I'm at the same point you are. I'm in my second week. The first week...I only did 2 sets of each. I've been able to bump up the set to the 3 sets that are actually in the work out.
The way I see it, you have to listen to your body. A little soreness is one thing, but if something really hurts...ummm...don't do that!
If your concerned about bumping up, keep the weights the same and stay at that level until you feel better about moving up the weights.
ps - I'm not a trainer though...so this is just free info....if you want real science...you might want to wait and hear from an expert.
