What about the grip width on the military press, I used to do it about 3 inches from each shoulder, but I felt my triceps being used alot and my delts less. How far should my grip be to really focus on the delts?
Hmmm Well for me the grip width is a bit limited due to biceps etc so for me about 3" past shoulder width is about as close as I can get unless my elbows are in front. Think of it this way you want your elbows at 90 degrees at the bottom of the lift, and when you figure this out you'll have the proper grip width on presses for you.
However for your tricep issue it sounds to me that you are doing the press using your triceps as they may be the stronger/more dominant muscle at this time, so I suggest that you not lockout your presses (one should also not allow the bar to be lowered bellow the nose/chin area) and work on keeping tension on the delts. By not locking out the triceps don't see as much involvement. Also make sure you concentrate on using your delts when pressing (you may need to lighten the load to accomplish this right now).
