A key to increasing power off the tee is flexibility. Poor flexibility creates a shorter, steeper swing, which isn’t conducive to good driving.
To facilitate a better turn, try turning your left foot in towards the centre of your stance a little at address. This will free up your hips, allowing for more rotation on the backswing and creating a more powerful, and shallower, swing.
Meanwhile, when you’re practising, a great drill to get the feeling of generating more speed is to turn the club upside down and swing the grip-end as fast as you can. As there is no weight to hold you back, this gives a great feeling of releasing the club.
Combine this with a better hip position and rotation, and the speed will build naturally.
