Abstract: The invention provides an exercise apparatus that is three-dimensionally adjustable to mimic sport-specific motions to enable a user to enhance neuromuscular coordination and develop sport-specific muscles. The apparatus provides unilateral or bilateral exercise. The apparatus has at least one cam assembly that rotates about the x-axis. Each cam assembly has a rotatable cam that rotates about the z-axis and is tensioned in one direction. A handle that rotates about the y-axis is mounted to the face of rotatable cam. Optionally, the apparatus has an adjustable height. The invention is also a method of using the apparatus to develop sport-specific muscles.

Abstract: An apparatus for strengthening hand, wrist, forearm, and shoulder muscles, thereby increasing performance and reducing the risk of injury in sports that utilize a swinging motion, such as golf, tennis, or baseball. The apparatus is also used to rehabilitate injured muscles and connective tissue in the wrist, forearm, and shoulder. The apparatus consists of two cam assemblies connected to a extensible support that has an adjustable height. The cam assemblies are adjustable relative to the coronal plane of the player's body and each comprises a support, a rotatable cam, a handle, and a resistive band. Each handle is adjustable relative to the sagittal plane of the player's body. The ability to adjust the apparatus in three planes means that a player is able to focus on the development of sport-specific muscles by adjusting the apparatus to mimic the swing used for a particular sport.
