Abstract: A stretch-assisting device, adapted for mounting in a vertical orientation on a door, wall or analogous vertical substrate, features an upper framework portion and a lower framework portion, coupled together. Each framework portion consists essentially of hollow rigid tubing arranged in a loop shape, with attached metal rings which project horizontally. Through each plurality of metal rings, an elastic cord is threaded, and joined to form a loop. Once the device is mounted on the substrate, a person can rest a body portion, such as a heel or elbow, on a selected segment of the elastic cord, and begin to stretch a muscle or tendon associated with the body portion. Since the cord is somewhat yielding, triggering of the myotatic reflex is avoided, or at least delayed, thereby facilitating completion of a stretch. A user can also secure an audiovisual playback device adjacent the device, in order to inform the user during stretching.
