Most bodybuilders don't know how to train to build muscle and strength....They would be nothing without steroids/drugs....
It's a sport based on lies/falsehoods.
I don't think effective training principles are fundamentally different for naturals. It's just that drugs remove or reduce certain physiological limits. What would be the 'real' differences between the approaches wrt training?
That's truth.

I think some deliberately misunderstand the points made by the 'a calorie is a calorie' camp. 'Law of thermodynamics' and all that shit. Of course some believe in the 'insulin model of obesity' and other crap but I say there were no fat people in the concentration camps. People can't count calories, they may even be honest about not eating "much" but the perception doesn't correspond to reality. In controlled settings sluggish metabolisms and bad thyroid excuses disappear.
