Magazine after magazine and site after site I read articles about building the "perfect" "well rounded" chest. Hitting the upper, lower, outer, middle. Does it really matter what exercises your doing if your shoulder is making the same movement? Flys, dips, bench, push-ups. The same movement of the shoulders is happening so what exercise gives the ability to target one area better then another? What would make one exercise hit different parts of the chest when really the whole chest is working? It's impossible to activate one single area of the chest at a time. There's tests that can be performed to see how many muscle fibers are recruited in a exercise. I recall decline chest of any sort recruiting the most muscle activation in the chest but this does not necessarily mean your lower chest is going to be bigger then the rest of your pecs. This is primarily due to the range of motion. The truth is the more incline your chest press goes the more shoulders you activate. (increase in shoulder flexion) Eventually your to the point of a easier military press. Flys offer a great range of motion but how you respond to flys often depends on arm length. Long arms will make your bicep and shoulders take over most likely at some point. I personally like push-ups, dips, flat/decline presses, and pretty much don't believe in anything else. If your gonna train the chest get the arms out of it. Your objective is to build chest right? Now dips is obviously a arm workout as well but I like that one for overall upper body strength. How the chest develops will ultimately come down to genetics. So what do you guys think. Exercises targeting different areas of the chest, Are they bogus?
