Abstract: An exercise device for developing various parts of a user's body. A coil tension spring is attached and extends between a pair of cuff strips. The cuff strips are secured into loops by Velcro fastening strips for receiving the wrists and ankles of the user. An elastic cord is attached to metal rings and extends within the coil spring for limiting the separation distance of the cuff strips and to provide increased resistance as the spring is stretched. The spring and cord are secured on the cuff strips with metal rings which extend through loops formed on each of the cuff strips by a reinforcing strip of material sewed on the cuff.

Abstract: An exercise device for improving muscular tone, primarily of the upper torso and arms, is provided wherein circular motion is imparted to a pair of hand grips rotatably secured to an eccentrically weighted cross shaft. Sufficient tolerance is provided between the cross shaft and the hand grips so that the cross shaft is free to move in an orbital path eccentric to the center of said hand grips, wherein the orbital movement of said hand grips and the eccentric orbital movement of said cross shaft may be utilized to exercise various muscles of the body.
