Ha! That's a classic floor lift! It's like a partial squat, with a dipping belt attached to a chain that goes around the barbell. Some oldies used to call it the "hip & back" lift.
I believe Bruce Randall is the man in that picture. He's got the weight all loaded up, and I must say that's quite a bit, WOW! Even for a partial squat! Impressive even for such a fucked up lift. Boy, Bruce Randall sure was quite the walking experiment...
