Watched a couple of videos on youtube of jay cutler, he seems to bring the bar to his chest, although he does have the bench on a slight incline. I have always been tought to shoulder press until your arms reach 90 degrees, any lower and you risk injury. My front delt exercises are freeweight press which i do at a slight incline and bring them to 90 degrees. When smith pressing i have the bench upright about 4 inches back from the bar, i bring the bar down to where my arms reach 90 degrees and that is just touching my head. How do you guys do it, whats better? Input appreciated
