It occurred to me recently that we throw around words assuming everyone understands them.

I talk with my coaching clients about this all the time—but I want to make sure I’m not guilty of it too.

We say things like:

1. Belly breathing

2. Diaphragmatic breathing

3. Abdominal breathing

4. Get grounded

But what are we really talking about?

What is actually happening in your body?

And how does any of this deepen resonance, stabilize your voice, and help you communicate authority—without forcing it?

Let’s unpack it.

The Anatomy of a Breath

Breathing involves three main players:

1. The diaphragm

2. The intercostal muscles (the muscles between your ribs)

3. The accessory muscles (around your neck and shoulders)

The diaphragm is a dome-shaped muscle that separates your thoracic cavity (lungs and heart) from your abdominal cavity. It behaves a bit like a jellyfish: when it activates, it flattens and lowers. When it relaxes, it domes back up.

Here’s how inhalation works:

1. The diaphragm lowers.

2. The lungs stretch downward and fill with air.

3. The intercostals expand and stabilize the rib cage, allowing the lungs to widen.

4. If needed, accessory muscles lift the upper ribs and sternum for additional expansion.

Down. Out. Up.

That’s a full inhale.

When you exhale:

1. The diaphragm relaxes and domes upward.

2. The lungs and rib cage recoil elastically.

3. Air flows out naturally.

Efficient. Coordinated. Designed beautifully.

Where Most People Go Wrong

Here’s what I see constantly.

When I ask new clients to take a “deep breath,” they lift their shoulders.

They initiate with the accessory muscles. Maybe the intercostals.

They think they’re breathing deeply.

They’re not.

They’re taking a high, shallow breath.

Now—is that always bad? No. During aerobic exercise, you absolutely recruit accessory muscles first.

But if that becomes your default breathing pattern, especially while speaking, you’re reinforcing a mild fight-or-flight state.

Shallow, upper-chest breathing:

1. Keeps the sympathetic nervous system activated

2. Maintains tension around the neck and shoulders

3. Increases muscular engagement around the larynx

4. Produces tight, constricted vocal tone

You cannot expect a relaxed, resonant, flexible voice while holding unnecessary tension.

It doesn’t work that way.

What “Belly Breathing” Actually Is

When the diaphragm descends properly, it presses gently into the abdominal cavity.

The organs shift slightly downward and outward.

The abdominal wall expands—not because you’re pushing it—but because it’s accommodating movement from above.

That expansion is what people refer to as “belly breathing.”

It’s not about forcing your stomach out.

It’s about allowing the diaphragm to do its job.

What “Grounded” Really Means

Grounded breathing is simply diaphragmatic breathing described in functional terms.

It means:

1. Less lift in the shoulders

2. Less activation in the neck

3. Less upper-chest dominance

4. More balanced rib expansion

5. More abdominal responsiveness

Neurologically, it favors parasympathetic regulation—the “rest and regulate” system—rather than the mobilized “fight or flight” state.

Grounded doesn’t mean sleepy.

It means ready—but not frantic.

It’s quiet control.

And that’s what authority feels like.

Try This Now

If you’re at your desk, try this:

1. Sit or stand tall.

2. Shift your weight slightly from heels to toes and find balance.

3. Place one hand on your chest.

4. Place the other hand near your belt line.

5. Inhale and allow expansion into the lower hand while keeping the upper hand relatively still.

It won’t be perfect.

Don’t force it.

Don’t brace your abdomen.

This is a coordination practice—not a performance.

Practice throughout the day. Try it in front of a mirror. Observe without judgment.

Why This Builds Vocal Authority

When you consistently access lower, regulated breathing:

1. Your nervous system stabilizes.

2. Your voice has a steady airflow source.

3. Your resonance deepens naturally.

4. Your range expands without strain.

5. You stop compensating with volume or bravado.

Authority doesn’t begin in your words.

It begins in your body.

And when your breath is regulated, your voice follows.

Until next time, keep fostering your voice.
