What Early Extension Looks Like
From a face-on camera angle, early extension is easy to spot: as the downswing begins, the trail hip thrusts forward (toward the ball) rather than rotating open (away from the ball). Simultaneously, the golfer rises out of their address posture. The telltale signs: a rounded lower back at impact, club path that goes over the top (outside-in), and consistent distance inconsistency.
The Most Common Causes
Early extension has three primary root causes: (1) insufficient hip mobility preventing a proper hip turn so the body compensates with a thrust, (2) poor hip stability (weak glutes) that cannot support rotation without thrusting, and (3) a swing path that is too steep, forcing a last-moment compensation. Identifying which is your primary cause determines the most effective fix.
The Chair Drill
Set up to a golf ball with a chair directly behind you (touching your trail glute). Make slow-motion swings feeling the trail glute stay in contact with the chair through the downswing. When early extension occurs, the hips thrust forward and the trail glute lifts off. Keeping contact forces proper hip rotation.
Hip Mobility Fix
If tight hips are the cause, the solution is not a swing fix — it is a hip mobility fix. Three months of consistent hip flexor and hip internal rotation stretching (see our fitness guides) can resolve early extension that years of swing tips could not, because the root cause was always physical restriction rather than swing mechanics.
Posture and Setup Check
Early extension is also associated with excessive knee flex at address (which restricts hip rotation) or too upright a spine angle (which leaves no room for the club to pass). Set up with more hip hinge, less knee bend, and allow your weight to be distributed through the balls of your feet. This creates the structural conditions where rotation is more natural than thrusting.
Key Takeaways
- Record your swing face-on to confirm early extension is actually present before working on it
- Hip mobility work often fixes early extension faster than any swing tip
- The chair drill is the highest-impact drill for this fault
