Chapter 3. Basic Edges -
Classic Spirals in 4  Positions

When I use the word "spiral," a new skater immediately visualizes a position with the body bent way forward and the free leg very high in back. That is indeed a spiral position, but it is an arabesque spiral and not the classic variety that I want you to learn at this point in your skating education.

A spiral is neither more nor less than one of the basic four edges skated on either the left or the right foot, held in upright posture with good speed for at least a full circle, and prefer­ably longer. It is called a spiral because if you hold an edge without changing even a fraction the angle of the body lean, the radius of the curve you are making will gradually narrow, or spiral in, as your speed diminishes.

Note: This position in 2012 is referred to as a leg extension with the free leg held either in front or behind the tracing made by skating blade.
