He's doing the old Continental lift. Helps to have a big belly, sort of like having a built in resting shelf because your dragging the bar up against the body. Than the push/jerk press overhead. The great Paul Anderson had done well over 400lbs 50+ years ago. Old time strongmen, in Europe ,also have done over 400, with the crudest of equipment. No drugs back than, just beer..and the belly.
