A golf-swing training device for improving ball-driving distance and accuracy. The training device mounts to a golf club and signals to the golfer when the club head begins decelerating in the direction of the forward motion of a golf swing. Additional energy is available for transfer from the club head to the ball as the club head is transitioning from acceleration to deceleration. This additional energy comes from the change in the direction of the flexing of the club. By using the training device, a golfer may practice timing his swing to contact the ball with the club head just prior to the beginning of deceleration of the club head during the course of a typical swing. Utilization of the additional available energy may result in increased ball-driving distance. Additionally, contacting the ball while the club is in a straight position, during the transition of the direction of flex, promotes a more accurate drive.
