I think it is my shoulders since i'm feelin a lot of pressure there. I can "lock out" close to 300 so my triceps aren't the problem. My chest is weak but its only suffering because of an old shoulder injury. When i press anywhere over 200 the bar gets stuck about 3 inches off my chest and i can't push any further. Anyway, I'm going to start adding more overhead pressing. Behind the neck press Push Press and a assortment of raises. Does this sound reasonable?
