depends on how heavy they are
well for the top 85kg guys - 187lbs
Vanev has front squatted 255kg - 561lbs - although he only goes down to parallel. So his backsquat would be at least 600lbs
quote -
Dursun Sevinc of Turkey, now retired, could front squat 280 Kg - 616lbs ( this is shown in one of the iron mind tapes). back squat would correspond to at least 330Kg, 726lbs which is claimed to be the best of Dimas' back Squat. There is a training tape from 2002 ( Dynamic-Fitness) which shows Dimas doing a 250 Kg 550lbs in the middle of a workout with no spotters. It appeared that he could probably do another rep.
Ironmind sells a poster of Chakarov (91kg) squating a no-no-no triple fullbacksquat with 270kg 594lbs in 1993. It's on one of the early Ironmind tapes.
also 77-kg 170lbs Idalberto Arranda banging out 290kg 638lbs for a double after his workout. Also on an Ironmind tape.
Most of the top olylifters in any class seems to be able to do triples with over 400lbs, and guys around the 190-200lbs over 500lbs. Well it seems that way watching The Polish 2001 Ironmind tape.
For the heavier guys Botev squats 704lbs in one Ironmind tape after his workout as well. He cleans 250kg 550lbs, on one of the tapes so not a surprise
Leonid Taranenko claims 837lbs with a 2second pause at the bottom . He has clean and jerked 563lbs.
