Abstract: A portable elastic exercising device which may be worn by the user to tone or firm up the wrist, arm and shoulder muscles while exercising not only in the conventional positions of standing, sitting, or lying, but more specifically, since the device is completely independent of the need to be anchored to a fixed object, it thereby permits the user to exercise while walking, running, or jogging, and has a single length of elastic cord that is twice passed through a flexible sheath to encompass the user's waist and whose two ends are also enclosed inflexible sheaths to form handles. Handle loops are maintained by covered steel wire ties or other fasteners.
