ABSTRACT:
An extendable and rotatable exercising device comprising outer and inner tubes which can be manually grasped and pulled generally axially from a collapsed position to an extended position. An elongated resilient element extends through the inner tube and is attached to the opposite ends thereof. The resilient element is prestressed and acts to resiliently resist movement of the tubes from the collapsed position toward the extended position. The tubes are relatively axially rotatable to allow the wrists of the user to be exercised.
