This is from my chest training article.

Dips:I perform these the "Vince Gironda" way and it really hits the outer edge,giving you an awesome "V" look from the front.You want your elbows out to the side.Keeping them close to your body and going behind you is straightening your arms and that's how you do them for triceps.You want to imagine that you're doing a "Most Muscular"pose as you push yourself up.
The starting position is,with elbows out wide,place your chin on your chest and bring your feet out in front of you so that your body resembles a "half moon" from the side.Now lower slowly and under control into a "stretch" position.Now,pushing your hands together into a most muscular pose,rise .You obviously can't push your hands together,but try,and you'll rise....Girls stare at my chest a lot when they're talking to me,and I believe this move is the reason.
