Brian has the complete opposite of bigorexia, he thinks he's huge. Normal clothes he doesn't look like he lifts, swims in his suits. Compared to an average man unclothed sure he's big and muscular but sees something completely different from the rest of us. Zane looks bigger and heavier, has more muscle and development on his frame, Hanky knows this, he's gotta be saying all this crap for a reaction.
