Fascinating. Natalia Makarova practices in center floor. The video quality is very poor, but we can still see her extraordinary control and balance. Notice how she always "gets on her leg"—she places it accurately and it is absolutely perpendicular to the floor—and therefore the free leg and her torso and arms simply float into position. She knew she had to place her toe and drive down. And notice when she does the pirouette en attitude en dedans how she throws the leading arm and simply "coasts" the turn. It's mesmerizing.
