I have just finished this book, which is based off of a High Intensity Training method, and wanted the opinion of others. For me, the science and the theory behind HIT seems to be legit. I feel that the simple fact that Gordon LaVelle mentions HST and Bryan Haycock as having as legitimate theory and scientifically based training program (HST) only helps to add to Gordon's credibility. Still, I'd like the opinion of others on the forum here, or even Bryan himself...
