I first learned about interval training when reading the popular book The 4-Hour Body by Timothy Ferriss. I then experimented a bit with Tabata training and dipped a toe into the Insanity program, but I never bothered to read more in-depth about the theory behind these programs. This ebook has taught me more than just the basics. Backed up by theory, I have found the motivation to really give high intensity interval training a go. If the author had included some pictures, I would have given him a fifth star.
