tuck em in a bit. it takes the stress off your shoulders. "pec" benchers don't tend to have much longevity due to tears and RC injury (in general). with tucking your elbows, you'll also notice youre not so "stretched" out at the bottom. you could bring an empty bar down and probably go a few inches further...thats what you want. It puts you right in the middle of your range of motion where most people are the strongest. you don't want to start your push at your absolute stretch limit.
Well thanks for the help everyone, I have been training with "elbows in" for a few weeks now and i beleive I will definatly stick with it, although it hurts my shoulders more I am definalty stronger with the elbows in....
