When you're taking your practice swings on the tee, swing the clubhead several inches off the ground. This encourages you to swing more around your body (rather than up and down), which will help increase your clubhead speed and add distance. And when you're at the range, spend more time with your driver and woods than the rest of the long clubs in your bag. You'll be hitting these clubs more frequently than your 5- or 6-iron, so give them a good workout.
