i have one of Yates DVDs and i train exactly the same way he does, i rep failure.
Personally i did like arnie as a bodybuilder and what he did for the sport is fantastic. Although you do know arnie was on gear, in fact he was the person who made Dianabol so popular. (im sure thats one of the things he took) Dorian went under 1 drastic change to his routine, diet. He started taking HGH and got mahoosive. how do i know this? i used to train in his gym in birmingham with an ex powerlifting champion.
