Good advice so far,...
-Pre-fatigue - always worth a try if you're a natural arm bencher
-Retracting Scapulae - also a gem if your front delts tend to dominate
-Training like a BBer - common sense that we all miss sometimes in our effort to chase numbers
-Non-Lock out - again, great advice if your arms tend to take over
a few other tidbits...
-Frequency - don't be afraid to hit a muscle group more than once a week. Too many people are so scared of 'overtraining' (horrible term, should be undereating and undersleeping!), that they shy away from doing work. I've done chest 2x every 6 days for a while now, and it definitely made a difference. Thibs has specialization programs where you hit it 3x a week!
-Skipping Flat Work - Flat bench has destroyed more shoulders than any other exercise. Many top BBers don't even do it, instead focusing on slight incline and/or slight decline work for the better overall stress of the muscles involved. I used to flat bench a ton (well, not really a ton, but you know), and my chest looked like crap. Haven't done flat in years, and even though I have now idea how much I could Bench (should someone ask on the street), I certainly LOOK like I could do a lot, and that's what I'm truly after.
THat's all I got for now... oh yeah, DAMN FRIDGE, you;re built like a... well, ... you know -lol
