However I have just looked at all of the exercise DVDs offered on Amazon. I've been looking for one that doesn't seem to assume that the viewer is 24 years old and already fit and slim. Further, I've been looking for one which also has good reviews. This is the best I could find. I suggest reading through these reviews (there are 4 pages of them) and then, if you're interested in buying it, clicking the 'This product' link at the top right of the page:
