A good stance is of great importance to a good golf swing. You are making an athletic motion when you swing a golf club, so it is vital that you are in an athletic position, ready to swing the club to the best of your ability.
Stand tall with your heels about shoulder width apart. Bend slightly from the top of your hips, keeping your back straight and letting your rear stick out. Let your arms hang down, gorilla style. Don't let your chin tuck into your chest. Look at the ball with the bottom of your eyes as much as possible. Let your right side (for right-handed golfers) tilt slightly lower than the left. Keep your weight equal and slightly toward the forward part of both feet.
Now relax the knees slightly. This is key…Make sure that when you relax the knees you keep your rear sticking out. Avoid that sitting down position that makes it hard to shift your weight properly. A proper stance and posture means the right position for the most effective golf swing. Practice the proper stance in front of a mirror and memorize its feel.
“Balance”
Your weight should be balanced on the balls of the feet, not on the heels or toes. With short irons, your weight should be 60-percent on the target side foot (left foot for right-handers). For middle iron shots the weight should be 50/50 or equal on each foot. For your longest clubs, place 60% of your weight on the backside foot (right foot for right-handers). This will help you swing the club on the correct angle on the back swing.
