I had one of Dardens books. I think it was called New High Intensity Training. It was pretty poorly written. I was expecting Dr. Darden to produce factual data, peer reviewed studies, something along those lines. But it was a lot of fantasy. Almost hero -like worship of Jones. A rather naive account of the Colorado experiment, an offering of every excuse in the book as to why the results of the colorado experiment couldn't be replicated.
Even some absurd analogy regarding a gorilla Jones owned and comparing the activity level and diet of the gorilla to HIT trained athletes as proof of HITs effectiveness.
Plus the cheap shots against Arnold. He actually asserted that Arnold didn't know how to say his own name until Art Jones told him how to pronounce it. All in all it was a blatantly biased and poorly written book. A waste of money
