Rather than trying to judge angles and lengths in photos, let’s look at the issue conceptually. It’s really simple geometry. Sorry for the quality of the drawing, but I think it will work to make my point.
Let’s start with position 1 with a certain amount of flex in leg A and B.
If one leaves foot A in the same position and foot B tips. The center of mass will want to move to position 2. If foot A stays in the same position on the ground, Leg A must get longer. Even if leg B stays at the same flex it will move up leg A.
If the tipping is accompanied by increased flexion in leg B the center of mass moves faster and father, the leg lengthens faster and more, and leg B increases vertical separation even more.
Will pressure increase on the stance leg? Absolutely? Was it because the skier PUSHED on leg A, extending it and moving the center of mass? NO.
Pressure increased because tipping decreased the radius of the turn. Luckily because leg A is straighter, more of the pressure can be taken by the skeletal system and not the muscles.
An important point for some people is the following. If leg A is held back from lengthening during tipping, the center of mass will not move as effectively and most of the force will have to be taken by the muscles.
I often hear people talking about pushing the legs out to the side to create angles. As you can now see, tis is a misinterpretation of what is going on. Create angles by tipping and free leg flexing to bring the CM inside.
With active tipping (and free leg flexing), the body wants to move into the turn. 1) There will not be any need to push it there or push the stance leg out and away. 2) Also, don’t actively hold it back by holding the stance leg flexed. Relax and allow the leg to lengthen out.
Hope this helps.
