Facial expressions say a lot. As in when you smile everyone assumes you're happy ect. When lifting weights, you are essentially causing your body to hurt. The facial expression is a sign of distress. and is natural.
I've always asked to myself..why do we have to put those funny faces when we lift heavy weights in the gym..It's sometimes like we're pooping or having a heart attack-faces like hehe
