Rotary Golf Swing - Takeaway Chin Line


Published: May 24, 2025

We've talked about the takeaway a lot on the website, and we have a video about working the arms up and back behind you, and getting some flow to get the golf swing started.

However, we still see a lot of golfers struggling with the takeaway position, often with a tendency to get the club too far inside and the hands outside.

We like to say, "Hands inside, club head outside," but what does that mean, exactly? A lot of people seem to find it confusing, so that's what we're going to look at today.

We'll start with a look at Chuck's setup position, and a line drawn straight down from his chin.

In a good Rotary Swing setup, your arms hang more or less directly below your shoulders. Of course there's a slight angle to them, but with a midiron they shouldn't stick out past the chin line.

That will change with the driver and the longer clubs. The arms will get out a lot farther as the lie angle decreases and the club shafts get longer, but they should definitely be inside that chin line with the midiron — Chuck has a 6 iron in these photos.

The Arms Never Break That Line

We're looking at the takeaway mechanics, so of course the next important piece is how the club works back from here.

The arms should never break the chin line. This is really important.

The perfect angleThe perfect angle

Taking Chuck's swing back to where the club is parallel to the ground (it looks like it's below parallel, but that's just the camera angle) we see that the arms never break that plane. Even the lead arm stays inside the chin line.

This creates the perfect takeaway angle. As the lead arm works back it's angled away from that plane line, in toward the ball of the trail foot. This is ideal.

This is a simple takeaway, driven by the body, the core rotation, and everything turning back in sync. The arms and hands are not doing anything too aggressive. Of course, passive arms doesn't mean that they just hang limp.

The arms do have to swing up and around, and the club has to set. All those things have to happen, but we don't want to overdo any of that and have it end up as the star of the show. This is exactly the kind of swing fundamentals that elite players master — and that our AI swing analyzer evaluates in your own technique.

Coming into impactBack on the chin line coming into impact

If you rotate correctly, you should find your arms working right back on that line and never getting outside of it.

The same is true as you come down. You get right back on that line and come down into impact position.

The main thing is that if the takeaway starts out correctly, you have a good chance of getting the rest of the swing to work correctly.

When you watch your swing on video, draw that line straight down from your chin and make sure your arm never gets beyond that line. That's important for building a consistent golf swing.

Look at a Student Example

We see a lot of students whose lead arms do go well outside that line. We'll take a look at one student's swing here, so you can see what we're talking about and watch for it in your own golf swing analysis.

We'll draw the same red line on this golfer's setup. The first thing you can see is that the hands are already outside of that line, before the swing even starts.

This will create a tendency for the arms to want to swing very flat. When that happens, of course the club head path will go to the inside while the hands go to the outside.

As the club works back we see that the lead arm works well outside of the chin line very early in the swing.

When the arm works out away from the body instead of in around it like that, the club head is forced inside. The golfer is not able to get the club up on plane.

As the arm works outside the line, the club head gets way to the inside. By the time the club is parallel to the ground the club head is way behind the body. This is a very common takeaway mistake and it starts at setup.

The arms are angled out too far at setup. Ideally he would be tilted over a bit more, but he's close enough. If he just gets his arms hanging down then he'll be able to stay inside that line and maintain a much better swing plane.

Check Your Own Swing

When the hands go outside the chin line, the club head is going to go inside, and you want just the opposite.

You want the hands inside the chin line and the club head more outside.

That's the combination you're looking for, and this is the mistake to avoid. The best way to work on this is to take some video and go ahead and draw that line straight down from your chin. See if your arm is breaking that line at setup, and through takeaway. You can also use our AI swing analyzer to get instant feedback on your takeaway path and arm position.

If so, fix it and you'll have a much better takeaway, which will give you a much more consistent ball striking pattern and a much better chance at making solid contact, each and every swing. Pairing this awareness with structured repetition through the GOAT Drill system is one of the most effective ways to engrain the correct takeaway mechanics into muscle memory.

Checkpoints for Practice

  • You always want your "hands inside, club head outside" in the takeaway
  • Watch your swing on video and draw a line straight down from your chin at address
  • With a midiron, your hands should be inside that line at address, and stay there throughout the swing plane
  • When the club is parallel to the ground, the lead arm should be angled in toward the ball of the trail foot
  • Keep your hands inside the chin line for more solid contact and a more consistent swing, every time

How to Master the Rotary Golf Swing Takeaway

Learn to maintain proper arm positioning during your golf swing takeaway for better consistency.

  1. 1

    Set Up Correctly

    Begin by positioning yourself with your arms hanging directly below your shoulders. Ensure that your arms do not extend beyond the chin line, especially when using a midiron.

  2. 2

    Maintain the Chin Line

    As you initiate your takeaway, focus on keeping your arms inside the chin line. This is crucial for establishing the correct swing path and ensuring your arms do not break this plane.

  3. 3

    Create the Perfect Angle

    As you take the club back, ensure that your lead arm remains inside the chin line. This will help create the ideal takeaway angle and maintain a consistent swing.

  4. 4

    Use Core Rotation

    Drive your takeaway with your body and core rotation rather than your arms. This will help keep your arms passive and prevent over-aggression in your swing.

  5. 5

    Check Your Swing Path

    After your takeaway, ensure that as you come down into impact, your arms return to the chin line. This consistency will help improve your overall swing mechanics.

  6. 6

    Analyze Your Technique

    Record your swing and draw a line from your chin to check if your arms stay inside this line throughout the swing. Adjust your setup if necessary to maintain this alignment.

Frequently Asked Questions

What is the importance of the chin line in the golf takeaway?

The chin line is crucial for establishing the correct takeaway position in your golf swing. It serves as a reference point to ensure that your arms remain inside this line during the takeaway. This alignment helps maintain the proper swing path, which is essential for achieving a consistent and effective golf swing.

How can I ensure my arms stay within the chin line during my swing?

To keep your arms within the chin line, focus on your setup position and ensure your arms hang directly below your shoulders. As you initiate your takeaway, concentrate on rotating your body and allowing your lead arm to move inward toward your trail foot, rather than extending outward. This will help maintain the correct angle and improve your swing mechanics.

What happens if my arms go outside the chin line during the takeaway?

If your arms move outside the chin line during the takeaway, it can lead to a flat swing path and an incorrect club head position. This misalignment often results in the club head moving too far inside, making it difficult to achieve the proper swing plane. Correcting this issue is vital for building a reliable and consistent golf swing.

When should I check my chin line during my golf swing?

You should check your chin line at both the setup position and during the takeaway. Drawing an imaginary line down from your chin can help you visualize the correct arm position. Additionally, reviewing your swing on video can provide valuable feedback on whether your arms remain inside this line throughout your swing, helping to reinforce good habits.
