Points for Double Poling (Classic/Skating Technique)
Extend the arms forward, extend the body forward by flexing the ankle joints, and then fall forward onto the poles.
Bend the upper body forcefully at the waist to load the poles; then drive the arms down and back. Let the upper body sink to between 60 and 90 degrees from the vertical.
Bend the legs just enough for comfort.
Follow through with the arms until the ski pole forms a straight line with the shoulder.
Make sure that the shoulders lead the arms when returning to the starting position.
The upper body rises visibly before the arms begin reaching forward.
Make sure that the arms recover in a circular motion.
Use more pronounced front-and-back motion from the ankle as skill improves.
