Abstract
Abstract An exerciser consisting of only four small parts. A two position, narrow foot rest, two adjustable hand grips and a strong, small size nylon rope connecting the strips to the footrest. Completely assembled, ready for use, the exerciser weighs only about 4 ounces. When not in use, it makes a small compact package and storage is not a problem. By pulling on the hand grips and pushing on the foot rest it exerts one group of muscles against another group of muscles, involving the whole human body, providing a handy, practical, economical, efficient, effective exercising device. After this simple exerciser is adjusted to the individual, no other attachments or adjustments are required.
