The software product is comprised of an exercise program stored on a storage medium. The exercise program operates with a computer to display images demonstrating a random set of exercises on a computer screen in the following situations. The computer displays the images demonstrating the set of exercises when the computer user selects an icon on the computer screen, when a certain amount of time has passed since the set of exercises has last been displayed, and as a screen saver. The images demonstrating the set of exercises shows the computer user how to perform exercises that are geared to prevent and treat RSIs. The software includes a version that accommodates children, a version that accommodates adolescents, a version that accommodates teenagers, and a version that accommodates adults. Each version includes images that distinctly appeal to the respective age group.
