Well, I guess that I got a pretty good body using a few of the principles of HIT, namely HIGH-INTENSITY and LOW VOLUME, but I did train rather frequently. After a while, I really lower the frequency to once or twice a week and even lower volume, and I basically looked like sHIT lol So I can only assume at that point in my training I was actually under-training and certainly de-conditioned. But, one question remains in this puzzle, and that it how much did my aerobic training have to do with my rather decent body? When I cut down my frequency I also cut out my aerobic training/conditioning.
