In my weight room there is one picture. It's 8"x10" stuck to backside of the door to enter the room. It's this picture and at the top where you see clouds and hillside, it reads "man the f#@k up". I look at that picture every time I'm doing my stretches. If I ever feel throughout the workout that I just can't do that set or last few reps, I'm already reminded that if those men went off onto that beach knowing what was very likely to happen under insurmountable odds but did it anyway, that there is zero reason for me not to man up and finish my sets.
