When good players hit the ball, their swing looks effortless, and the ball goes a long way. How do they do that? The Lever System is the secret and magic to generating a lot of speed and force with your driver. It is important to create 90-degree angles on the backswing, holding the angle on the downswing and letting the arms unhinge into the ball.
On the follow-through, your arms have straightened out, and then the club rehinges because your body stops rotating. You need to learn how to swing the driver back and forth fluidly because your hands have to react to the momentum of the club.
Learning to use the Lever System correctly is the first and most crucial aspect of driver consistency and getting maximum speed.
