The Ina Bauer is performed by placing the feet in the fourth position in ballet. The front leg is bent forwards at the knee and the back leg is extended behind the skater. The front leg can be either on an inside edge or an outside edge. An outside edge Ina Bauer is harder to do. While the skater skates in a curve across the ice (necessary because of the skate positions), the back can be bent backwards. This is not mandatory, but it does add to the element.
