it's all relative. people lift weights to help develop more functional strength and to look better. When are you ever going to need to benchpress more than your bodyweight out in the world though? You will never be in that position at any job where you will be laying down and pressing something up. Sure you will use many pulling and squatting and curling movements, but chest presses? Manual labor is for suckers anyways.
Wrestling is technique, position, and leverage and has very little to do with actual strength.
