Fat iron shots occur when the club contacts turf before the ball or when your low point moves too far behind the ball. Fix setup (ball slightly forward of center for mid/short irons, weight slightly on lead foot), maintain spine angle through impact, and feel forward shaft lean so hands lead the clubhead at contact. Focus on shifting weight to your front foot through the shot, keeping your lower body engaged so the bottom of the swing arc is after the ball. Use drills that build a consistent impact position and shallow low point — practice deliberately taking a small divot after the ball and feel the club compress the ball before any turf. Slow the tempo to improve sequencing and make controlled swings that emphasize balance and follow-through.
Common causes
Weight staying back so low point falls behind the ball
Early extension or rising up, moving low point back
Hands trailing at impact (lack of forward shaft lean)
Practice ideas
Impact bag: make controlled strikes to feel hands leading and club compressing the bag
Divot/coin drill: place a coin just past the ball; aim to hit ball then take a divot that begins after the coin
Step-through drill: after impact step the trail foot through to force weight onto lead side and a forward impact
