Question for instructors. Do you actually teach your students to bend the ski? ....
I can feel a diving board bend when I move along it.
I've been on skis that deliver that feeling.
I've been on more skis that don't.
If I increase the edge angle to tighten a turn, I
know how it works. That shortened radius happens because I've bent the ski more. That doesn't mean I
feel the diving board effect.
And my movements to bend the ski more were directed towards increasing the edge angle, not bending the ski. To increase that edge angle, I flexed the inside leg more, and/or pulled the inside foot back more, or rolled its knee down toward the snow more, and/or rolled my ankles more, and/or angulated more. Maybe other stuff too. I'm thinking in my head about my line and doing those
movements. I'm not thinking about the edge angle, nor the snow pushing back on my skis, and certainly not about how much the ski is bent.
In answer to the OP, I do not instruct my intermediate students, nor my beginners, nor the kids, to "bend the ski." I don't even ask them to think about "bending" it since they probably can't feel it. If I used those words, they would most likely take the direct approach and push on the outside ski. I see that pushing move in young racers all the time.
I do instruct my students to move body parts in specific ways.
