foot. There are many types of spins, identified by the position of the arms, legs, and torso, the foot on which the spin is performed, and the entrance to the spin. A combination spin is a spin with a change of position or foot. Spins are a required element in most figure skating competitions.
