Body for Life: 12 Weeks to Mental and Physical Strength 
The three-times-a-week weightlifting program in Body for Life is deceptively simple. If you've spent any time in the gym, you've already done all the exercises. But Phillips includes a couple of high-intensity sets at the end of each exercise that should compound the training effect on each muscle group. Same goes for the cardiovascular exercise he recommends: just 20 minutes, three times a week. But those 20 minutes are spent jacking the intensity up and down, accomplishing more in less time.
Phillips arranges all this into a 12-week program, along with nutritional and motivational tips. Be warned that the nutritional advice gets a little spacey. For example, he puts "carbohydrates" and "vegetables" into separate categories, and recommends three daily doses of a nutritional supplement called Myoplex, which his company manufactures. (Fortunately, he gives tips on how to make each dose taste different, such as by adding drops of peppermint extract.) Despite this strangeness, Body for Life still motivates because so many others have achieved astounding results in similar 12-week windows, and the pictures and testimonials are here as evidence. --Lou Schuler
Reviews
Bill Phillips also has the guts to be honest and say that this workout does not fill the bill as an easy, quick fix thing. You have to stick with it; it's hard and takes discipline.
However, as other reviewers have explained much better than I could, yes, he does push his supplements in the book. This is why I don't give the book 5 stars. I recommend The China Study by T. Colin Campbell, Thomas M. Campbell II, John Robbins, and Howard Lyman for a more researched viewpoint on what foods bring vibrant health.
It's a wonderful exercise to strengthen your body and increase your metabolism, so that you can earn that body you want.
Easy to listen to and follow; it's great guidance.
