Great book with lots of information. Very to the point. This would be an excellent reference for triathletes. It's a very big and heavy book in full color with thick glossy pages. There are a lot of photographs depicting what he is trying to demonstrate. There are sections for running, cycling, and swimming, which details technique and form for each. He then details strength and conditioning and mobility. There are a ton of exercises and stretches, again, demonstrated with photos. He has a small section in the back on nutrition before going a little into the program of crossfit. I did not get the impression that he expects you to stop your training to add this in and he makes it easy to incorporate into your current program. I bought this and the Unbreakable Runner by T.J. Murphy. I gave that one away. Keeping this on my coffee table for quick access. I highly recommend if you are looking to add some crossfit type exercises into your routine.
