What's a good routine that focuses on lower and outer chest? I'd like my lower chest to "pop out" a little more as the middle of my chest seems to be more round. I've recently started decline barbell presses but it's difficult since I'm not used to the angle. I've also concentrated more on cable crossovers and flies into my routine. Anything else you guys would suggest? What's worked well for you? I know my genetics may be against me so that's why I'd like to concentrate more on it to balance things out a little.

Thanks in advance.
