Increasing swing speed can be a vital part of any golfer's improvement. After the basics of the swing have been learned, golfers want to continue to climb the ladder and gain more distance. One way to do so is to increase swing speed with proper technique, not by swinging harder. Greater club head speed at impact translates into longer shots.
Increase core strength and flexibility so your body can coil properly. Sit on an exercise ball and find your balance point. Hold a lightweight dumbbell in each hand and do 10 curls with each arm. Alternate right-hand curls with left-hand curls; take a 30-second break and do 10 more.
Use a weighted club to build strength in your wrists and shoulders. Swing the weighted club for one minute, and then take a 30-second break. Swing the club for another minute, followed by another break.
Relax the muscles in your shoulders and arms. Muscle tension slows the clubhead speed.
Hold the club with a minimal amount of grip pressure. If you hold the club tightly, you prevent the club from releasing. That release is necessary for optimal clubhead speed.
Lengthen your swing arc by extending your club back along the target line. Don't be in a hurry to pick the club up.
Turn your driver upside down and hold it near the head with the grip pointing toward the ground. Swing the club and try to make it swoosh at the bottom of the swing. Keep swinging until you notice a higher pitched swoosh. That's an indication of increased swing speed.
