Fat shot - The cure

Recently, I went into a slump where I kept hitting fat shots. I finally realized that it was my posture that's causing all the problem. I had most of my weight on the toe.

When all of your weight is on the toe, your body will tend to dip down during the down swing. Thus, causing the club head to swing lower and hit behind the ball. The cure is simple. It's to make sure you have good balance on your feet. Not on the toe nor the heel. In contrast, if most of your weight is on the heel, it usually cause the club head to swing higher as the body raises during the down swing. This can also be explained as lose balance during the swing.

In short, a posture with good balance is essential to hit the ball more consistently.
