Abstract
Abstract A device for use in contests in which two contestants attempt to force one another's forearm from a substantially vertical position to a substantially horizontal position. The device includes a base for resting upon a supporting surface. The contestants sit on opposite sides of the base, facing one another. A first arm is pivotally mounted to the base in a manner so that one of the contestants can grip the distal end thereof with his elbow resting upon the base and with his forearm in a substantially vertical position. A second arm is pivotally mounted to the base in a manner so that the other contestant can grip the distal end thereof with his elbow resting upon the base and with his forearm in a substantially vertical position. The first and second arms are fixedly attached together so that when one of the arms is moved downward, the other arm is forced downward. The contestants attempt to force one another's forearm to a substantially horizontal position by moving the distal ends of the arms downward in opposite directions.
