I found out about this handbook from my aerobic instructor. We use the stretch tubing with most of the classes. I immediately searched at Borders bookstore. Couldn't find it. Went online and found and ordered it from Amazon.com. I ordered one for me (a gym junkie who needs a stretch tubing routine for rainy days) and for a friend who works out at home with his home gym. We both agree that the handbook is very useful. The Great Stretch Tubing Handbook includes exercises that work each part of the body. If you want to maintain a toned figure the handbook is for you. It is not to be used for heavy "stretching". First there are a dozen stretches listed and displayed by a model. Then the exercises for: chest, shoulders, rotator cuff, back, biceps, triceps, forearms, core, and legs. The only equipment you will need is stretch tubing (or bands). The handbook explains how to make and use your door attachment. Each exercise (and stretch) is demonstrated by a model. You don't have to guess about how the movement is executed. Also, for those body-conscious folks, each exercise explains EXACTLY which muscles you'll work. Example: For the downward chest crossover: muscles worked = anterior deltoid, pectoralis major. pros: =low price =great photos =small enough to pack in a gym bag =easy to follow step by step instructions =general and specific descriptions of muscle groups being worked cons: =lots of instructions (for a newbie) =too small for someone trying to follow along (posters are available)
