PGA Professional Mark Crossfield demonstrates a lead-hand-only practice drill designed to fix an over-the-top downswing path. By isolating the left hand, golfers learn to shallow the club behind their body and allow the clubhead to release properly through impact rather than pulling across the target line.
Isolate your lead hand while teeing up a 7-iron shot, keeping your trailing hand behind your back.
Feel the club drop behind your body during the downswing transition rather than steepening over your hands.
Allow the clubhead to rotate past the handle around waist height instead of pulling the handle low and left.
Alternate hitting two lead-handed drill shots followed by one normal swing to translate the drill feel to your regular swing.
