I bought the book, Exercise for Better Bones, and also the accompanying exercise program which you buy and download from her website. They are designed to work together. I believe one purchase allows you access to each level of her program, which gives you a daily program of exercises. I did a 6 day a week program, with 3 different sets of exercises done twice each week. There are also video clips of her doing and explaining most of the exercises. I was quite dedicated for 4 months or so, but now I mostly integrate the exercises into my own daily mix of exercises and videos for variety. I learned a lot from the program and find it a valuable resource.
