What is the best way to do pectoral stretches?

I would look at some of the stretches used for swimming, and while the pectoral muscles play some part in posture, one of the major causes of slouching/rounded shoulders is over development of the front deltoid compared to the rear deltoid. This is extremely common in swimmers, and can often be seen in people that emphasize front muscular development and neglect rear development.
