Stand still with your arms hanging by your side.

Now fit a club into your left hand so its sits comfortably.

Extend your right hand out as if about to shake hands with someone and then place it on the handle below your left hand.

Relax your elbows and shoulders but be firm in your hands but not tight.

The tighter your grip, the more likely it is your swing will breakdown along the way if you change the pressure on the club.
