Why are you turning the squat rack around?

Little questions like this tend to pop up in health clubs when I train as I travel. The rack was of course set up so that the person squatting would be able to look in the mirror as they curled - I mean squat. So I understood the nature of the question and after explaining that it was difficult enough the stare at my face long enough to shave mush less when straining during squatting I gave her the real reasons.

#1 - Always relying upon a mirror can ruin your own kinestetic (sp?) sense of where you are in space when you don't have the mirrors feedback. Most people cannot "feel" where there arm is positioned or much less where a foot is turned or hand is turned unless they have the visual input from the mirror. A bad habit when they have yet to mirror the world so you can check your form every step of every day.
A mirror can be helpful for a spot check - but once you see what you want to check - get away from the mirror and re-create it by feel.

#2 - Since my goal is to compete in powerlifting it is important to train the way I will compete. There are no mirrors at the meets - only judges. I want to know my depth and feel of my squat perfectly without visual feedback.

I thnk she actually believed the initial reason of not being able to stand more "face" time in the mirror (this is a joke BTW). But seemed to accept the other reasons as well.

So - are you relying on the mirror? Or can you feel where you are in space?
