Hi!
My rule of thumb is if I can do more than 10 reps I bring the weight up... If I can do only 6-8 at the new weight, I will do those 6-8, then bring the weight down and finish off my set ... next time I will do the same till I get to 10 or so, then up the weight again...
This is may be a little strange, but I LOVE to be SORE for a few days after a good workout... to me this means that it has been a VERY good workout! You can try Glutamine for muscle repair after a workout like that it helps a LOT with the soreness...
HTH...TTFN...
