The Body Jac was a product by a salesman who didn't look like he used it much named "Cactus Jack" from Des Moines, IA. Pitched as a device that would help make pushups easier, Cactus Jack hooked both Kevin Harrington and Barbara Corcoran with his little product.
The product that was demonstrated was just the prototype by good ol' Cactus Jack showed how it could be modified to adjust the resistance. He also estimated that it could sell for between $89 and $129 per unit, which is quite the range.
Cactus Jack spent $27,000 to develop the Body Jac.
