I've never used a walking CD nor do I know anyone who knows anything about them or has used them either. I would like to understand how this CD would be beneficial since we all know how to walk. Are there instructions about the walking pace, conditioning, etc, if so can you describe what type of activities you are instructed to do while walking around a neighborhood? What is the intensity? Is someone instructing the whole time you are walking or is there music? Are the walking instructions pretty much useless or very helpful? Do you use it frequently? If yes, is one better than the others? I know there are a lot of questions here, but I would like to hear your comments about what you liked or dislike about the walking CD before I run out and buy one. Thanks for all responses.
