his entire channel is criticising other peoples training
Which is fine. Except he has no grounds or right to criticize others who look better than him, know more than him, and are more accomplished than him. And he thinks he's more knowledge than any coach out there. He has stated he could become an expert in any field that someone else excels at in less than a year.
You look worlds and worlds better than him. You are more successful in competitions than he ever will be. Any sane person would take your diet and training advice over his. His pre-contest meals consisted of chicken thighs, Gatorade, and cereal. If you trained him for a show, you would get him to actually improve. But he would never listen to you. Because he has stated that "if someone thinks they know more than him, then they can fuck off."
He has built a career and made millions off portraying himself as an educated, successful hard training bodybuilder. But he's not. He has never trained to failure, doesn't train hard, has placed horribly in all shows, can't get himself in shape, looked like crap in all shows, uses plastic surgery to get leaner vs dieting harder, and wrote a garbage PHD paper that should have never passed. Stupid head then lied and committed academic fraud to try and cover it up. Unfortunately for him, he was too stupid to even lie correctly. Hence, he got caught.
