Compared to some guys around here, I know sweet fuck all about working out, but even I can see that a bench press is not a "lever arm" movement. The weight is directly over its support throughout the lift, whereas a movement like a goodmorning uses the back as a lever and carries a greater risk of injury for a careless or inexperienced lifter. For a veteran, maybe not so much.
It's always fun to watch someone bash Moose, but you'd better chill cross. You're all bent out of shape. We're not curing cancer here.
