I am currently 5'10" around 198lbs. I can rep 405 for 5. I have pulled 455 for 2. I haven't trained much on DL, I guess i'm just naturally a good puller (long arms). Yesterday i pulled 500 after doing 5x5 for 185,225,275,315,365, 1x3 405, 1x1 455. I'm sure my form could use some work. If anyone has some helpful hints or tips to get me in the 600's with some training, it would be greatly appreciated. Also, I'm currently doing a Bill Starr routine to build core strength. By the time i DL on Wednesday, I've already done two squat workouts and weighted hypers.
