English: Zander Type C-8 Adjustable Weight Lower Torso Twist Unit" is very similar in appearance to the type C-7. A U-shaped velvet seat is attached to an enamel iron base with a leather padded wooden brace resembling a bicycle handlebar mounted on an iron rod behind the seat. The device has a horizontal gear under the seat attached to a vertical gear via a chain. Parallel to the second gear and connected to it via a steel rod, a third gear is attached to an adjustable weight, the end of which can be attached to any one of 6 positions on a triangular iron bracket behind the entire machine. Both bracket and machine are mounted on an oak platform for stability. All of the iron parts are enameled black with gilt trim. After the handlebar and seat heights are adjusted, the user sits with his arms along the handlebars, which are in a stationary position. His upper torso is thus fixed, and his lower torso turns to the right or left, as prescribed, to exercise dorsal and abdominal muscles.
