Apparatus for exercising the forearm muscles responsible for movement of the hand at the wrist. The apparatus comprises two rigid rings adjoined by, and allowed to rotate about, the axis of a central, cylindrical variable resistance mechanism. The rigid rings each support a handgrip that is allowed to rotate about the inner circumference of each ring at variable resistance settings set with a peripheral resistance mechanism including an externally threaded terminal end of each handgrip, a knurled sleeve with internal threads at one end and external threads at the other. The knurled sleeve can be rotated about the axis of each handgrip, through internal threads of the inner ring, into the inner surface of the outer ring thereby creating a desired frictional resistance. The desired resistance can be preset and returned to through the incorporation of click-stops.
