Honestly, I can answer this one pretty easily- I know Preston Greene- he is the head strength coach at UNCC and I do the majority of my training over there- Preston was one of C.P.'s best students.
One of my best friends and my training partner coaches the long jump and triple jump @ UNCC, and has learned many of C.P.'s techniques through working with Preston, and has passed a lot of them on to me......C.P.'s training techniques and supplementation recommendations have not only taken my training to the next level strength-wise, but also athletically as well- his techniques carry over phenomenally to functional strength.
Long story short- GET THIS BOOK- you will be glad you did!!
PS This is coming from someone who has no vested interest in this product- I have just seen what C.P. techniques can do for athletes first-hand- UNCC has some of the strongest athletes in track and field!!
