The thing I struggle the most with in my skiing is my upper-body at turn initiation (e.g., entry into the fall line).
My process for initiating a turn are:
1) Begin retracting outside (new inside) leg, begin pressuring inside (new outside) leg
2) Simultaneously with 1), gradually get my skis flat
3) Focus on getting "stacked" on my skis
4) Wait to enter fall-line and once I feel the centrifugal forces building, then I get onto my new edges (query: should I get on my new edges before the fall line?)
5) As I enter the fall-line and near the apex, increase pressure on my outside skis
Other than my question regarding timing of 4) above, I think generally this is the way modern ski technique teaches you on how to make a turn.
The more confusing thing for me is, what I should do with my upper-body. I do the whole "up/down" process (less if I'm truly carving at speed, more if I'm doing more pivot turns at slower speeds) to some extent in all of my turns.
When I do my "up" motion at step 1) above, I move "up" in the direction my skis are pointing. In other words, I try to keep my shoulders aligned with the tip of my skis. Then, in steps 3-5 above, I focus on rotating my shoulders and hips to keep them aligned with the changing direction of my skis. Then, once I am at the apex of the turn at the end of step 5), I do a bit of hip angulation so that I am properly countered.
This all makes sense to me from a biomechanical perspective. Skiing stacked, tipping movements followed by angulation (as opposed to "inclining" into a turn).
The following video however, is throwing everything I know about body position out the window:
At 0:20, the guy states, "my skis are still in the last turn, but my body is already moving down the hill in preparation for the next turn."
I interpret this to mean, when he is moving "up," he is actually doing it at an angle to the direction of the skis, and in a way, inclining into the turn. My questions are:
1) If this is true, doesn't this mean he is no longer "stacked" and therefore unable to pressure the outside leg sufficiently?
2) Won't this result in your upperbody being too much "into the hill"?
3) Shouldn't you be pressuring the new outside ski prior to tipping your skis onto their new edges? If your COM is already down the hill, I imagine that will put you onto your new edges without adequate pressure.
I'm confused, because he looks very well stacked over his skis and very well centered - but this emphasis of "throwing your upper-body down the hill" seems counterintuitive when trying to ski stacked.
