Apparatus for stance improvement includes an aperture which may have optical sight therein, located in the grip or shaft of a golf club so that the ground or light is visible to the player when the club is properly aligned, the player's feet, knees, hips, and shoulders are properly located; and the player's head is in the correct position to hit a straight golf shot with an iron or fairway wood on which the golfer's downward line of sight intersects the club grip or shaft. The aperture is positioned at the point of intersection between the club grip or shaft and the line of sight. Several such apertures may be formed in the shaft and/or grip to assist the golfer in addressing the ball for different golf shots, such as a straight shot or a draw or a fade.
