Abstract: An exercising device for strengthening and developing the hand, wrist, forearm and pectoral muscles. The device includes an elongated rotating pin having a central portion with a circular cross-section and gripping portions located on either side of and coaxial with the central portion. The central portion is received by a clamping mechanism which is held stationary by a mounting apparatus. The clamping mechanism includes an adjustment for varying the frictional force exerted by the clamp on the rotating member. Further included is a laminated liner disposed between the clamping mechanism and the rotating member comprised of a layer of rubber and a layer of self-lubricating plastic.
