ABSTRACT:
An exercise device for strengthening the hands, wrists and forearms includes a main body providing a hand grip and an arm member linked to one end of the main body by a ball joint assembly to allow pivoting movement of the hand grip relative to the arm member. A selectively adjustable drag assembly imparts a variable controlled force of resistance to the rotational movement of the hand grip about a central longitudinal axis. The exterior of the main body is formed of a resilient rubber material, such as a spongy foam rubber, and is textured to include segmented ribs to simulate a hand grenade shell. A flexible strap with a releasable fastening mechanism attaches between a distal end of the arm member and the user's wrist to effectively anchor the arm member to the user. While grasping the main body, the user turns his/her hand forwards and backwards in a rotating motion against the resistance of the drag assembly.
