Tommi since you bring up the subject, are you trying to incorporate and layover different movements onto your present habits. Before you can change your old habits; you have to completely understand what those movements are and what they are doing to you.
Your present movements, or at least what I see from your posted video clips, begin with an outside leg extension, do you understand completely what this is and what it does? Do you see it when you watch your own video? An outside leg extension is not a release!!!.
It?s actually engaging the ski more. So it delays the transition of the body into the new turn. A leg extension raises the body, makes the leg long, and moves the Cg uphill. After the body is moved uphill toward the uphill ski, the uphill leg will become the stance leg, but this has done little to move the body into the new turn to create new angles.
Since the body has been moved uphill, it needs a new direction. The new direction comes from the uphill leg extension , which pushes the body into the new turn or toward the center of the new arc. This is what is happening presently in the turns you posted.
Tommi comment:How is it possible to pull the feet back and at the same time maintain flexing.
The reason I posted the above description of what you are doing, is because, you might be confused by your movements.
For example; we do not
maintain flexing in skiing. Flexing is a very short duration movement. It's a change in leg length, it's not supposed to be
maintained.
Flexing should be combined with tipping. Flexing first, to reduce the pressure on the stance ski, at the end of the arc, and then tipping occurs as the flexing leg bends and the hips move lower. Watch any of the WC video on the internet, this happens in every slalom turn.
Pulling back comes in as the skis are tipping toward the new edges. IF, (big IF), you get float because you developed or used energy from the previous turn, you don?t have to pull back during flexing and tipping. The float will hold you until the skis are engaged on the new edges.
If you did not get energy out of the last arc; you have to work harder with pull back because you?re flexing move can put you in the back seat and the skis will run forward.
Pullback should happen before the skis are pressured in the new arc. You can't pull back if you are extending. Extending is an essentric contraction of the quadriceps muscles and flexing is a concentric contraction of the hamstring muscles. So they can not happen at the same time. This means if you have started extending to get out of the turn (even a little) you can't possibly pull the feet back.
