In the past when I would train chest, I used to stick to lots of presses and then end the workout with some flyes. Sure I got stronger, but my pecs didn't grow accordingly. I hooked up with a new training partner about a year ago and he loves flyes. Which at first I didn't like the idea of that. My ego was to far ahead of me and I couldn't even think about putting flyes first or second in my chest routine. But eventually it sank in. And man what a difference it makes.
Normally I will start off with a pressing movement then go to a flye, then another press then a fly, pec deck, or crossovers. Sometimes, I will start on the pec deck and then go to db presses. This type of chest routine is hard to get used to at first, mostly ego, but if you can stick with it, it makes a world of difference. Least it did for me. My chest is now much fuller and my inner chest is actually up to par. That used to be a problem area for me in the past. I am not saying there is anything wrong with going from press to press, but adding some flyes in between doesn't hurt. Its just a good change up. This type of chest training works especially well for bodybuilders that have wide shoulder structures (clavicles) which me and my training partner both have and of course as you know, Jay as well.
One of my favorite routines that I do, and this hits the chest all over with a variety of equipment:
Incline db press
Incline flyes
Hammer strength wide chest
Cable crossovers supersetted w/
machine presses
or
Flat db presses
Flat flyes
Incline Hammer stength
Pec dec
Those are just two examples I do and I love the pump. Its great to go from pressing, to stretching to pressing to strecthing. Try it.
