from the series "how it feels to me"
The left shoulder goes down and rotates under the chin while the rest of the body coils in. The hands should stay relatively connected with the overall turn and downward motion of the left shoulder. Maintaining the original arms to shaft angle during the initial turn is important for keeping the hands on plane, lower than most people realize. The feeling creates a connection between the shoulders and hips for the initial start of the swing that is gradually over taken by the shoulder turn. Maintaining proper posture will have the affect of the left arm coming in close to the chest. By keeping the elbows closer to each other creates a relatively tighter swing, better for both power and control.
The hands should begin extending and become activated, picking the club up when they reach the right leg. Because the upper torso is rotating in correlation with the hips, the hands will be lower and on plane. The dynamics of this motion creates a certain amount of hip rotation. The amount of hip rotation and its relation to the axis point determines the amount the right leg straightens at the top of the swing. If the weight moves to the right or away from the target the right leg remains more flexed and stable. If the weight moves left, essentially tilting toward the target, the right leg straightens more to some degree. This left leaning position at the top of the swing also adds stability. This movement is balanced and centered. The weight and force from your chest and arms creates a force that is countered by a leftward motion as the backswing reaches the top. A reaction to remain balanced realizing your back is to the target.
Like trying to close gaps within the fingers of the
grip, the golf swing is often about finding parts of the body that are
moving or bending that do not need to move or bend.
