Swing Speed vs. Ball Speed | Golfweek

To add to the distance of their golf shots, many golfers focus their efforts on increasing the speed of the ball by increasing the speed of their swing. While there is a correlation between swing speed and ball speed, adding swing speed alone does not guarantee longer shots. Just as important is the ability of the golfer to maximize swing efficiency and to develop the ability to control the tempo of the swing. It is
