Its funny that some people here are amazed that not everyone looks in the mirror. At my gym (primarily a weightlifting gym, but also home to powerlifters and strength atheletes) pretty much the only point of using a mirror is to check on lifting technique, not to check out pecs, side trips, abs, etc etc.
We call the bodybuilders at our gym "mirror-boys" due to their constant checking of their bodies in the mirror. I feel like telling those guys sometimes who check out the mirror after each set, that they look just like they did after their previous set!. For me personally, I can appreciate bodybuilding as a sport also, so I an fine with it, but some of the lifters think its a bit gay, so my advice is for bodybuilders training in that kind of environment to keep the posing low-key.
