I sure hope you're right cuz my bench is down more than 20 pounds.
Figgs? You're apparently a young guy. If I read correctly, you trained "HIT" style for only a couple of months. If it only cost you a setback of 8 weeks and 20lbs on your bench, to discover you weren't gonna accomplish your goals, then count it a valuable lesson for a very small price...in the long run.
To his credit, Mentzer's style did it's job...FOR MENTZER! He obviously benefitted physically from his training, and then he did what I think most of us envy...he made a good living from selling/ teaching such concepts, virtually unopposed!
Part of discovering what works, FOR YOU, is finding out what doesn't work, FOR YOU, and it sounds like you're a step closer to understanding yourself. That's progress, that IMO, you owe, in part, to Mentzer.
Intensity and Volume are as similar and yet as opposite as the Right hand is from the Left. It is, again, IMO, that when the two meet in the proper ratio for the INDIVIDUAL'S goals, that success will be found.
You seem to have a dramatic form of writing, and a charasmatic personality. Don't pollute yourself, as some, by hating on a true pioneer of bodybuilding, just because his way turned out to not be your way.
Best of luck!
