Swing shallow for longer drives

With the driver in your hands, the swing plane needs to be shallow in order to deliver the club on the correct path and the correct angle of attack. As TG Elite Pro Gareth Johnston explains here, a steep plane with the driver encourages a glancing blow, which saps power and accuracy from your shots.
  
A great way naturally flatten out your swing plane is to swing the club back with the left hand only. The weight of the clubhead should cause the shaft to point at the ball, an ideal position for the club to be in halfway back.
