I still to this day go back and read some of the old nautilus bulletins - and I'm always struck by how much different they are then what the average muscle heads "stereotype" of Arthur Jones' HIT seems to be . I think that Mentzer really had the most to do with taking Jones' Ideas to a ridiculous level.
Arthur was actually a proponent of 3x/wk full body training for the average lifter - in fact the last paragraphs of bulletin#1 could easily have been a "rough draft" of HST, I quote:
"in almost all cases, best results from heavy exersize will be produced by the practice of a very limited number of compound exersizes that involve the major muscular masses of the body, and such training should be limited to no more than five hours of weekly training in any case and to about four hours in most cases.
In practice best results are usually produced by three weekly workouts of less than one and one half hours each."
I really do think that when most scoffers think of HIT and Jones they may be erronously thinking of Heavy Duty and Mentzer .
I shudder to think where we'd be today if Jones and gironda ( and later Yates ) hadn't come along to "counter-balance" the strangle hold Weider and his principals had on hypertrophy thinking in general.
Here's a link - to the nautilus bulletins , check them out you may be suprised at how sane he was.
