Thanks for explaining. Double checking the PSIA alpine technical manual, I find that in Chapter 2 it first defines the skills concept, then proceeds to discuss explicit movements for the four skills. I believe that I may have misread your post as stating that PSIA only teaches skills and the movements happen intuitively. Although I believe that many PSIA trained instructors teach for some movements to happen intuitively, there are plenty of examples of teaching specific movements as part of the ATS. For example, using the "guided discovery" method of teaching, we often give the student a task to do without telling them how to do it. Their challenge is to discover the movements with only the goal of the task as their guide
(although the previous work in the lesson has often laid the preparation for accomplishing the movement). Yet there are also many times in a lesson when a pro will direct their student to "stand taller", "widen their stance", "bend their knees" or even "tip the boots". Yes the movements are intended to develop skills, but we still teach movements.
A few months ago, someone posted a video of HH himself in a clinic. It was 12 minutes long, and HH talked the whole time! They never moved an inch. The best part was, whoever posted it thought it was an example of a great clinic. That was all I needed to know about PMTS.
