I don't get people who arch their back on bench to lift "more" weight. I know that's what power lifters do and all, but it's cheating IMO, reduces the total distance the weight has to travel. Let's see you lift the same weight with your back flat, then tell me your bench 1RM is 1000lbs. Nobody counts half a rep with a flat back, why should arched back get that benefit? It's like crossfitters who can do 75 kip ups but only 10 pull ups. Can someone explain?
