I agree...I suppose I shouldn't have added the extra ten lbs. It's not an issue of weight though. During my third set, I could have pulled at least three more reps if I had wanted to. I'm confused about why I can do three sets without a problem and then I can't even complete the first rep of the next set.

I had planned on doing 315 during the workout, but the last time I did deadlifts it was very heavy. So I decided to do 305 for the first set to see how it felt. I haven't been doing deadlifts for very long, so I'm still figuring out the weight. Wouldn't one set at 305 and 4 heavy sets at 315 be better than 5 lighter sets a 305...especially if I can progress the following week at a heavier weight?
