Dude looks pretty built in that pic. He's not a mass monster obviously.
Once again, BBing and working out is not always about how big you actually are. It's the illusion you create with your genetic shape, tie-ins, proportion symmetry and all that kinda shit.
How big do you really think he is there, Mak? First you say he's pretty built, but continue saying he's not a mass monster...which one is it? How can you tell from a photo of him standing alone (with nothing to show how big or small he is) how big or small he actually "measures"? You can't. Guy could weigh a buck fifty in that pic, but looks bigger due to how lean he is.
He doesn't have a lot of veins, bulging muscles and hardness. He's really just a fit looking guy with a six pack lacking striations everywhere else.
