Please note: Exercise CDs do not contain audio or video files. They contain documents that should be printed for best results. Each document contains a series of still photographs and a text description of the motions involved. CD Images are available for downloading in ISO format. If you are not sure of how to convert an image into a CD disk, please do not buy the product in this format. Buy the CD disk version instead. Additional software is required to produce a usable product from a CD image. We do not sell or support such software. No warranty is expressed or implied. Refunds are not available for CD Image purchases. The buyer assumes all risk and responsibility for successful download and CD production. |
