There are 5 Steps to hitting the driver further.
1. Wide stance- You want your feet to be wider than your shoulders at a minimum.
2. Shoulder tilt- tilt your spine slightly away from the golf ball so that your body can hit up on the golf ball.
3. Ball position- place the ball on a mid to high tee in the front of your stance, lining up with your front foot.
4. Width on backswing- Maximize shoulder and hip turn on the backswing to create more clubhead speed.
5. Use the ground- on the down swing you want to slightly squat into the ground. When you are about to hit the ball, use that power and momentum upwards, hitting up on the ball.
