Why This Drill Works (Kinetic Mechanics)
Placing the lead thumb against the trail palm's lifeline creates a direct tactile pressure point. Pushing against that point in the downswing while keeping the trail elbow tucked forces lead forearm supination, squaring the face and curing weak slice contact.
How to Perform the Drill
The coach gives no set rep count. Our general guideline: 3 sets of 10 slow rehearsal reps, then half swings with a ball, adding speed only once the steps feel natural.
Setup: Create a 'butterfly' hand connection by placing your lead thumb against the lifeline and heel pad of your trail hand.
The Feel: During a short half-swing (about 80 yards with a 7-iron), ensure your trail elbow stays tucked under the lead side.
Execution: As you swing down, feel your trail arm push against the pressure point on your lead thumb.
Result: This motion forces proper lead forearm supination (turning over), squaring the clubface naturally through impact to produce a solid push-draw.
