Yes, the chest is one muscle, but you can shift the emphasis to a certain area. If I did nothing but inclines every day, my upper chest would be more pronounced than if I did declines all day. Makes sense? Arnold S. always said that when he shifted the focus on his upper pectorals, he was able after a while to balance a glass of water on his upper chest.
