Quoting from the article:
In Diagram 6, the arrows signify roughly where the pressure will be at its greatest. This means that I need to be in a strongly inclined position (with appropriate angulation) at these points and what happens in between is not so important as the pressure I am dealing with is negligible or aligned with the direction my CoM is travelling.
So why do we need to ski the entire turn perfectly stacked?
Looping back up in the article:
The position in “Diagram 3” is very common among high level skiers and particularly candidates around level 3/4. This “over-angulation” is just as unbalanced and possibly more dangerous than if the skier were to incline or completely bank into the turn as in the first diagram. The ski is over edged and the centripetal force has to go somewhere as it is not opposed or balanced. This usually results in over straining of the leg muscles to deal with the pressure and failing that, the skis jetting out in front of the skier. Over angulation often feels like there is too much pressure or increased “g-force” through the turn. It can feel like leg muscles are struggling and your whole body is getting smaller. This struggle is not only uncomfortable, it also prevents the skier from moving further inside further and increase in edge angle and centripetal pressure. At slow speeds this position can be dealt with through muscular effort. The interesting thing is that most people would say that this is a good position.
And further down....
....being inclined enough.... The turning becomes extremely smooth. One can build more pressure due to the extreme edge angle of the outside ski and there is no struggle to be felt. That feeling of “g-force”, pressure, strength and struggle as felt in the over-angulated position was not there. It feels simple and easy because the forces are aligned and the skeletal system is doing its job.
Working on toppling this past Australian season I experienced this relaxed, no struggle carving whilst making probably the best angles ever. Huge reduction in effort. Recommend trying it out.
