Query: Great book but can be improved

Don't get me wrong, this is a great regimen to follow. The problem is, it requires complete dedication. You won't get the results promised if you only do the workout 3 times a week. I tried that and I gained nothing in 2 weeks. But when I worked out for 2 weeks, 5 days a week, I actually gained 2.5 inches on my vertical. I feel the nutritional instructions could also be improved. If I could do it all over again, I would NOT follow the nutritional instructions. It is not complete information. Because of it, I gained a lot of fat and is still not able to get rid of it. It is advisable that you know your physical limitations and adjust the program so it fits your physical abilities. Otherwise, I believe it is a very helpful book.
