RE: PECK DECK!!!!!!!
Completely agree with the others
Stick to bench and weighted dips for chest, good reps and high weight.
IF you need to preexhaust chest or want to do more afterwards, can do flies or pec deck, but no need at all in most cases.
My chest routine is:
3x6 weighted dips
3x6 flies (note these are after)
And in answer to your question, the pec deck hits the chest all over, just not the most effective method of getting it to grow.
