the best powerlifters are all lean. efferding, konstantinovs, jamie lewis, dan green, that potato looking bloke who just squatted 1015 raw. same in oly weightlifting, with the exception of the superheavies - but oly lifters don't need a huge amount of muscle. look at hyusen pulaku - snatches 160kg at 85kg BW and he doesn't look like he lifts, just insane speed and technique.
