Abstract: An exerciser for simultaneously strengthening the finger, hand, wrist and forearm, comprising a head section connected to a handle section. The head section has enclosed within its rigid perimeter edge a solid flexible material which, when the exerciser is in use, generates air resistance to twisting and turning movements of the wrist and the forearm. The handle section comprises two moving components positioned in facing opposition to each other on opposites sides of a shaft which is connected to the head section. The moving components are connected to each other and to the shaft by springs which cause the moving components to be spaced apart from the shaft. In use, the handle provides gripping resistance to the fingers and hand of the user. An elastic sleeve surrounds the handle assembly to prevent pinching of the user's hand.
