What Is Lag in Golf?

By Spencer Lanoue

Effortless power in the golf swing often starts with one word: lag. You’ve likely heard it mentioned by commentators and golf coaches, usually when describing the beautiful, powerful moves of tour professionals. This article will break down what lag actually is, why it's so important for distance and solid contact, and most importantly, how you can start training it into your own swing with simple, effective drills.

So, What Exactly Is Lag? A Simple Definition

Forget the complicated physics for a moment and think about snapping a towel. Where does the speed come from? It’s not from how fast you move your hand, it’s from the whip-like action at the very end of the towel. The tip of the towel "lags" behind your hand, and when it finally catches up, it does so with incredible speed. That, in a nutshell, is the principle of lag in a golf swing.

Technically speaking, lag is the angle created between your lead arm (left arm for a right-handed golfer) and the golf club shaft during the downswing.

At the top of your backswing, your wrists will have naturally hinged, creating roughly a 90-degree angle between your arm and the club. Tbe goal is to maintain or even slightly increase this angle for as long as possible as you start the downswing. The clubhead "lags" behind your hands, storing up potential energy like a drawn-back catapult. This energy is then unleashed at the perfect moment - right at the bottom of the swing, through impact - creating maximum clubhead speed exactly where you need it.

Players who lack lag do the opposite. They release this angle too early from the top of the swing, a move called "casting." This action drains all the stored energy long before the club gets to the ball, forcing the golfer to try and generate power with their hands and arms alone, which is weak and inconsistent.

Why Lag is a Game-Changer for Your Swing (Hint: It’s Not Just for Pros)

Creating lag isn't just a fancy move to look like a professional, it has some very real benefits that can transform your game, no matter your handicap. Understanding these benefits will motivate you to practice the right feelings and moves.

1. Effortless Power and More Distance

This is the big one. Lag is the ultimate speed multiplier. By maintaining that angle, you allow the momentum built by your body's rotation to transfer into the clubhead at the last possible moment. A swing with good lag actually feels slower and more composed from the top. You aren't "hitting" from the top, you're simply turning your body and letting the clubhead catch up. The result? Surprising speed and distance without feeling like you're trying to swing out of your shoes. You’re letting the design of the golf club and the principles of physics do the heavy lifting.

2. Crisper, More Compressed Ball Striking

Have you ever watched a pro take a divot and marveled at how it’s always after the ball? That’s lag at work. When your hands lead the clubhead into the ball, the club is still traveling on a slight downward path at a a good angle of attack. This allows you to strike the ball first, then the turf. This "ball-then-turf" contact is what produces that incredibly satisfying, compressed feeling and a penetrating ball flight. Without lag, when the clubhead passes the hands too early, the bottom of your swing arc also moves too far back. This leads to common mishits like catching the ball "thin" (hitting the equator of the ball) or "fat" (hitting the ground before the ball).

3. Improved Consistency and Accuracy

A golf swing that relies on perfectly timing an early release of the hands is incredibly difficult to repeat under pressure. There are just too many variables. When you use your body's rotation as the engine and let lag sequence the swing naturally, the large muscles take over. The sequence becomes: hips, torso, arms, then club. This is a much more repeatable motion than timing with your quick-twitch hand and wrist muscles. With a more stable, body-driven sequence, you’ll not only hit the ball more consistently, but your shots will also be more accurate because the club face is more stable through impact.

The Common Mistakes That Kill Lag Before It Starts

Most amateur golfers lose their lag right at the beginning of the downswing. The instinct to "hit" the ball is strong, but it's this very instinct that causes the most problems. Understanding these common faults is the first step to fixing them.

Casting From Fhe Top

This is lag's number one enemy. "Casting" is when you actively unhinge your wrists from the top of the backswing, pushing the clubhead away from your body as if you were casting a fishing line. It's often caused by an anxious subconscious desire to help the ball get airborne or to generate speed. What it actually does is throw all your stored power away, forcing you to try and manufacture speed just before impact. It’s an "early release" of a powert hat needs to happen much later in the swing a ta crucial part.

Poor Body Sequence: An "Armsy" Swing

A proper downswing starts from the ground up. The left hip shifts slightly toward the target, and then the hips begin to unwind, followed by the torso and shoulders. This movement pulls the arms and club down. When this sequence is reversed, and the initial move is with the hands and arms, you will have to cast the club to get it back onto a proper path. This is also the root cause of the dreaded "over-the-top" swing path which results in slices and pulls.

Too Much Tension in the Grip and Wrists

Lag requires your wrists to be soft and free enough to hinge and unhinge naturally. Players often grip the club way too tightly, especially at the transition from backswing to downswing. This "death grip" prevents the wrists from acting as the freewheeling hinges they are designed to be. A tense grip leads to tense forearms, which locks up the entire mechanism, forcing an early release of the little angles you managed to create.

Your Step-by-Step Guide to Creating More Lag

Now for the fun part: teaching your body how to do it. These aren’t overnight fixes, but with consistent practice, you can ingrain the feeling of a properly sequenced, lag-filled golf swing.

Fundamental First: Soft Hands

Before any drill, check your grip pressure. On a scale of 1 to 10, where 10 is gripping as hard as you can, you should be a 3 or 4. You need to hold on securely, but your wrists and forearms must feel relaxed and supple. Think of holding a small bird - firm enough so it can't fly away, but gentle enough not to harm it.

Drill 1: The L-to-L Drill

This is a classic drill for teaching both wrist hinge and sequencing. It's fantastic for isolatingparts of the swing in bite-sized chunks to feel how the club should move.

  • Take a 7- or 8-iron and get into your normal setup.
  • Swing back until your lead arm is parallel to the ground. Your club shaft should be pointing to the sky, forming a perfect "L" shape with your arm. This is a perfect 90 degree wrist set.
  • Now, initiate the downswing by bumping your left hip toward the target. Your only thought should be to maintain that "L" shape for as long as you can manage as your body rotates.
  • Let your body's rotation carry the club through the impact area.
  • Continue swinging through until your right arm is parallel with the ground and the club points to the sky again, forming a reverse "L" on the other side.
  • Start with small, slow swings and gradually increase the speed as you get comfortable with the motion. Focus on the feeling of your hands leading the clubhead through the ball.

Drill 2: The Pump Drill

This drill is exceptional for helping you feel the "ground-up" sequence and for stopping you from casting the club from the top of your swing a t maximum speeds everytime so you'll feel more in control.

  • Take your normal backswing to the top.
  • From the top, start your downswing - letting the hips lead - and bring the club down until your hands are about belt-high. Then stop.
  • Without pausing, swing the club back up to the top.
  • Do this little rehearsal "pump" down and up two or three times. Feel how your lower body initiates the move and your wrists stay passively hinged.
  • On the final pump, continue the motion all the way through the ball and hit the shot.

Drill 3: The Right Hand Only Swing

For right-handed players, swinging an iron with only your right hand is an amazing way to feel how the club is naturally supposed to release and lag without conscious thought from you.

  • Grip down significantly on a short iron with just your right hand.
  • Make some slow, smooth half-swings.
  • You'll notice that you cannot force or cast the club with just one hand, you have to let your body rotation create momentum. It will feel much easier to keep the club head trailing behind your hand.
  • After a few practice swings, try to hit a few balls. You'll be amazed at how this forces you into a great sequence where your hand leads the club through impact.

Final Thoughts

In the end, lag is less about force and more about timing, sequence, and creating a whip-like release of energy. By focusing on proper sequencing starting from the ground up, keeping your grip pressure light, and practicing the right drills, you can transform your swing from an inefficient "hitting" motion to a powerful, fluid, and repeatable swinging motion.
