Spend some time skiing with no poles. You hold a lot of tension in your arms and also assume an exaggerated position.
But then concentrate on the feet/legs.
No poles is not an excuse to be a full body rotator.
I was going to say the same thing but didn't want to point out what seems obvious to me. My wife has the same issue with a "frozen" upper body. Did you ever play basketball or football -- think of a good "defensive crouch" in which you have a strong core base but have your arms in constant (productive) motion.
