No supplements, no steroids, and half of them don't even have sneakers. Hell, they're not even training in a commercial gym and look at the physiques!!! Then there are ppl with everything who can't look half as good as these guys. Genetics ? Maybe slightly, but also keep in mind there probably isn't a McDonald's on every corner either. The next time some twig thinks he needs 1,000mg a week of tren he needs to watch this....
