Arnold mentions in his book that he would keep his face still like thst to show how much control he had over his body. So while other guys make faces because posing is actually pretty difficult he would demonstrate superiority by keeping his face perfectly still. Its very very hard to pull off and one of the less talked about reasons he was so dominant. None of his competitors really even came close to challenging him.
Had to watch that twice Arnold was amazing! I find his physique more and more impressive as time goes by.
I didn't know that. Nice info.
