Everytime I go to the gym, I have to laugh when I see Army guys in there. First of all they are not the smartest bunch in the world. But they crowd all the benches, don't re-rack the weights and do the most ridiculous exercises ever.
I saw a guy using the tricep pulldown bar behind his back. Some guys were holding plates and they were 'throwing' them in front of themselves. However one guy let go and it broke the mirror in the gym. Needless to say he got banned.
