Dude, you are skinny and clueless yet asking tons of questions you aren't even ready for. How did someone at your stage come to the conclusion that they needed to add in upright rows because they needed more weight?
Find a program, stick to it, gain 30 or 40lbs and come back when you are ready to make some real progress. Between this and your other threads, all you are doing is wasting our time and your own.
Any luck yet getting those arms bigger but staying at the exact same body weight?
Let us know how that works out for you.
