I work at a university fitness center and run into this problem all the time. I call it “I can ride a bike, I can teach a group fitness cycling class” or “I can do a bicep curl, I can personal train anyone”. It is a fine line trying to encourage the students, but at the same time making them realize there is SO MUCH more to learn. How do you tame that cocky and arrogant attitude? The continuing education for these newbies just stops because they know it all. As an educator I am up for some ideas.
