Why do I hit fat golf shots?
The short answer
A fat or heavy iron shot happens when the club contacts the ground too far behind the ball, interfering with the strike. For a normal iron shot from turf, the useful task is ball-first contact followed by ground contact. The heavy strike identifies a contact problem, but not one unique swing fault.
What to check first
01
Find the first ground contact
On a permitted grass practice area, use a simple visual reference for the ball position and note where the club first disturbs the turf. A mat can disguise ground-first contact by allowing the club to slide or bounce into the ball. Sound and ball flight alone may mislead.
02
Compare the lie and the club
Separate a flat-lie wedge shot from a long iron out of thick rough. Ball position, slope and turf change the task. Group similar shots before concluding that all your heavy strikes share the same cause.
03
Review movement without inventing pressure data
A face-on video can show visible lateral and vertical movement, while down-the-line can show changes in posture. Neither view directly measures pressure under your feet. A heavy shot does not prove that all your weight stayed on the trail side.
04
Check the intention
If you are trying to lift the ball, test whether a shorter motion aimed at a predictable ground-contact point helps. Let the club's loft do its job. Do not replace the lifting thought with an uncontrolled effort to dig deeply into the turf.
Try this in practice
With a short iron, make small rehearsal swings and brush the turf on the target side of a marked ball position. Add a ball and hit five comfortable shots. Increase swing length only when the strike becomes repeatable. Use the practice facility's permitted marking method.
What to measure
Record ground-first versus ball-first contact and the carry pattern for each small group. A deeper divot is not the goal. Look for dependable contact that survives a change of target.
Keep the conclusion proportionate
This check concerns ordinary iron shots from turf. Bunker shots and some specialist short-game shots intentionally use different ground-contact patterns. Persistent contact problems deserve a review of the whole movement, not a forced weight-shift prescription.
