could you explain how you use the concept of "apex" with beginner students?
Despite the confusion and display of differing understandings of the meaning of the term "APEX" (as it relates to a ski turn) that has been displayed in this thread, the concept is really quite simple.
The APEX is the single middle point of a turn. It's the point at which half of the total direction change of a turn has been completed. If a straight line was drawn from the point a turn starts, to the point that turn ends, the APEX would be the point along the turn furthest from the drawn line. Typically, in the type of turns most people make most of the time, the APEX is reached when the skis are pointing down the "FALLINE" (another term some probably believe too confusing for beginners).
There are a couple good reasons for new and lower skilled skiers who are trying to advance their skill base to learn the concept of APEX. Take a look around any public ski slope. 97 percent of skiers rush the top of their turns in an effort to get to and through the falline as quickly as possible. Their turn initiations are composed of a big rotary tail toss, in which the APEX (falline) is reached almost immediately, followed by a more drawn out speed checking bottom of the turn.
The first step for most of these skill deficient skiers, if they ever hope to move past this pesky technical plateau, is to gain an understanding of turn shape. By gaining an awareness of the top and bottom portions of a turn, separated by a point called an APEX, they can begin to focus on being more patient during the top portion of the turn, making the direction change that takes place there more progressive, and more symmetrical to that taking place in the bottom portion of the turn.
Lower skilled skiers I work with quickly come to understand this concept of turn shape via this methodology,,, they quickly clean up their turn shape,,, and they then readily recognize the tail tossing being executed by the majority of other skiers on the slope. They're even astounded and disgusted when they see it being done by instructors.
The other use of the concept is in executing basic drills. Many of the drills I use call for a variance of task to take place during the process of executing a single turn. The APEX serves as a useful point at which to make the change. These drills are low skill level orientated, and the new skier/learner needs to understand the concept of APEX to execute them properly. That understanding will continue to serve them later as the degree of difficulty in the drills introduced is amped up.
