OK, people are saying you cant work UPPER chest. You can only work the whole chest. On this pretty extensive site, it lists a starnal head (http://www.exrx.net/Muscles/PectoralisSternal.html) and a clavical head (http://www.exrx.net/Muscles/PectoralisClavicular.html) with the clavical head being the upper chest. Both have diagrams along with extensive information. Check it out and tell me what you think. I think this pretty much proves you can work upper chest.
