There's one alteration Alwyn mentioned for "advanced" guys. His definition of "advanced" for the Afterburn program was to have attained a good level of leanness, either through something like Afterburn or whatever else...having established a certain amount of competence in losing fat.
Anyway, the alteration was simply this:
Before you do the high rep stuff, do a few sets of heavy, low rep work in the appropriate lifts.
Using the above workout as an example, you might do some heavy squats first, before you started the rest of the program.
