If you've ever been told to “rotate more” in your golf swing, there's a pretty important question that usually gets left unanswered:

What exactly are you supposed to rotate — and what should your arms be doing while it happens?

A golf swing looks like one big circular motion, but when you break it apart, the movements are actually much simpler.

Your arms have a job. Your lower body has a job. And those movements have to come together in the right place at impact.

Here's the simple version:

ARMS: Up → Down
BODY: Turn → Turn Through
IMPACT: The movements come together
SPEED: Add it once the movement is repeatable

Let's break down each piece.

How to Rotate in the Golf Swing

Before worrying about how many degrees your hips should turn or trying to copy somebody else's swing, it helps to understand what you're actually trying to accomplish.

I like working backward.

Instead of starting at address and trying to build a perfect-looking golf swing from there, first figure out:

Where do I want to be when I hit the golf ball?

That's your impact position.

Once you know where you're trying to arrive, the movements of your arms and body become much easier to understand.

But first, we need to separate them.

What Should Your Arms Do in the Golf Swing?

There's a concept you may have seen online called the Arm Swing Illusion.

The idea is that your arms aren't actually swinging around your body the way they appear to when you watch a golf swing.

And I agree with it.

If I stood still and simply swung my arms around myself, I'd be making a big side-to-side movement. That's not what's actually happening.

The movement of the arms themselves is much more up and down. Your body's rotation is what makes that movement appear to travel around you.

You can test this without hitting a golf ball.

Take your normal address position and start your backswing until the club reaches what you'd consider a good takeaway position. Stop.

Now return your shoulders so your chest faces forward while leaving your arms in their position. Look where your hands are.

They're no longer way around your body. They're much more in front of you.

Go farther into the backswing and do it again. Turn. Stop. Return your torso to centre.

Your arms are moving while your torso is turning underneath them.

Put those two movements together and suddenly you have something that looks like a golf swing.

What Do Your Arms Do in the Downswing?

Take that same experiment all the way to the top. Make your normal backswing. Stop. Return your torso to centre while maintaining your arm position relative to your body.

Your arms have essentially moved up.

Now start the downswing and stop partway down. Return your torso to centre again.

Your trail elbow is much closer to your stomach and the arms have moved down.

That's the basic arm movement: Up → Down.

The rotation of your body turns that relatively simple movement into the golf swing you see.

Don't Throw Your Arms Out Toward the Golf Ball

A lot of golfers get to the top and instinctively send their arms out toward the golf ball.

Instead, feel the arms working down.

Imagine you're holding a ball and throwing it hard into the ground. That's much closer to the movement.

When I'm hitting it my best, my arms feel like they're moving down while my body turns through.

Arms out → hands flip → try to time impact

becomes:

Arms down → body turns → club comes through.

Where Does Power Come From in the Golf Swing?

I actually started exploring this while working on speed.

I wanted to know which muscles were powering the golf swing because if I wanted to swing faster, I needed to understand what movement I was actually trying to make stronger.

From the top there's a powerful pulling-down motion. Think about the muscles you'd use if you were pulling something hard from above you toward the ground.

Practice the arm movement by itself: Up. Down.

Then add the turn.

Arm movement + body rotation = golf swing.

What Should Your Body Do in the Golf Swing?

Now let's add the other half of the movement.

With an iron, we're not trying to squeeze every possible yard out of the golf club.

If my 7-iron goes 170 yards, great. I want it to go 170 yards predictably.

That's what we're looking for with iron play: predictable distance and predictable direction.

So when we're talking about body rotation with an iron, I want a movement that's repeatable.

And the easiest way to understand that movement is to start at impact.

Watch: What Your Lower Body Does in the Golf Swing

Start With Impact, Not Your Backswing

Take your setup and move yourself into a good impact position.

For a right-handed golfer, your lead leg will be straighter while your trail leg remains bent. Your body has rotated toward the target. Your hands are forward.

Now instead of asking “How do I get here?”, work backward.

Move your lower body back toward its starting position and allow your upper body to move with it.

You'll start seeing where the club has to be before the body's rotation brings everything through.

What Should Your Legs Do Through Impact?

For a right-handed golfer:

Lead leg → straightens
Trail leg → remains bent

As the lead leg straightens, your body turns. And as your body turns, it brings the club through the golf ball.

Take the club back a short distance toward your trail foot. Now straighten your lead leg.

Your body turns. The club comes through.

For a left-handed golfer, simply reverse the sides.

A Simple Golf Rotation Drill You Can Do at Home

You don't need to make full swings to learn this. You don't even need real golf balls.

Use a whiffle ball or ping-pong ball in your living room if you want.

Set up normally. Take the club back a short distance toward your trail foot.

Straighten the lead leg → turn → bring the club through.

Start slowly. Once you can do the movement repeatedly, add a little speed. Then a little more.

Because if you can't make the movement slowly, you're probably not going to suddenly make it correctly when you're swinging hard.

How to Find Your Golf Impact Position

Now we can put the arms and body together.

This is the part of the golf swing I care about most.

You can have a backswing that looks strange. You can have a swing that doesn't look anything like the player beside you.

But the golf ball only cares about what the club is doing when it reaches the ball.

That's why I like to define the important part of the swing as roughly the foot before the golf ball and the foot after it.

That's your impact zone.

Watch: How to Find Your Golf Impact Position

Step 1: Check Your Golf Grip

Before finding your impact position, make sure your grip gives you a reasonable starting point.

For a right-handed golfer, take the club in your lead hand and position it underneath the meaty part of your hand. Extend that arm forward.

The club should sit relatively straight up and down rather than pointing dramatically left or right.

Then place your trail hand on the club. A useful guide is having the line created by your thumb and hand point generally toward your trail shoulder.

It doesn't have to be millimetre-perfect. We're simply giving ourselves a solid starting position.

Step 2: Find a Natural Setup

Put your feet together and centre the golf ball between them.

Hold your arms naturally in front of you and then bend forward into your golf posture. Let your hands find where they naturally want to hang.

Don't reach way out toward the golf ball. Don't pull your hands artificially close to your legs.

Once you've found that comfortable posture, widen your stance while keeping the ball centred for this drill.

Step 3: Move the Club Behind Your Trail Foot

Take the club back until it's approximately behind your trail foot.

You don't need a full backswing. We're isolating the movement that matters around impact.

Your trail arm will naturally have a little bend.

Don't manipulate your wrists or try to manufacture an impact position with your hands. We're going to let the body bring the club there.

Step 4: Turn Into Your Impact Position

From that position, begin straightening your lead leg while keeping your trail leg bent.

Use that movement to rotate your body toward the ball. Don't change anything with your hands or wrists.

Turn into it. Now stop.

You should see:

• Forward shaft lean
• Straight lead arm
• Slightly bent trail arm
• Body rotated toward the target

That's your impact position.

The Most Important Golf Swing Drill You Can Practice

Once you've found that position, don't immediately make a full swing.

Hit tiny shots from there.

A whiffle ball in your living room works. A net works. A driving range works.

The distance doesn't matter. Ten yards is completely fine.

You're asking one question:

Can I hit the golf ball straight and solid from my impact position?

Set the club behind your trail foot. Find impact. Turn through. Hit the little shot.

Then do it again. And again. And again.

I've been playing and teaching golf for decades, and whenever something starts going wrong in my own swing, this is where I come back.

Impact first.

Once that's right, we add speed.

Find Impact → Repeat Impact → Add Speed

That's the progression.

Don't chase speed before you can control impact.

Find the position. Practice the position. Then gradually make the movement bigger and faster without losing it.

Impact → Half swing → Three-quarter swing → Full swing → Speed

Instead of starting with a giant full swing and trying to fix everything that's happening inside it, we're building outward from the one part of the swing that actually hits the golf ball.

3 Golf Swing Drills for More Consistency

Once you understand what the arms and body are doing and where you want them to meet at impact, you need to make the movement repeatable.

These are three of my favourite drills for doing exactly that.

Watch: 3 Golf Swing Drills for Consistent Contact

Drill #1: The Half and Full

Here's the idea: Half backswing. Full power through.

Take the club approximately halfway back.

Then start the downswing with your lower body and hit through with speed.

For a right-handed golfer, I like thinking about the left hip or left butt cheek moving backward as if you're trying to touch a wall behind you.

Halfway back → lower body starts → pull through.

You may be surprised by how much speed you can produce with such a short backswing.

But the real purpose isn't distance. We're training your body to create a powerful and repeatable impact position.

Sometimes I'll hit almost an entire bucket doing this drill, hit two full swings at the end and call it good.

Make Your Impact Zone Longer

Consistency is partly about making the area where the club is behaving correctly through the golf ball as predictable as possible.

We don't want everything depending on a perfectly timed flip of the hands.

Instead, feel like you're pulling the handle through the golf ball.

You're learning to use the bigger movements of the body to bring the club through instead of asking your hands to save the shot at the last second.

Drill #2: The Bottle Drill and the Good Loop

Place a bottle, headcover or similar object on the ground just inside the club's path.

Outside the object going back.
Inside the object coming down.

Outside → Inside.

When you put those movements together, you'll see a small loop in the club's path.

I call this the Good Loop.

You may hit some draws. You might even hook a few while you're exaggerating it. That's okay.

The purpose is to groove the idea of the club working inside on the way down rather than coming over the top.

Outside going back → inside coming down.

Drill #3: The Towel Drill

Put a towel underneath your lead armpit.

Now make shorter Half and Full swings while keeping the towel underneath your arm through the hitting area.

This helps keep your lead arm connected to your body.

Your arms aren't supposed to fly outward toward the golf ball while your body sits still.

We're trying to get the arms and body working together.

Make the short swings repeatedly. Feel the handle being pulled through.

Then remove the towel and hit a few normal shots while trying to reproduce that same connected feeling.

How to Practice Golf Swing Rotation for Consistency

Don't stand on the driving range thinking:

Arms. Shoulders. Hips. Legs. Hands. Clubface. Impact.

That's not going to make golf easier.

Break the movement apart while you're learning.

Understand what your arms are doing. Understand what your lower body is doing. Find your impact position. Then use drills to put everything together.

The goal isn't to create a golf swing that looks perfect when somebody pauses a video.

It's to create a movement that lets you arrive at the golf ball in a predictable impact position over and over again.

That's consistency.

Build Your Golf Swing Backward From Impact

If there's one idea I want you to take away from this, it's this:

Don't build your golf swing around how you think it's supposed to look.

Start with what matters.

Impact.

Find the position where you can deliver the club to the golf ball solidly and predictably. Then work backward from there.

That's the same process I teach in 30 Days to Better Ball Striking.

We start around impact and progressively build the swing bigger:

Impact → Half Swing → Three-Quarter Swing → Full Swing

You're not collecting random swing tips and hoping one sticks. You're building a golf swing around the position that actually produces the shot.

If you want me to help walk you through each step, and build your golf swing from impact backwards, I've laid it all out in an easy to follow video program with coaching help.

How to Rotate in the Golf Swing: The Simple Version

If all of this feels like a lot, come back to the basics.

Your arms aren't making the giant circular movement you think you're seeing. They're working much more up and down.

Your lower body creates rotation. For a right-handed golfer, feel the lead leg straightening while the trail leg stays bent as the body turns through.

Those movements meet at impact.

Find that position first. Then make the swing gradually bigger without losing it.

Finally: Add speed.

Remember four things:

ARMS → ROTATION → IMPACT → SPEED

Learn the pieces. Put them together. Then go hit golf balls.
