CUTLER Says I go by feel. I don't really pay attention to how much weight I use or to doing specific increments. It all depends on how I feel on a particular day. I do generally stick to eight to 10 reps for all working sets. The key to biceps training is to make the weight feel heavier than it really is by contracting your
biceps throughout each set. I used to curl 225 and my shoulders were doing all the work. I think a cambered bar is better than a straight bar because it allows the movements to be a little more fluid and true.
