He looks about 7-8 % , maybe 225 lbs.
Can't compare to Arnold- Arnold was a freak with hollow bird bones. I'm his height and weifght and don't look as huge as he did , either. and no I'm not fat (maybe 10-12% at the moment)
He LOOKS bigger...till you see someone in person...you never have any concept as to how big that they really are. I have a friend who weighs 242 but LOOKS smaller than LL...
