how much are you going up every week? i think that could be alittle dangerous.. when i was building i'd do a warm up set of 10, up the weights to 75% of my max and do 8, do my max as many times as i could, then 75% again, then the warm up weight until complete failure. only time i'd ever up my weight was when i'd do my max more than 4 times.
took me forever to get up to 215 for my max.. now i'm back at like 60 pounds due not going for a few months
