Going to a 3 day split has helped quite a bit.  Pretty much just sticking to compound movements, no isolation and I've been able to pinpoint some areas of weakness.  Left shoulder, mid back and core are the areas I need to work on.  Probably a good thing too, since I have crappy posture and can address these issues at the same time.  Or maybe it's because I have poor posture that these are weak...doesn't matter, needs fixing anyways.
