I've tried them all. a close grip, about a palm away from shoulder width, is where I feel there is less of a sticking point than when I was doing it benching width grip. I'll have to stick with this grip for a couple more sessions to see if it makes a difference. I just don't understand it. my db shoulder pressing poundages are increasing each week like clockwork, but my bb shoulder pressing is going no where, and it's getting frustrating because at the moment I'm probably stronger db pressing than I am bb pressing. I'm thinking I was using too wide of a grip with the bb, so I'll try the norrow grip for a while.
