Marc Steubing is another retarded youtube bodybuilder celebrity.
Guys an idiot but crazily dedicated, I think he's been running for like 6-7 hours a day eating very little and throwing that little up.
But it's one of the craziest transformations i've seen.. 100lbs down in two months?
Probably ate all his muscle too but still.
