I remember when this came out and gave it a whirl, hell anything different is worth giving a shot. Nothing wrong with the program, like many. It's just taking compound exercises with short rest intervals and running you through. It'll kick your ass until you adjust to the swing of it all. If you haven't been into weights in over a year I'd ramp into it over the first month.
Document it all and when you find you hit the plateau shift the gears around.
