Trademarc I am interested in knowing what you're doing when you say military press... Db's or BB? Smith machine? You're standing? Do you boost them up yourself? Technique etc..
My understanding of the two is shoulder press is generally done using DB's whilst sitting, and military press is done with a BB (seated or standing, although steated allows for a heavier and more controlled load). Shoulder press works stabilizer muscles also, and also allowing a greater range of motion and you don't have to worry about hitting your head. I pressed 36's for 7 on Friday. Whereas military press allowed for a greater overall load to be pressed.
