Query: Cultivate New Habits

I really enjoyed this book. I just completed the 28 day workout. If you have been living a completely sedentary lifestyle, you owe it to yourself to get this book - and do what it says. The photography is excellent and if you just follow along, you will be surprised at the changes you can make in just 28 days. I am not saying that you will be a black belt or anything close to it, but you will be on your way to a new lifestyle. This book SLOWLY lifts you up from the couch and enables you to create new habits for yourself in just 28 days. The initial "workouts" take just a couple of minutes and they build every day by adding a new exercise or stretch. Every seven days is a review of everything you have learned to date. By the end of the month (28 days) you are feeling better about yourself and just feeling better in general.
