It's probably an extended version of the Real Fast Fat Loss workout judging by some of the reviews I've seen - some heavy compounds and metabolic circuits in combination to create a very tough and anaerobically demanding workout.

I'm vaciliating between recommending that you buy Alwyn's stuff, just try RFFL to see if you like his workouts in that style, and pointing you at the Warp Speed fat loss that I'm thinking of getting myself.

 I have a good idea what's in the program just from the authors and I like their style in general. And it's nice to not have to think so hard to come up with balanced workouts on your own, but since I haven't actually read the books I can only go by having liked what he's done in the past.
