I lead non-carvers of every age down the hill all the time making round turns that are fully completed. These skiers are not carving. Their skis' tails are not following their tips making pencil-thin tracks in the snow. All these skiers need to be able to do is turn left and right, and if we are on blue trails they need to be able to get their skis roughly parallel between turns. They get their speed control from line (size and completion of the turns). This is a major part of what I am teaching them.
@JESinstr, why are you saying carving skills are required for controlling a turn's shape?
I don't want to get into a right/wrong conversation. I am just going to state my views based on the functional design of today's equipment from which I form my teaching methodologies.
Place a moving shaped ski on edge, add pressure to the center of shape (under the arch), and it will begin to create circular travel. This is what I call carving. Carving is NOT about making pencil thin tracks in the snow. It is about one's INTENT to convert straight line travel into circular travel and competently manage that process and the resulting forces to a controlled endpoint. There are pure carves and there are "sloppy" carves and everything in between. So if we have different definitions of what carving is I apologize.
You are either carving or you are not.... I like this saying because in a sport that is full of grays, this is truly a binary thought from which one can develop a fundamental approach.
Skis either slide in a straight line or they create a circular path. In between there is skidding which is a no man's land. Tell me, if your intent is to create a "turn shape" and your are skidding, when are you skidding into a carving state (circular path) and when are out skidding out? Answer that and you will start to understand how important intent and supporting movement patterns are.
If I looked at you leading a group of skiers down a slope, I wouldn't be thinking carving. Instead, I would be assessing them on being center balanced and if rotary is being implemented around the arch vs through the heels. Centered balance and rotary around the arch are a prereq to properly building the edge angles that take you into the carving state. BTW, I don't intentionally teach rotary. Rotary will find its way into the mix. I just make sure that when they do employ rotary, they are doing it around the arch.
@James YES! When a beginner holds a medium wedge shape and is center balanced, the very fact that the wedge puts them on their edges (the big arch side of their foot) completes the requirements for the ski to carve albeit toward each other. Contrary to what others may think, the key focus skill becomes learning pressure management to maintain equal pressure (through the arch) on both skis in order to go forward. I spend a fair amount of time using drills to get the beginner to develop pressure management ESPECIALLY the release of pressure. From there it is the independent management of pressure to each ski that results in the ski turning the skier aka carving.
If you can accept my definition of carving, why wouldn't you want to have a beginner experience the carving capability of their skis right from the get go?
