Just what the title asks. Should you bench press with your elbows at a 90 degree angle (as in 90 degrees from your body, not from going down on the press) and not hit your chest or have your elbows in a little and touch your chest?
The reason I ask is because I have always touched my chest and had my elbows slightly in but a trainer at the gym I go to told me to keep my elbows out and to not touch my chest.
