Make the first small move as if you're about to sit on a tall chair.
Your feet should be shoulder width apart to make it easy to shift your weight.
To make sure you have the right posture follow this routine:
Grip the club then raise it until it is parallel to the ground and you are standing upright
Lower the club head to the ground by bending forward from the hips. Stop when the club head touches the grass
Flex the knees just enough to create tension in the thighs.
Do not bend your knees too far - you should be able to flex them without reducing your height.
You are now ready to make your first swing.
