WTF? that doesn't show any muscle named Upper Pectoral, or inner upper pectoral? Is your IQ below 70? lol.... I don't know how to get into your wittle head that it's just one big ol muscle. If it's small on one part it small on another. The anatomy chart you posted if you'll take the time to actually look at it shows what I've been telling you all along.
NOW, AGAIN... It's called the pectoralis Major.. There is no Upper Pectoral or lower pectoral or an inner pectoral. THAT is my point. Your post doesn't do anything but show how you are trying to argue for the sake of arguing. You pull stuff out of your ass all the time. Stuff that is wrong. I grow tired of seeing all the misinformation you are posting..but I digress..
(to note there is a pectoralis minor but it is a very small triangular shaped muscle near the thorax.)
Now, I also want to address your other little comment .....EMG studies..wait, I obviously have to explain what that is. It stands for electro myofibril graph. This is a machine that's used to gauge how much work a muscle is performing. This machine has shown in multiple studies that the exercise that gets the most activity from the pectoal is Low grade decline Dumbbell presses. 2nd is traditional bench press. My point.. There is clinical data to support what I'm saying. You can choose to believe it or not. It doesn't change it from being the truth.
