I think what is lost in this thread is the definition of "bulk"
when i think "bulking", the only person in this thread (from what i can see), that is qualified to talk is BtB.
weighing 150lbs and wanting to get to 170 is not bulking, it's working out. not that everyone has the desire to get huge, but adding a few pounds is not bulking.
but that's my opinion. talk amongst yourselves
