Long Driving
The desired action for hitting a long drive comprises of a good; shift of weight, shoulder turn, cock of the wrists. Then a fast forward shift, strong snap of the club with the hands, good rotation of the right side around a posted left and finishing in balance on the left leg.
Much of the golf swing power comes from the flexibility of the body. Flexibility is lost by the muscles of the back being too tense. It pays then to keep in shape as every shade and in-flexion takes off or flexibility adds on to our power. Worthwhile to check-out the page on Cross Crawl exercise / fitness and coordination.
Many swings are taught to restrict the hip turn, creating tension and coil. For those players following this restricted turning of the hips you are most likely finding that your backswing is getting shorter and shorter each year. Better to take the advice of the classical players where your hips take your shoulders back. This means that where you can turn your shoulders without turning your hips, but when you turn your hips your shoulders have to turn. In long driving it is essential that your hips turn- and turn so much that your back practically faces the target when you are at the top of your back-swing.
The salient points to achieving this are with the legs and footwork.
1/ As the back-swing is underway widen the area between the legs. The right leg straightens as the right knee extends back, where the left leg flexes outward at the knee, moving across to point behind the ball. The wider the gap between the knees the greater the hip turn and the fuller you can turn the shoulders.
2/ The leg movement gains you a steady and stable platform, establishing a strong power base for the downswing. Shift your weight and use the entire downswing to generate force.
3/ Allow the right side to rotate around a posted left and finishing in balance on the left leg. Look up wood shot release.
