Looks like a hit a nerve! Not my intention. I have been a competive powerlifter since 1989. At 48 my best days are in the rear view mirror, however; I have gone 3X+/BW single-ply SQ & DL in several weight classes. I get the whole carring extra weight, and continue to do it to this day. It is the only way I could have gone from 160 to 235+ compteting weight. I 'feel you' STB, when a lifter has a 90 min. workout and 60 are spent on 'core' there is a problem. I see it all the time. However, many are carrying around an extra 50 without a clue how to put it to good use; and everyone with visible abs is not a pussy. If that's your deadlift with a hamstring issue, and you can move your bodyweight like that from weigh-in to the platform; you have it going on. Best of luck, I look forward to following your results.
