Not that a lot of programs aren’t guilty of this, but Cross Fit starts people off way to far ahead of the proper progression curve. I have watched their competitions on espn and some of the people competing don’t do squats and lunges, etc. correctly. No wonder so many of them have all kinds of k tape all over them. The only sound program starts people off with proper movement patterns and progresses from there. But I don’t know how many fitness instructors are doing that right now.
