What Does Lag Feel Like
What does "Lag" feel like?
Simply take a piece of rope and hold it like a club.
Go the top of the swing and allow the rope to rest on the top of your right shoulder. As you start down, you will "feel" like the rope stays on the shoulder as you take your hands directly downward to the ball, or at the "aiming point." The "end" of the rope is "lagging" my hands.
A properly lagging clubhead produces a strong downward thrust, which adds distance, trajectory and consistency.
The majority of golfers do just the opposite. They try moving the clubhead with the wrists.
This produces a "quitting" motion and the club moves upward toward impact instead of downward. Practice these two drills and what your game improve.
