I liked Mentzer but he made the mistake of becoming a bit of an addict. I would imagine that H.I.T. would work if you were taking a gram or more or whatever it is these genetically pathetic individuals that poopulate the dais today are.
Genetics have a great deal to do with bodybuilding but you can "enhance" a woman until she is larger and stronger than most men and it ain't genetics that made that possible.
Mentzer admitted he took a LOT of steroids. They all took them back then and they all take a LOT more now and have done so for decades. I don't begrudge MEN that take steroids as more than a few of my friends did so in the 70s and 80s. They were still my friends. When steroids were made a "controlled substance" they were still my friends.
Men that take grams per week of all manner of bathtub brewed AAS are stupid. What was that idiot that killed himself and had a test level of 50,000+? Dallas McCarver? What a maroon.
Women that take male hormones can fuck off and die for all I care. Filthy fuquewad bitches. Yuck.
Train however works for you. Right now and for the foreseeable future I have to train with pathetically puny weights for high reps. Upsets me no end but I want to train and in order to do so I must be careful not to hurt myself. I have done HIT, Dinosaur Training, Rest/Pause, Volume, High Volume and Ridiculously High Volume styles of training.
If it works for me I train that method until it no longer works (for whatever reason) for me and then move on to something else. I'll be back around tho'.
