High intensity training the mike mentzer way. You should really read a couple starting with the granddaddy arthur jones(i dont think he actually published a book but the colorado exepriment is an interesting read) and continue to read what others recommend. I find that as an instructional guide, mike mentzer is unparalleled as well as in his analysis of why his way is the best, with that being said, i train using Dorian Yates' split which to me lends itself better to individuals with better recovery such as those of us on aas.
