    Abstract: Provided is a method of evaluating stability of a golf swing. The method comprises calculating a force indicator that represents a force that acts on a body of a golfer during the golf swing and evaluating stability of the golf swing according to a magnitude of the force indicator. In the calculating, the force indicator may be calculated during the golf swing made with a specific golf club, and in the evaluating, the stability of the golf swing may be evaluated as a characteristic of the specific golf club, in accordance with the magnitude of the force indicator.
