Ok so here is my problem. I have been making good gains in most areas (physcially and on the bar) but I can't seem to add to my chest. When I bench I feel my shoulders and triceps doing most of the work no matter what I do. I've experimented with grip changes, incline/ decline, and I've tried to pre-exhaust my shoulders and triceps before I bench as well.
No matter what I've done so far nothing has changed. I do flyes and cables but have had minimal success. I don't do steroids or take any kind of muscle building supplements. I've been lifting about a year now, I'm a 38 year old male, and everything else is progressing nicely. I don't know if I'm geniticly screwed or if it's something else.
Also, I've done 5x5, declining reps while adding weight, and a few other mass building programs for my chest. With all that being said, I know I'm way less experienced then a lot of people here so any advice would be great. Is there any other way to minimize shoulder and tricep involvement while pressing or a way to maximize chest involvement? Thanks in advance!
