Watched the demo at 4:23 again. She is doing a rotary push off of the downhill ski pretty much every time. That means she is bracing against the downhill ski and up extended off of it to push herself up the hill and creating whole body rotary, which also rotates the ski a bit along with it, basically stemming it or at least the tail flairs out from that whole body rotary from the push off. In that demo she is attempting to do some kind of javelin thing.
I'm not really sure the point of the video, it would help to see a translation of what she's saying. There is a lot of stuff I don't like about the demo. I don't like the push off of the downhill ski. I don't like the whole body rotary. I don't like the overly cranky knee. I don't like the up move there, which is opposite of what she does when she skis full out in the bumps; I don't like the tail push due to the push off of of the other ski...its a classic up stem...just refined by an expert. I also don't like how she is preventing mobility in her hip socket for the remainder of the turn and losing upper/lower separation. I don't like how aft she is trying to smear out the turn.
There is probably something focused she was trying to demonstrate or accomplish with that, but without knowing what that is, there is an awful lot to NOT like about that demo.
I do like that she's not twisting her femurs to do anything.
Its late...I will watch the rest of the video later...its a long one...I have a busy day tomorrow also..
I hear that you do not like the steps in her progression. Do you like the result? She skied in the Olympics five times for Japan. She won the 2007-2008 World Cup in Moguls. The video mixes very clearly shot videos of steps in a progression that is well thought-out. Mixed in with these steps are promotional clips of her skiing and some sit-down talks with the camera. I've watched it all the way through; it's long, granted. So if you are skipping around, you won't get the way she alternates between those three things. This format is different from most ski videos.
I like how she skis. I like how she shows the steps in her progression; this is good teaching. I turn off the audio; it's not really needed. You are right; she is using rotary push-off in the part you have watched. If you stick with it, there are parts where she uses muscularly rotated femurs to turn the skis. I was surprised as some of the things she does, too, for the same reason as you. But if her steps along the progression don't match something normally promoted (by PSIA, etc), I don't care. It's a learning progression. Proof is in the pudding.
