Not enough information to determine.
He's just parroting low quality information and his little exercises that he does while walking around the gym doesn't support the information. So it's quite probable he's just a grifter.
I got a homie like that. He works out about 3x a week. His body ain't insane but he's in shape and he can put on a shirt and pimp information. He's not a trainer, not a nutritionist, doesn't study, doesn't have an actual interest or educational or knowledgeable background about fitness so his information is not in sync with his lifestyle but he could easily put on a tank top and say shyt like "working out is good, but eating better is more important!". Or make one of those cheese videos "use these 5 exercises to chisel your chest". And particularly say some shyt like "dm me for more information" or "hit my patreon or cash app just $5 and I'll put you on"
