So, reading the thread about the incline press got me to thinking about an exercise that I made up that is super effective for hitting the upper chest and anterior deltoid. Plus it's got the added benefit that people will look at you with that "what the hell are you doing" look...
This seems to work best with a hammer strength incline press. You begin by sitting sideways on the seat. Sit so that the handle is right next to your sternum. Grab the handle close to your chest. Situate yourself so that your shoulder blade is pressed against the back of the bench (as opposed to your shoulder). Then press! Simple as that Start with much less weight than normal to guage your capacity. This isn't as easy as normal incline press.
It seems like you could duplicate this with cables, but I haven't had luck with getting the same pump as on the hammer strength machine. When I was doing this exercise my upper chest grew like crazy!
It may sound stupid/simple/easy/cheating/weird, but try it, you'll like it.
