it's a good program not only for "maximum growth" -- i've done it twice and i'm not a huge man girl -- but just to increase strength in general. i tweak some of the repetitions and exercises but it gives you a nice idea of what to put into your lifting workout day by day to work all of the muscles in your back, chest, and/or legs.
i usually use this workout for when i don't feel like coming up with something on my own, that and if you have an idea of what you're doing you can incorporate what you really wanna focus on. it also doesn't have you doing the same things for each chest, back, or leg workout. each time you come to legs for example, it has different variations for each muscle groups and even incorporates drop sets and super sets.
drop sets - workout sets where the weight is dropped with each subsequent set. your starting wait should be a failure weight or basically the max weight you can do
super sets - sets of exercises to work opposing muscles, ex. triceps and biceps
so i'm going to do back today and here is what a typical set up looks like:
