When strangers look at each other at the gym and attempt to remain expressionless because they are either checking the other person out or don't want to invite conversation. The former usually applies to men while the latter usually applies to women.

When you’re at the gym and a douche bag approaches you wanting tips on his form. You just hit him with the resting gym face and crush his soul.
That loser Jared tried to talk to me at the gym again....but I hit him with the resting gym face and he retreated immediately.
