He actually isn't "scrawny" have you looked at any photos besides the initial still in the video?
Additionally, do you know any natural bodybuilders? Have you seen them in their offseasons? They look like the average joe, and most of them are under 200 pounds.
Not trying to start an argument but what most people perceive as bodybuilders are very far away from what a lot of the natural bodybuilders looks like, especially the lightweights.
