Just one quick pointer -- pin your shoulders back and down, keep a tight arch, tight stomach (take a deep breath) and keep the upper/mid back locked tight . . . this really helps me from being a "pure shoulder" bencher. I benched a long time just using delts, pretty much b/c I kept my elbows flared out and my back wasn't tight at all . . . since making an effort to try more of a "powerlifting" style, I'm getting stronger and my chest is getting more activation during bench. Shoulders still obviusly get hammered, but I was doing almost a pure shoulder bench. And my chest reflects that. LoL
