I'm on the fence with this book. It's a six-week program to get you to increase your walking. For the first week, slap on a pedometer and forget about it! That's right. Don't do anything different because you want to see how many steps you normally take in a day. Each week you want to increase your steps by 20%. It even suggests "little" things like make sure your washer and dryer are in the basement so you'll have to walk up and down the stairs. That only works if you don't live in a rancher. Use the stairs instead of the elevator. If you take public transportation, get off an earlier or later stop. Common sense. The thing that pissed me off was the lack of pedometer recommendations. Only one for the Digi-Walker by Yamax. I've tried those little square pedometers and I can never open them or I've broken the plastic clip. I bought the Omron HJ-112 from Amazon for about $20. I've had it for over three years. It keeps track of the past 7 days with steps walked, aerobic steps in 10 minutes or more, calories used, and miles walked. You input your height, weight, and stride length and it'll do the rest. It comes with a strong plastic clip that you attach to your belt/hip and a tether line with another plastic clip that finally broke on me. Easy to replace with a metal clip from those key-holder/badge things people wear around their necks. The batteries cost about $10 for two and I've had to replace them yearly. It'll give you enough warning to replace them. You can even put this in your pocket or bag and it'll give you an accurate count! And, UNLIKE those little square pedometers, it doesn't confuse the motions of a car, train, or bus with walking. Think about that when buying a pedometer.
