There is a skill development process to max out your driver and get the best distance.
The first part of this process is your grip and the lever system. Start swinging your driver back and forth with your left hand. Notice the lever created with your left hand, the club on the backswing, and the follow-through. This motion is the L to L.
Your arm should be relaxed going through this motion. Your body nudges and starts your left arm, but your left arm takes off, and your chest goes with your arm. The same levers work with your right hand.
The whole motion is soft; if you combine that and add speed, you have something. If your wrists are tight and you add too much body and swing hard without the lever system, you won’t create as much speed as you can.
One of the first drills you can do is Sitting on a Chair Drill or sitting on your knees and making swings with your driver. Start making easy swings, trying to hit tees, and then move to balls.
Sitting on your knees helps you focus on the lever system and keeps your legs out of play. You will be surprised how far you hit the ball with an easy swing. You will also realize how little effort goes into it.
Once you train the lever system and as your body starts to move faster and faster, then you can potentially create more speed.
