A few days ago I hit 405 for 9 reps on the deadlift. Not dropping the weight and leaving on the floor. According to Wendler's calculator that gives me a max of 515. If I consider that 9 reps about 80 or 82% that makes it about 500. I really wanna hit 500. So much I left for a week later a little competition I talked about in here a little while ago. I have tested maxes before but I would like to receive some advice because it will be all or nothing here and I don't wanna fuck it up. Some people try adding 8% in the last warm up sets, that are actually singles. Would this be fine? 290x2 355x2 405x1 455x1 500x1-new max ?? Or maybe the 405 make it a bit lighter? (and the ones before too). I know I cant look at powerlifting as a reference since it will be different. I wont squat and/or bench before. I just wanna finally pull the 500.
