  • Patent number: 5040788
    Abstract: A golf exerciser comprising a handle to be manually grasped, a stretchable cord assembly attached to one end of the handle, with the other end of the cord assembly attached to a doorknob. The person assumes a golfing stance and grasps the handle in the lead hand (which for a right handed golfer would normally be the left side), and pulls the handle away from the doorknob, thus strengthening the muscle in the left hand. The cord assembly desireably comprises one cord of a shorter unstretched length, and a second cord of a greater unstretched length, so that there is a lead-in exercise motion with lesser resistance, followed by a power mode where a handle is pulled and rotated by the wrist to give isometric exercise.
