Here's the longer version:
I finished the first month and actually had pretty good results. Then I got sick and didn't work out for a week, then life got in the way and I kind of lost interest.
After the first week, I realized that I needed to modify some of the workouts to better fit my goals. This included modifying the chest workout to include heavy bench press instead of doing 800 different variation of push-ups.
The cardio-based workouts (Kenpo, plyometrics) were actually a great workout and quite a bit of fun.
Consistently working out 6 days a week is also a great recipe for results.
The bottom line, however, is that I just didn't really care for the majority of the workouts. They were all very repetitive (doing cycles of the same 4 exercises for an hour, the 2-hour yoga video, etc...) and I didn't enjoy them.
The principles are sound. Mix up the workouts, throw in plenty of cardio, eat right, and stay consistent. For someone who wants a "no-brainer", the program is perfect. I just feel like I know my body well enough to design a program for myself that I enjoy doing and gives me the results I want.
The problem there is that I've been a lazy sack of shit lately. Work and family life have been super busy and I've had a hard time keeping up with the "extras" in life. Hopefully things will be calming down here shortly and I can start lifting and xc skiing. And maybe even blogging.
