Here are his tips for executing the perfect turn:
* Aim your chest directly downhill, regardless of the angle of your skis.
* Lean forward, not back. Hold your hands out in front of you, as if gripping a bicycle handlebar. Feel your ankle and foot press against the tongue of your boot, not against the heel.
* Unweight--but don't lift--the inside foot (the left foot if you're turning left, the right if you're turning right). Straighten the outside leg to about 15 degrees and drive it down into the snow, as if you are cornering on a bicycle.
* Constantly use your poles for pivoting and rhythm. Plant a pole to the inside of the foot in the direction you're turning and pull your body toward it.
