The right stance not only allows for proper alignment, but also for a balanced swing, prepared usage of the proper muscles, and the maximum strength and control over your swing. We align our body to the target only after we have aligned the club head to the target. A proper stance starts with your feet being aligned at the target, followed by your knees, hips and shoulders. Your feet should be shoulder width apart, your front foot should be slightly opened towards the target and your back foot should be perpendicular to the target. As you increase in club, your stance should widen for further stability. Your shoulders will be naturally open to the target line because your arms are not at equal length while holding the club. Make sure to close your shoulders slightly to stay aligned with the target line. The proper stance affects how controlled the backswing is, governs the amount of hip turn in the backswing, and allows for the hips to clear through the downswing. Your front arm should be extended at all times to allow the club to travel in its maximum arc. "The elbows should be tucked in, not stuck out from the body. At address, the left elbow should point directly at the left hipbone and the right elbow should point directly at the right hipbone. Furthermore, there should be a sense of fixed jointness between the two forearms and the wrists, and it should be maintained throughout the swing." "You should bend your knees from the thighs down. As your knees bend, the upper part of the trunk remains normally erect, just as it does when you sit down in a chair. In golf, the sit-down motion is more like lowering yourself onto a spectator-sports-stick. Think of the seat of the stick as being about two inches or so below your buttocks."
