Tips for Golf Swing
When you strain to hit the ball harder, your arms outpace your body. This prevents you from making good contact with the ball and leads to tense wrists and elbows, which decrease your swing arc and keep you from driving straight through the ball.
Visualize and practice the speed you use to toss a ball underhand about 12 yards. That should give you a rough idea of proper swing tempo. Spend a round of golf experimenting with your slower swing. Aim for about 75 percent of your maximum speed. Focus on keeping your elbows and wrists loose to achieve a wider arc, and make sure to finish with a smooth follow-through, keeping your spine vertical.
