My 2 cents for upper pecs...... Incline DB Presses (heavy and squeeze the crap out of those pecs at the top),Incline DB Flyes (heavy and DEEP),Low Pulley Cable Crossovers (meet your hand in front of chest and squeeze up to chin level).... great upper pec workout. Throw in some Flat Presse and Pec Dec Flyes...... awesome chest workout! Remember, if you ain't doing at least 20 sets per muscle group...you are wasting your time. Missing out on some great gains!! Eat Big and Train Bigger!
depends on who u ask.... if u ask dorian yates he will tell u that declines are the most effective muscle building workout for ur chest.... u ask someone eles they will disagree... who is right who is wrong... the guy is a 6x olympia.... never the less u gotta do what works for u... yes incline is effective it makes it so ur chest doesn't sage but it is up nice n tight under ur chin.... kinda how we like our womens pec.... bottom line is u gotta really figure out what works for u... only way is trial and error.... some people would also argue that the chest no matter what u do is working all 3 parts so it really doesnt matter... there are alot of different theories and explanations for these things...
What really works for me (upper pecs are a weak spot) is incline smith machine presses followed by flat bench presses but I lower the bar to my upper pec/neck region. After that i do flat bench flies, followed by incline machine presses and then i finish off with incline flyes and dips. I know, it sounds like it is too much but that's what works for me.
I never do decline presses because i don't feel my chest working.
try doing flat bench but with a reverse grip. Lower slowly then push up in an arch towards the rack... Sounds counter-intuitive I know but just try it. Mix it in with incline presses and the flyes really develop the area around the clavicle.
