IMO benching isn't the best chest builder, however it is the best upper body exercise. Guys that can bench heavy have a fuller looking upper body. Can you build big legs without squats? Ya but they don't look the same as a guy who does them.
You know how some guys have huge chests, shoulders, and triceps but something just doesn't look right? they just dont flow together? I wonder if that has something to do with the fact that they may not do exercises that uses several bodyparts.
Why argue that benching works as much of your chest as it does shoulders and triceps, isnt that a good thing?
Did Ronnies squatting,deadlifting,and benching kind of tie his whole body together?
