how many differnt exercises should you do for each muscle in one work out if your trying to bulk up...

so far im doing 2.....
ex..bench press then chest fly .

DEAE:

That's how many I complete as well. IE Bench and dips, pullups and bent over rows etc.

I also mix it up. If I do flat bench on day 1, I might do dumbell incline on day 2.

i agree, 1 or 2 is more than enough. i do bench and dips also.
