CORRECT:

[ A ] A strong core is the keystone of powerful turns. Keep your abs engaged and your shoulders level and aimed at your next turn.

[ B ] Turn your legs against the stability of your solid upper body. Imagine twisting your femurs in your hip sockets to direct your skis across the hill.

[ C ] By winding and unwinding your body throughout the turn, you build up and then release energy that helps you spring from turn to turn.

INCORRECT:

 [ A ] When your upper body rotates across the fall line as much as or more than your legs and skis, you can’t gain any leverage over your edges.

[ B ] If your inside hand gets uphill of your inside knee at any point in the turn, your shoulders have probably turned too far across the fall line.

[ C ] Over-rotating your shoulders puts your weight over your inside ski, which can cause your skis’ tips to diverge and your tails to cross.
