Release the golf club drill - the simple Soloution
Perform gentle follow-throughs and stop when the club is parallel to the ground.
Take your trail hand off the club and point the palm toward the target.
Avoid an open palm (facing up) or an overly rolled palm (facing down) at the finish.
Check that your thumb is pointing straight up to the sky at the end of the release.
The feel should be identical to shaking someone's hand directly in front of you.
