Man that guy was a genius who does not get enough credit, if you ask most gymrats why do they go to the gym 6 days per week and why do they do 20 sets per exercise they cannot give you a logical answer, they will say well you need to train hard to get big you cant be a pussy.
Ok on a serious note, this is the most effective way to train.
Youtube has most of Yate's " Blood and Guts" training sessions.
I was ready to quit back in the mid 1980's from doing conventional higher volume routines.
I said fuk it and gave Mentzer's heavy duty workouts a shot.
I never did much juice, but I did some Winnie V to help me get ripped.
In 1986, I won 1st in my class and /or the overall in 7 npc shows.
