One of the most famous images of Arnold from the 1970s is of him performing a side chest pose, looking with an uncharacteristically serious, scrutinizing glare at the camera—or at least it seems like he's looking at the camera. Training partner Ed Corney recalled the real origin of the image in an interview with Bodybuilding.com:
"When Arnold was doing his side chest, they shot that by cutting a hole in the mirror he was looking at and putting a camera behind that hole. So they got him right on." Corney said. "Arnold would be looking at the mirror as a guide doing his side chest pose and they captured that."
The bodybuilder gazing at himself in the mirror is a stereotype that other gym-goers love to deride, but Arnold knew the true value of this technique more than anyone. Look again at that image; he isn't gazing at himself out of vanity.
"For a guy like Arnold, a mirror is a tool for self-criticism," writes Joe Weider in his autobiography "Brothers of Iron." "Looking at himself, a serious bodybuilder isn't admiring. He's looking for trouble. And he sees trouble, every time."
