But they lift multiply to compensate for their fatness.  And I'm not totally convinced that their gigantic bellies don't give them an advantage in the squat.  The things I've seen in my weight class (84kg) would piss most people off.  I actually have a meet this weekend, and my flight is the 84kg and unlimited class.  I have a feeling there are going to be a bunch of obese "strong" lifters.  They might be able to pull more than me but my Wilks score will always beat theirs.
