ABSTRACT:
An exercise and/or physical therapy device which has legs for self-retaining the device on a human body adjacent to the muscle to be exercised while the muscle is being exercised. Each leg is configured to adhere to the body so that the device is retained without further manual assistance to stay in the position where the user initially places it. One leg embodiment is weighted and cone-shaped with a non-skid surface. Another leg embodiment is U-shaped and bendable. The device includes a flexible, slightly arched, hollow tube containing multiple fluids having different flow characteristics when the tube is moved.
