YOUR body should dictate the range of motion for any lift. Arbitrarily picking a set ROM for any lift may put you in a position where injury is not a matter of if, but when. Full ROM bench presses just don't work for some people because of their body proportions/muscle insertion points/flexibility. All you young guys take heed. Whether you believe it or not someday you will be old, and I can tell you from experience, and the experience of working with a large cross section of trainees that the most important thing you can do in regards to training is not get injured. No one ever thinks it will happen to them until it does. Whack your shoulders or lower back and you will soon find how little can be done. You can't train if you are injured and MOST long-term trainees eventually end up injured. The sad part is, almost all of the injuries that occur could have been prevented had the knowledge been there, and the ego been absent.
