Nothing to say against Jones and Nautilus.
I myself trained according to heavy duty system in the 70ties. Short and intensive units make sense.
As a novice I was very much impressed of this theory.
The experiment with Viator was interesting. But he only regained what he already had before. He didn´t start the experiment as a novice but as a top-bbler who had lost lot´s of his gains. The problem with the experiment is that Jones thought that 63 pounds within 3 month with high intensity training was caused by his machines and his system. No. It was the roids that made Viator grow like grass. And of cause the memory effect.
What Mentzer made out of this experiment compared to Arnold gains was – very politly speaking – wrong.
Over 40 years ago this experiment was thrilling. Today after so many years I know that something like this is absolutely normal. I have seen so many elite lifters loosing “all their gains” within a few month and gaining them back in a short period of time. They start training again and you can see their muscles grow. It doesn´t matter which training – “system” they use.
Again: I think Heavy duty and HIT are good. Make the Colorado experiment with clean athletes today and see what happens.
Cadillac and Levi's are the presenting sponsors of the series. The Cadillac name appears on the 30 for 30 logo, while the Levi's "go forth" slogan appears on the bottom corner of the screen during the directors interstitial comments, which appear for 45 seconds at the beginning of each film and 30 seconds at the end. Commercials for both companies were shown during every intermission during the original air dates, with Levi's guaranteed a 60-second commercial slot at the beginning of the third act. Cadillac replaced Honda as a primary sponsor; during its time as a contributor, Honda aired parts of its "Dream the Impossible" documentary series in the first commercial break.
