The concepts are great…sort of like a recipe with good ingredients but not the right amounts of spices and poor cooking methods. You need to find out what order is best for you and what amounts are good. I have the book in my collection.
One concept that many agree with is the use of mulit joint lifts and the elimination of leg extensions. He also got into posture and core strength. He has a great outline of what you need…just the flesh is too “phase” like.
He has alot of interesting exercises which can expose weaknesses in the athlete. I use his first phase exercises as supplemental exercises after the core lifts have been done. They are also excellent for rehab purposes.
