CONCEPT
Compás
The compás is the biomechanical reference for the opening between the legs: the distance and angle at which the feet are placed on the floor to define the base of the stance. In the eagle gesture, the open compás sets the width from which the femur can rotate externally without the pelvis losing its neutrality. It is not a fixed position; it is the geometric variable the body modulates based on how much rotation is available at hip and ankle.
Why it matters
External rotation requires joint space, and the compás is what creates that space. When the opening between the legs is too narrow, the head of the femur finds no room and the rotation spills over to the knee or the foot. When it is too wide, the pelvis is dragged into anterior tilt and the torso compensates forward. Finding the correct compás for one's own body is a prerequisite for the eagle stance to be held by biomechanics rather than by effort.
How to feel it
The body perceives the correct compás as a wide but stable base, with the heels firm on the floor and no sense of pull on the inner thighs. The adductors are active but not shortened, the knees align above the feet and the pelvis is felt as suspended between the legs, not falling forward. When the compás is opened in Routine 1, the skater notices how external rotation gains range without changing the pelvic placement.
Common mistakes
- Opening the compás by forcing the aperture and letting the pelvis fall into anterior tilt.
- Closing the compás to feel more control and sacrificing the range of external rotation.
- Seeking the opening only with the feet, without accompanying the movement from the hip.
- Keeping the knees turned inward as the compás widens, losing knee-foot alignment.
