The infamous "fourth point" ... using legs and hips to initiate the recovery phase of the double pole motion ...
... shoulders rolled forward and elbows forward as you are about to drop your center of gravity ...
... creating a very powerful force to overcome inertia when the poles contact the snow
... arms and hands follow through like the end of a whip ... while the hips and legs are already initiating the recovery phase ...
... and me attempting to do the same thing!
