Same Goal, Different Paths
Whether you are best suited to use a one-plane swing or a two-plane swing, your goal is the same - to return the club shaft to the same position you held at address with speed and consistency. Keeping the head still is only one important aspect of consistency, as we discussed in Step Nine.
One-Plane
If you have strong chest and shoulders and flexibility in your torso, you may be a good candidate for the one-plane swing. In this swing, you keep your arms moving around the body on the same plane they create at address. It typically involves a significant bend in the right elbow.
