An elongated lightweight exercise device employed by the user to build and strengthen the muscles in the arms and chest area, comprising a short straight section of helically wound cable and two handles, one disposed at each end thereof. The wire rope may be coated with synthetic resinous material. Each handle comprises a hand-width long section of pipe enveloped by a plastic or foam grip with which to grasp the device, and a flexible strap with ends rotatably attached to each end of the pipe section in looped relation to the associated handle. To operate, the user inserts his hands through the straps and firmly grasps the plastic handle grips. Two equal and opposite inward forces are exerted on the handles by the user which causes the cable to bow under flexure stress. The user then allows the cable to return to its resting position due to the memory of the cable and repeats the procedure as appropriate. Repeated flexure over an indefinite interval of time does not incite fatigue in the cable. The straps guard against accidental loss of control of the device during use.
