Enormous gut. Zero visible muscularity. Literal bitch tits. Very estrogenic phenotype. He looks like your average alcoholic beer-drinker.
But he can lift a heavy bag of sand, I guess? Uh, good for him? Half of the lift is him supporting the bag on his protruding gut, lmao.
Besides, it could be bullshit. He doesn't weigh the bag and it could be full of anything at all. Youtube is full of fakes.
