ABSTRACT:
A stretch exercise device is molded in one piece of a material having the physical properties of a soft, flexible, deformable rubber. Two elongate, spaced apart side members extend along a long axis. Many finger grips or rungs are arranged parallel to one another attached at their ends to the side members. The rungs are spaced apart by a distance small enough so that a hand grasping a first rung may reach out with some fingers to reach an adjacent rung without first releasing a secure grip on the first rung. This enables a user to exert continuously increasing tension in stretching exercises. Grooves on the rungs and grooves on the side members provide finger gripping surfaces to facilitate this progressive tensioning movement.
