Improve Your Golf Swing with Single Arm Throws Drill

The single arm throws drill helps you train the release without getting overwhelmed by a full swing. By isolating each arm, you can feel how the body moves the arm, how the clubface is controlled through impact, and how the release should happen naturally instead of being forced with a last-second hand flip. This drill is especially useful if you struggle with timing, face control, or understanding what each arm is supposed to do through the strike. One version teaches the trail arm’s pushing action, while the other teaches the lead arm’s slinging action. Together, they give you a clearer picture of how the release works in your stock swing.

How the Drill Works

This drill uses a golf ball as a training tool, but you are not making a normal throwing motion. The goal is not to throw the ball like a baseball. Instead, you are using the ball to exaggerate the correct release pattern for each arm.

There are two versions:

Trail arm throw: a short, palm-driven motion that feels more like a shot put or a pressing action.
Lead arm throw: a motion that feels more like a sling or fling, with the arm and forearm rotating through.

Both are done from a short 9-to-3 motion, meaning a compact swing where your arms move back to about hip height and through to about hip height. That smaller motion makes it easier to feel the release without needing speed or a full turn.

Trail Arm Version

For a right-handed golfer, the trail arm is the right arm. In the downswing and release, this arm should work more across your body, moving in the direction of your belly button before extending out toward the strike. The key sequence is important: the elbow extends before the wrist fully releases.

That means you do not want to create power by snapping the wrist early. Instead, you want the arm to deliver the force first, with the hand and wrist responding to the momentum later. Through impact, the feeling is more like a palm press than a flick.

To create that sensation, hold a golf ball more in the center of your palm, secured by the thumb. This matters. If you hold it in your fingers like a normal throw, you will instinctively want to snap your wrist. Holding it in the palm reduces that urge and encourages the force to come from the whole arm, especially the triceps and pushing action of the trail side.

Lead Arm Version

The lead arm is the left arm for a right-handed golfer. This side works differently. Instead of a palm press, the motion feels more like a slinging release. You still hold the ball in the palm, but now you are letting the arm move through with a gentle rotational release.

The sensation is closer to letting the forearm rotate so the arm can sling outward, rather than trying to keep the forearm rigid. A useful image is that your thumb points down toward the ball as the arm moves through. That helps you avoid throwing the arm outward in a disconnected way and encourages the proper orientation of the lead arm and forearm through release.

This is not a violent roll of the forearm. It is a natural, gentle rotation that helps square and release the clubface. When done correctly, the lead arm version teaches you how the face can rotate through impact without you consciously flipping your hands.

Why the Drill Is So Effective

Many golfers try to understand release only with both hands on the club. The problem is that one arm can compensate for the other, and your body can hide the real source of the motion. By training one arm at a time, you get a much cleaner sense of what that arm is supposed to contribute.

The drill also helps you connect arm motion to body pivot. Neither arm works correctly in isolation from the body. Even in this short drill, your pivot supports the throw. The body braces, turns, and gives the arm a structure to release against. That is why the drill is not just about the hands—it teaches how the release is organized by the motion of the body.

Step-by-Step

Start with a short setup. Take your normal golf posture without a club. You are going to make a compact 9-to-3 style motion, not a full swing. Stay relaxed and athletic.
Hold the golf ball in your palm. Place the ball in the center of your palm and secure it with your thumb. Do not hold it in your fingers like a normal throwing grip.
Choose one arm at a time. Begin with either the trail arm or lead arm version. Working on one side at a time makes the sensations much easier to understand.
For the trail arm, rehearse the shot-put motion. Let the arm work inward toward your midsection as you start down, then extend the elbow through the strike area. Feel like you are pressing or palm-throwing the ball down the target line on a shallow, low trajectory.
Keep the wrist from snapping early. In the trail arm version, the power should come from the arm extending, not from a sudden flick of the hand. Let the wrist respond later to the momentum of the motion.
For the lead arm, rehearse the sling motion. Swing the lead arm through as if you are slinging the ball out toward the target. Allow a gentle forearm rotation so the release feels natural rather than rigid.
Match the motion to a small body pivot. Add a slight turn through the throw. Your body should support the release, not stay frozen while the arm works independently.
Make several short throws. Keep them small and controlled. You are not trying to throw hard. You are trying to make the motion look and feel like the release pattern you want in the swing.
Then recreate the same motion with a club. After a few throws, pick up a club and make short 9-to-3 swings. Try to match the same trail arm press or lead arm sling you just felt with the ball.
Progress to short shots. Hit little 9-to-3 shots and keep the same release feel. This is where the drill starts transferring into your actual strike.

What You Should Feel

With the trail arm version, you should feel that the arm is delivering the strike from a connected position. The arm works inward first, then extends. The sensation is not a slap or a flip. It is more of a driven press through the ball.

Key trail arm checkpoints:

The ball sits in the palm, not the fingers.
The elbow straightens before the wrist fully releases.
The hand feels like it is pressing through, not scooping upward.
The motion stays compact and low through the strike area.

With the lead arm version, you should feel the arm swinging through with a free but controlled release. There is some natural forearm rotation, but it is not an aggressive roll. The motion should feel smooth and connected to the pivot.

Key lead arm checkpoints:

The throw feels like a sling, not a shove.
The forearm rotates gently through release.
The arm stays connected to your body motion.
The release feels like it happens through the swing, not before it.

In both versions, you should notice that the body helps organize the release. Even though you are isolating one arm, the arm should not feel like it is acting alone. Your pivot provides the structure, while the arm supplies its specific release pattern.

If you then pick up the club and make a short swing, the release should feel more intuitive. The trail arm may feel like it is driving and extending, while the lead arm feels like it is slinging and rotating through. Those are the same release ingredients you use in a full swing, just in a smaller and easier-to-learn format.

Common Mistakes to Avoid

Holding the ball in your fingers. This usually creates too much wrist snap and turns the drill into a generic throwing motion instead of a golf release drill.
Throwing too hard. Speed is not the goal. If you throw aggressively, you will usually lose the structure of the motion.
Snapping the trail wrist early. The trail arm should extend first. An early flick tends to add loft, poor face control, and inconsistent contact.
Keeping the lead arm too rigid. The lead arm version needs some natural rotation. If you lock it up, the release becomes artificial.
Rolling the lead forearm excessively. You want a gentle release, not a dramatic rollover that would shut the face too quickly.
Using only the arm with no body support. Even in a single-arm drill, your body should pivot and brace the motion.
Making the motion too long. This drill works best in a 9-to-3 format. A bigger swing often adds unnecessary timing issues.
Trying to copy positions instead of creating the right throw. Focus on the motion and force pattern, not on freezing yourself into a picture.

How This Fits Your Swing

The single arm throws drill fits into a much bigger concept: the release is not just a hand action. It is the result of how your body, arms, and club work together through impact.

The trail arm helps you understand how force is delivered into the strike. It teaches you that the club is not released by a random wrist throw. Instead, the trail side works from a connected position, extends through, and allows the club’s momentum to finish the release.

The lead arm teaches the other half of the equation. It shows you how the clubface can rotate and release through impact without needing a conscious flip. That is a huge piece of controlling the clubface. Many golfers either hold the face open too long or try to save the shot with their hands at the last moment. This drill helps replace both of those patterns with a more natural release.

It also reinforces the idea that the body swings the arm. Even though you are training one arm at a time, the motion still depends on the body’s pivot and bracing action. In a good swing, the arms are not disconnected throwers. They are being delivered by the motion of the body, then releasing in response to that motion.

That is why this drill transfers so well into short 9-to-3 shots. Those mini-swings strip away complexity and let you blend the arm action with the pivot. Once that starts to feel natural, you can gradually let it show up in longer swings.

If you tend to get stuck, flip at the ball, hold the face open, or simply feel confused about what the release should be, this drill gives you a simple and athletic way to learn it. Train the trail arm press. Train the lead arm sling. Then bring those feels into your short swings, where the release becomes easier to own and repeat.
