I have all of Suzanne Andrews DVD's and love them including this one. She really understands people who want to be kind to their joints and I'm one of those people. I love to be active, just not into overdoing it. Bone Builder gives you a good workout without overdoing it and I love Suzanne's uplifting attitude. The DVD goes at a gentle pace showing you how you can use stuff around the house as weights to help make your bones thicker. I started out doing the seated exercises, but now I can do all the standing exercises. If this is too easy for you you can use heavier dumbells, which is what I do now. I use 5 pound dumbells and 8 pound ankle weights and I feel like I got a good workout in just 25 minutes. Not too much to take away my energy to get through the day. I got this awhile ago and alternate it with her other DVD's. I've been doing long enough now to know how to do the exercises so I opt to do the bonus section where you can't hear the instruction just the really terrific music. Also like how I just press (>) and I miss the introduction and the DVD goes right to the beginning of the workout. Don't need to listen to that anymore. On the other hand if you're young, in really great shape and/or like rock or hip hop music and want a hard sweat pounding workout, you probably wont like this DVD. I'm over 50, heavier than I used to be and I prefer a more gentle paced instructor now who uses a plesant tone and that is how Suzanne teaches.
