How to Use the Left Arm in a Golf Follow Through

A great finish in golf isn’t just for the cameras, it’s a direct result of what happened a fraction of a second earlier through impact. While many golfers obsess over the backswing, what your lead arm - the left arm for a right-handed player - does in the follow-through is a tell-tale sign of your swing’s quality. This article will break down exactly how your left arm should work after you’ve hit the ball, providing a clear roadmap to a more powerful, consistent, and balanced golf swing.

Why the Left Arm in the Follow-Through Matters

Thinking about a part of the swing that happens after the ball is gone might seem strange, but your follow-through is a direct reflection of the speed and club path you created through impact. Getting the left arm to move correctly isn’t about forcing a position, it’s about allowing a motion that completes a powerful swing. A proper left arm follow-through is where you reap the rewards of a good downswing.

Here’s what it accomplishes:

• Maximizes Power and Extension: The feeling of the left arm creating a full extension through the ball is how you transfer every ounce of generated speed into the shot. When the left arm collapses early, you're slamming on the brakes right at the critical moment.
• Controls the Clubface: The natural rotation of your left forearm and arm helps the clubface square up at impact and then continue to close post-impact. This "release" is what produces straight shots and powerful draws, preventing weak fades and slices.
• Promotes Full Body Rotation: If your arms stop, your body stops. An extending and rotating left arm encourages your chest, hips, and shoulders to continue turning through to a complete, balanced finish. It’s the final link that keeps the body’s engine running all the way.
• Maintains Your Swing Arc: Your left arm is the radius of your swing circle. A common fault is seeing this radius shorten just before or after impact (the dreaded "chicken wing"). By keeping it extended, you maintain the arc's width, leading to more consistent strikes and clubhead speed.

The Common MISTAKES Golfers Make With the a Left Arm

Before building the right habit, it’s helpful to understand the wrong ones. Watch any group of amateur golfers, and you’ll likely see these three common left arm faults in the follow-through. They are symptoms of other swing issues but manifest clearly after impact.

1. The "Chicken Wing"

This is probably the most famous fault in golf. It happens when the left elbow, instead of staying relatively close to the body and pointing down, flies out and points behind the golfer immediately after impact. The arm looks bent and disconnected, like a chicken's wing.

• What it causes: A major loss of power, as the swing's radius suddenly shortens. It also often leaves the clubface open, resulting in weak shots and slices.
• Why it happens: It’s usually a compensation. The player might be swinging a very "out-to-in" path and bends the arm to avoid pulling the ball left. Or, they might be trying to hold the clubface square through impact instead of letting it naturally release and rotate.

2. Pulling Across the Chest

Instead of the hands and left arm extending out towards the target after impact, this golfer immediately yanks the arms and club to the left and "inward." The follow-through looks short, cut-off, and low.

• What it causes: Low pulled shots, weak fades, and inconsistent contact. The player’s energy is being directed left of the target instead of at the target.
• Why it happens: This is often a result of the body stopping its rotation. When the torso stalls, the only way for the arms to keep moving is to whip around the body. It’s a sign of a disconnection between the arms and the body turn.

3. Rigidly Holding the Line

This is the opposite of the chicken wing but just as problematic. This player tries so hard to keep the left arm and clubface pointer straight at the target for as long as possible. The finish looks stiff and mechanical, with no natural rotation.

• What it causes: Pushed shots or dramatic blocks to the right. By trying *not* to release the club, the loft of the club is reduced, and the face remains open for too long.
• Why it happens: It stems from a misunderstanding of what a "release" is. Golfers who slice often think they need to prevent the club from turning over. In reality, a natural rotation of the forearms is what squares the club and produces straight shots.

Your Step-by-Step Guide to a Powerful Left Arm Follow-Through

The correct movement isn't a single position but a fluid motion that happens in sequence. Think of it less as a list of things *to do* and more as a series of checkpoints *to allow* to happen as your body unwinds.

Phase 1: Extension Towards the Target

This is the feeling immediately after impact. For a brief moment, everything should feel like it's moving together in one piece straight towards your target.

• The Feeling: As you strike the ball, imagine you're going to "shake hands" with the target. Your left arm remains long and straight, creating maximum width in your swing arc. Your right arm will now be straight as well, having taken over from the left. Your chest should be rotating open and facing where the ball was.
• Key Checkpoint: When the club shaft is parallel to the ground after impact, it should be pointing directly at your target line. Your left arm is still extended, and your hands are in front of your chest. This ensures you’ve transferred energy *outward*, not just *downward*.

Phase 2: The Natural Fold

As the momentum of the swing continues, your arms can't stay extended forever. The next move is a natural folding motion, powered by your body’s continued rotation.

• The Feeling: This is where the left arm finally begins to soften and fold. It shouldn’t be a forced bend but a passive result of your body continuing to turn through. The image of a professional’s finish is not of them holding their arm stiff, but rather allowing it to fold gracefully.
• Key Checkpoint: As your hands swing up to about shoulder height, your left elbow should start pointing down toward the ground. This is the opposite of the chicken wing. If the elbow points down, you know your arm is rotating and folding correctly in sync with your upper body.

Phase 3: The Full, Balanced Finish

The final phase is where everything settles into a poised, balanced end position. It's the sign that you’ve used all your power and stayed in control.

• The Feeling: Your body should pull your arms around to a high finish. The hands should finish somewhere above your left shoulder, near your head, with the golf club itself resting gently behind your neck or on your shoulder. The goal is to be completely balanced, with almost all your weight on your left foot.
• Key Checkpoint: Hold your finish! Try to stand there, perfectly balanced, until your ball lands. Your belt buckle and chest should be pointing at or even slightly left of the target. Your right heel should be completely off the ground. If you can hold this pose without stumbling, you’ve transferred your weight and rotated properly.

Two Drills to Groove the Right Feeling

Theory is one thing, but feeling is everything in golf. Use these two simple drills to train the correct left arm action in your follow-through.

Drill 1: The "Throw the Club" Drill

This is my favorite drill for curing the 'pulling left' or 'chicken wing' motion. It exaggerates the sensation of releasing energy down the target line.

1. Set up without a ball and make a comfortable, waist-high backswing.
2. From there, start your downswing with the thought of literally throwing the clubhead down the fairway towards your target.
3. Obviously, don't let go of the club! But this intention forces your right arm to straighten and your left arm to stay extended through impact, releasing its energy outward. You’ll feel a powerful stretch and pull through the shot. This shows you how the arm should behave when it doesn't try to steer the swing.

Drill 2: The One-Arm-Only Swing

This drill helps you feel what the left arm is supposed to do on its own and how it connects to your body's turn.

1. Take your normal stance, but grip the club with only your left hand. Put your right hand on your stomach or back.
2. Make small, slow half-swings. At first, even hitting the ball isn’t the goal. The goal is to feel the weight of the clubhead pulling your arm into a straight, extended position through the "impact zone."
3. You'll notice that to get the club through, you *have* to rotate your body. You'll feel the connection between your torso turning and your arm being pulled along. As you swing through, notice how the arm starts to fold naturally as it moves up into the finish. It’s impossible to “arm” the ball, you have to use your turn, and the arm follows.

Final Thoughts

A great-looking follow-through is also a highly effective one. The key to moving your left arm correctly is to understand it’s not an isolated action but the final piece of the body’s rotational sequence. Stop thinking about *placing* your arm in a specific position and start focusing on extending through the ball and letting your natural momentum carry you to a full, balanced finish.

Understanding these concepts is one thing, but it’s often difficult to know if you're executing them correctly. It’s hard to tell if you’re actually extending your arm or if the old "chicken wing" habit is still sneaking in. This is where Caddie AI becomes an invaluable tool.
