Those guys all used steroids. We talking bout how to build muscle naturally. Taking advice from steroid users is why the fitness industry is so fukked up and most people never get any results following their guidance.
You could sit at home in front of the TV eating pizza and if you're on steroids, you'll build more muscle than a guy who is natural and busting his ass in the gym everyday. Steroids are a cheat code and trying to get advice on building muscle from anybody who takes them is a waste of time.
There is a reason you never see guys who do calisthenics having that roided up look a lot of body builders have. Its not because calisthenics is inferior to weight lifting when it comes to building muscle. Its because most of the guys lifting weights are using steroids and its the steroids that is giving them those unnatural results.
What happens if someone does calisthenics and takes steroids?
