I read somewhere that going wide (not excessively but a normal wide grip) makes you use delts a lot in the press and that a closer grip would enable you to use more pecs (as the delts wouldn't be in a strong position). Any truth to this? How close should it be? I'm not looking for powerlifting advice, just want to emphasize the pecs for BB'ing. I know that you should squeeze the shoulder blades together throughout the whole set, maintain a slight arch etc. Just wondering about the grip.
