yes it's true some things will work for some people and some things wont work for some people, BUT, we all have to remember that Mike Mentzer claimed HD was the "one and only valid theory" and that everyone else was wrong and he was right!

theoretically HD is a load of crap that flies in the face of exercise science and empirical observations from oh the last 100 years or so.

btw, he's using more exercises than Mentzer advocates so it is not a "full blown" HD program.
