Compared to my shoulders and arms (and even my abs), my chest is virtually non-existent. For as long as I can remember I've always had pretty muscular arms & shoulders (most likely down to drumming, as I didn't really start working out properly until a couple of years ago), but where you tend to see pictures of fit guys, they look like they've got a couple of thick-cut steaks for chest muscles, whereas I appear to have a pair of medium-sized pancakes.
I've read a lot of information suggesting that push-ups, particularly wide-grip and incline, help develop the chest; however I've also read (and I currently can't find the link) that this will only develop the lower chest, and for real mass I should work the upper chest with flat barbell presses, incline presses and flyes, with 4-6 reps at 80-85% of my 1-rep maximum.
However, I also have a custom pull-up routine that includes close & wide grip (straight legs and legs out), overhand, bar checks, etc. and that feels like it works my chest more than anything else, despite the fact that I originally found it looking for core-strengthening workouts.
Consequently, I'm at a bit of a loss as to where to start; considering my shoulders, arms, abs and even my back all seem far more developed than my chest, I'm not sure what I should be doing or how often I should be doing it.
Overall, this is the kind of physique I'm after:
Although his chest isn't huge, you can definitely see lines that define his pectorals. That's what I want.
