As I entered the end of my second wave of 5/3/1 I was noticing a lot of development in my traps, shoulders and chest but my neck was awkwardly thin so I started working it out a few times a week and noticed it was pretty weak. I was wondering what benefits are there from having a strong neck besides being well proportionate? I just thought of something else to ask. My chest and shoulders and getting bigger but my upper chest is still kinda flat. I do bench, incline db press, and db rows on my bench day is there something I can add that will really hit this area and help bring some size to it?
