Muscle Logic by Charles Staley
It covers the EDT system in depth with 5 sample programs. The book covers such things as how to set up an EDT program including sets, reps, rest intervals ext., ext... It also includs a sample athletic program, and a core conditioning program.
Now should you purchase this book? If you like the EDT system then yes, although it caters to the general fitness market, I still learned a lot from it. That is coming from a man who has read all CS's articles and newsletters on EDT (not to mention his other books).
