Every single one of these people are on steroids. The human body is not biologically able to recover from that much strain in such a short amount of time.
Nobody walks around with 7-8% bodyfat, lifts over 300 lbs and runs several endurance performances in 1 week without the help of serious amount of drugs. No amount of training is going to overcome the neurological limitations that the human body has.
At one point they comment on "you can't look at a person and see if they are on steroids", but you can look on their numbers and realize that they are. Compare what they are doing to Olympic athletes and you'll see that they are often putting in as high or higher results than olympic freaking competitors. And the Games is the golden standard of steroid use. The Olympics is often a state-sponsored doping program. And here we see a privately founded circus for performance enhancing drugs.
