I would just like to say that there lots and lots of people who say that incline can make your "upper chest" larger simply because someone else told them and they copycat the samething. These people can not come up with legitimate proof or evidence other than the fact that they know a few guys who have huge "upper chests" with nice vascularity (and they do inclines). I believe that incline simply takes a large part of the load off the pecs (yes, all of it) and drops in on the shoulders. When was the last time you saw someone change the shape of their muscle from doing certain exercises. I noticed the upper region of my chest got bigger when my whole chest got bigger. I also noticed I'm plenty sore in the same region from doing flat stuff. Be a free thinker and research for yourself.
