Dorian Yates followed a progressive training approach involving one set to failure per exercise, targeting each body part once per week.

“he was very uh I guess Progressive in even though he was really going back to kind of Arthur Jones and Mike mener and those guys but he was really just sort of doing one set to failure per body per exercise and he was doing each body part once a week”

“and that's why Dorian could do what he did”

“Dorian from what I understand did roughly 14 sets per week per muscle groupish and um that gets into that territory of a very robust signal of growth to the muscles it's not the highest signal of growth”
