I have been debating whether or not to keep some sort of overhead press in my routine. I know that they are great for triceps size, and or course front delts, but is there really a significant contribution from the side delts. I was reading some stuff on other sites and I came across a few things. First of all, I have read that the medial delts are worked the most during the mid to top portion of the press, from about the top of the head up. Also, they are apparently worked more when the upper body is straight up and down, not tilted back. This makes sense. One site talked about doing presses in the top 2/3 of the movement, using any number of variations such as db's, front presses, or behind the neck (maybe arnold presses would be good too). Has anyone ever seen emg studies on this, or anything else that would suggest it is true. This would be fine with me if it worked because it would also be the portion of the movement that most heavily works the triceps. I really don't need my front delts to be bigger, as they are already disproportionate to the rest of my shoulders, as is the case with just about everyone that I've seen. So I guess the questions are these. How good are overhead presses for medial delts, and is the top 2/3 portion of the lift what I should focus on? As of now, I have basically dropped them out of my routine and made heavy upright rows my main shoulder movement, with one arm side laterals my other light movement for side delts (on another day). I can't be sure, but I think my triceps may have shrunk despite a lot of chest pressing, and always including some sort of close grip press.
