Abstract: An exercise device for exercising an individual's hand and forearm while grasping an object is provided. The exercise device includes a resilient body member dimensioned to be compressively gripped with the hand of the individual and having a bore extending through the resilient body member and a slit extending from the bore along the length of the bore such that the resilient body member is selectively movable between an open position and a closed position. The diameter of the bore is dimensioned such that the resilient body member frictionally engages the object when the object is positioned in the bore while permitting sliding movement of the resilient body member along the object when the resilient body member is in a noncompressed condition and such that the resilient body member frictionally engages the object and prevents slidingly movement of the resilient body member along the object when the object is positioned in the bore and the resilient body member is in a compressed condition.
