No one can tell for sure except you. But generally, you should expect increases in strength and size, if you do things properly.

i dun really get it why u keep using muscle koyak orgasm?
tak paham wat u trying to say. =.=

Trapezius.

Shrugs

just go and google it up or looking bb.comf or the exercises.

It's NOT OK, the main reason is that it's only 3 meals/day and with that diet I don't think you even reach 3000cal a day.
More number of meals = higher rate of metabolism = more fat burning + more muscle building = 

6 MEALS/day. I don't know how you are going to do it, but 6 meals a day is a MUST. 3 meals a day is a no-no.

bad for rotator cuff?

Bad. Just because it's bb.com doesn't mean they don't make mistakes. Heh.

I'll reply your question with a question bro. Say you reached really advanced stages where you're pressing the 80 pounders or so for shoulders. Can you imagine rotating them? Imagine how bad it'll screw up your shoulders. There're people who swear by them but i seriously don't think we can't rotate them without screwing up our shoulders.
