|instructor comments was that I was over rotating the upper body and that I should keep my shoulder square to my skis. Another thing I've been working on is my pole plants. I don't thing I was reaching enough and sometimes I was skiing over my pole.
The over rotation comment is the same as what John and I were saying. My point is that this is hard to thing to change by just rotating your body less. If you get your hips involved instead of rotating, then it's easier to do. Note: some people get the same effect by focusing on moving their legs under the body (crossunder).
Try these static exercises at home:
1) From a standing "holding the cafeteria tray position" pretend a pole swing starting by leaning your head and shoulders forward as your arm comes up. Your butt should go back a little. Your pole swing should start with your thumb on top and your little pinky swinging up (top part of the hand comes back, while the ower part goes forward). Note how far out the hand goes and where the hand is laterally when you reach the point where your heel(s) come off the ground.
2) Try the same move, but open your wrist while swinging the pole so that your thumb and pinky stay level, but the knuckles move "out". Here your inside heel should scarily release. Note how far away from the skis the pole touch is.
3) Try the same move as two, but also rotate your shoulders to the inside. This fixes the inside scary release but flattens it out as well. The pole touch now appears useless. You feel the lack of reaching on this one.
4) From the tray position, move your pole swing elbow into contact with the side of the body and keep that contact through the entire swing. Start the pole swing by bending the inside knee only and moving the hip. Think of using the side of your body to push your elbow forward. Keep your head up. Use the thumb on top/pinky swing motion. The hand position should end on an arc in between where it did for exercises 1 and 3, but not as far away from the body. The outside foot should release before the inside heel comes up or you should have no feel for the inside foot releasing. It's critical that you do this move with minimal upper body motion. You should feel the shoulders stay square to the feet.
5) From the tray position with the elbows away from the body do the same move as 4. You should feel both feet release at the same time and you should feel a comfortable and powerful release. The pole touch will be no farther away from the body than exercises one and two, but will be farther away from the skis than #1.
#5 is where we're trying to get you.
