This manual for the Wonder Tummy Toner Exerciser, Model 6060, is a representative example of fitness equipment produced during the 1960s. Manufactured by General Home Products Corporation of Pennsauken, New Jersey, the device reflects the growth of the home exercise market in the post-war period. The original assembly and usage manual, revision 7-77, provides documentation of the machine's construction and intended use. Diagrams (Sketches A, B, and C) and a parts list detail components such as the rear frame (item 1, part number 33551), front frame (item 2, part number 33552), sheet metal screws, machine screws, wing nuts, end caps, foot rest assembly, U-shape bracket, wheels, rivets, and push caps.

The manual illustrates the equipment's operation with a female model demonstrating the exercise. The model kneels on the padded rolling platform, grasps the handlebars, and extends backward to a full leg extension before returning to the starting position. The instructions recommend starting with 5-10 repetitions, with the intention of strengthening the abdominal muscles as well as engaging the shoulders, arms, legs, and buttocks. The Wonder Tummy Toner exemplifies the trend toward affordable, in-home exercise solutions during the mid-20th century. The manual includes a caution to consult a physician before beginning any exercise program.

The included manual exhibits age-related wear, including creases and discoloration. General Home Products produced a range of household goods and exercise equipment, and the Wonder Tummy Toner is an example of their contribution to the fitness equipment market.
