A portable multi-purpose rack for use on exercise equipment is disclosed, having a transparent substantially planer surface with flanges extending at opposite angles from each end. The first flange is mounted upon the upper edge of the digital display of a piece of exercise equipment and the planer surface placed directly upon the digital display. The bottom flange forms a lip which holds a book or other object thereon so that the user of the exercise equipment may place an object or book directly upon the portable multi-purpose rack without obstructing the view of the display screen.
