A device for preventing or restraining the bending of an elbow. It is designed to be used by a golfer as an aid in improving his swing. A first elastic band encircles the arm immediately above the elbow and a second elastic band encircles the arm at the wrist. A resilient plate is attached to the first band and extends in the direction of the wrist. In one embodiment the plate has a hooklike end which engages a complimentary hook attached to the wrist band. Rotation of the wrist releases the end of the plate to permit free movement of the elbow. In another embodiment the wrist band is provided with a steel plate which overlaps and retains the end of the resilient plate until the elbow is bent a predetermined amount.
