Hip Sway vs Hip Turn: Why Sliding Kills Your Coil
5 min read · by the AnchorStance team
In a good backswing the hips rotate; in a common bad one they slide. Hip sway is lateral drift away from the target during the backswing, and it quietly costs you twice: the coil between hips and shoulders never loads, and the downswing has to find its way back to the ball from somewhere the swing never planned to be.
Sway, measured
From a face-on video, sway is how far your pelvis moves along the target line during the backswing relative to where it started. AnchorStance reports it as a normalized drift with an ideal band near zero — a little movement is human; a slide is a fault.
The tell-tale pair: high hip sway with a low X-factor. The hips that slide are the hips that did not turn.
Turning instead of sliding
The fix is a feel change plus a constraint:
- Feel: turn your trail hip behind you — like closing a door — instead of pushing it away from the target.
- Chair hip-turn drill: address with your trail hip lightly touching a chair back beside you; turn to the top keeping the same light contact. Pressure into the chair = slide.
- Trail-hip wall check: same idea against a wall at the range.
What improves when sway goes
Players who replace slide with turn typically see X-factor rise, strike location stabilize, and the transition stop feeling rushed — the downswing starts from a loaded place instead of a stranded one. Watch all three numbers move together on your metric trends.
