For "upper chest" training, etc. I present to you EMG results and information here:

Personally, I find that I get a much better contraction, pump and "squeeze" when I do an incline cable cross type movement than compared to simply doing barbell or DB inclines.
Amazingly, decline activated all 3 muscle portions of the chest best in the EMG results and MANY people overlook decline work thinking it targets only "lower chest" which is incorrect.
Inverse = decline
I'm going to go ahead and award myself best post of this thread and put this baby to bed.
Nothing that I saw in this article that would suggest anything about exercise selection order, loads, progressions, sets, reps, recovery or duration of a routine (weeks, months, etc). All of this makes a difference in terms of effectiveness when programming. Is the a decline going to be the only exercise then of course it's going to be the most effective exercise. But besides all that I have listed above, it come's down to genetics.
Since most bodybuilders (and it's been said MANY times on here by various individuals) that consistent programming isn't necessary, in other words, go to the gym and just pick random shit to do, this study isn't complete. Btw, I do understand this an EMG study. This is a 14 year old study.
