Two-Plane Swing
A two-plane swing lifts the arms onto a steeper plane than the shoulders set at address. The backswing looks taller, with more arm-body separation.
The two-plane swing describes a style where the arms swing on a noticeably steeper plane than the shoulder-turn plane established at address. This is most visible at the top of the backswing. There, the hands are higher and the arm plane looks more vertical relative to the body's rotation. This style is often associated with a more upright setup posture and a greater sense of separation between the arms and torso.
A well-executed two-plane swing requires the downswing to shallow the arm plane back down, closer to the shoulder plane. That is how it delivers the club on a good path. This transition move is exactly why "shallowing" and "the slot" receive so much coaching attention for players with a steeper backswing plane. Golfers who don't shallow adequately from a two-plane backswing are especially prone to over-the-top patterns.
As with the one-plane swing, two-plane mechanics appear throughout the highest levels of pro golf. For an individual golfer, the relevant question is not which style is theoretically superior. It is which one they can repeat reliably, session after session, under pressure.
Example
A golfer with a taller, more upright setup lifts the arms noticeably higher than the shoulder turn at the top of the backswing, then relies on a shallowing move in transition to deliver the club on plane.
Common mistakes
- Adopting a steep two-plane backswing without developing the shallowing move the transition requires, which is a common root cause of an over-the-top pattern.
In SwingVantage Motion Lab
Motion Lab does not sort swings into one-plane or two-plane styles. On a down-the-line clip, you can tap the clubhead on a few frames going back and coming down. It then fits both planes and can note a downswing shallower or steeper than the way back. Without marks, it shows only your hand path against a reference line.

- One-Plane SwingA one-plane swing keeps the arms near the tilted plane the shoulders set at address. The backswing looks flatter, and the trail arm folds close to the chest.
- Swing PlaneSwing plane is the tilted circle the club travels on around your body. A consistent plane makes it easier to return the club squarely and on path at impact.
- Personal Swing SignatureA personal swing signature is a golfer's stable tempo, plane, and sequencing pattern. It separates a truly "different" swing from a temporarily flawed one.
