As someone who has always played sports and liked to weight train for enjoyment, I found this book to be very helpfull. For anyone like me, who has been around gyms for years, knows the basic techniques but has got a bit bored of the same old excercises - THIS BOOK IS FOR YOU! It breaks down the body parts and has multiple excerises with descriptions and start and finish photos. It then has exercise variations and informative training routines of past body builders, giving a good guide to what you need to train and how often. If like me you only have time to train 3 times a week, it will give good routine variations so you don't get bored. An excellent buy!
