I agree with the reviewer who said the routines require you to live in a junkyard. Unless you have 4,000 pounds of scrap metal and some railroad ties handy (and I'm not kidding), you'll be better served buying a solid, old school-lifting treatise like Brawn or even Super Squats.I sold my copy of this book on ebay.
