Abstract: An exercise device includes a left glove member adapted to be worn on the left hand of a user and a right glove member adapted to be worn on the right hand of the user, the left and right glove members each having an impact area and an elastomeric cord extending from a center of the impact area to a ball, such that the ball is connected to the left and right glove members by the elastomeric cords of equal length. A rigid plate member is fitted within each of the left and right glove members for providing a solid surface at the impact area. The user, wearing the left and right glove members, alternates movement of the hands in a repeated left and right punch throwing action which causes the ball to alternately strike the impact areas of the glove members and travel away from the user until the elastomeric cord leading from the opposite hand stretches taut and causes the ball to travel back towards the user for subsequent striking with the opposite hand.

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.
