if your doing the Bodybuilders style bench press (wide grip elbows flared out and bringing the bar close to your collar bone) Your asking for shoulder injuries, do yourself a favour and pull your shoulder blades back and down to create an arch, cheep your chest prowed. Flex your lats and core keep your butt on the bench, keep your elb...ows in close to your body instead of flared, allow your grip to be closer to enable this, grip the bar tight. Bring your feet back AND wide as far as you can while still maintaining contact on the ground with your heels. When you unrack the bar being it to your nipple line and without bounching the bar touch your chest and as you push the bar up drive your heels into the ground as if doing a push press. This is the correct technique for the bench press.
