Bench Press, for those beautiful chesticles that will bring all the boys/girls to the yard.

If you're looking for aesthetics, then 3x5 isn't the best rep scheme. On the other hand, it's probably a good place to start and work up to more weight so that if you make the switch to bodybuilding for the upper body, you'll be able to move more weight. Plus, as you'll find out, the main question that people ask if they don't lift is "What do you bench?"
You'll still need to pick a good pulling exercise. Pendlay rows, DL, Snatch Grip High Pull, etc.
