Key Takeaways
- Overswinging” usually refers to the club going past horizontal or the arms moving beyond a structurally stable position.
- A longer swing is not automatically bad — it only becomes an issue if it causes loss of control, sequencing problems, or inconsistent ball-striking.
- Many golfers overswing due to excess arm lift, collapsing elbows, or insufficient body rotation.
- The correct backswing length is unique to each golfer, influenced by flexibility, coordination, and strength.
- What matters most is whether your swing length allows you to deliver the club on time and return to impact with structure.
- Sue outlines the key signs that your backswing length is functional — and what red flags indicate it’s hurting your performance.
