Warm up before you speak: why your voice and body need preparation
Any runners in the room? Any yogis? Anyone who likes to move their body?
Most of us wouldn’t launch straight into exercise without some kind of warm-up. We know our bodies need a moment to wake up, loosen off and get ready for what we are asking them to do.
And yet, when it comes to public speaking, so many people go in stone cold.
They step into a meeting, onto stage or in front of a camera without warming up at all — and then wonder why their voice cracks, their breath feels shallow or one leg starts doing its own tiny panic dance.
It makes no sense when you think about it.
Because communication is a physical act.
Public speaking is not just mental
We often treat speaking as if it is all about thinking. We focus on what we are going to say, how to structure it, how to remember it, how to sound intelligent.
But speaking does not just happen in your head.
Good communicators speak through their whole body. Their diaphragm, their breath, their face, their hands, their posture, their jaw, their tongue. All of it is involved.
And if those muscles are tight, cold or braced, it becomes much harder to speak with ease.
That is often when the voice sounds thinner than usual, the breath gets stuck higher in the chest, or the whole body starts to feel more shaky and less reliable.
Why warming up helps your voice
This is why warming up can be such a game-changer.
When you warm up before speaking, you are not doing something unnecessary or theatrical. You are helping your voice and body do the job you are about to ask of them.
A simple public speaking warm-up can help you:
breathe more deeply and steadily
release unnecessary tension
access more vocal range and resonance
feel more grounded in your body
speak with more freedom, energy and presence
In other words, it helps you sound more like yourself — but at your best.
Why clients are often sceptical at first
This is one of my favourite shifts to watch in clients.
Time and again, I suggest a warm-up — maybe a bit of humming, maybe stretching out the side body or back body, maybe some breath work — and I get the look.
That slightly sceptical, “Really? Is this what we are doing?” look.
And then they do it.
And then they speak.
And then it is always some version of: Wow. That made a massive difference.
Because it does.
Sometimes the voice drops in. Sometimes the breath settles. Sometimes the whole person just sounds more present, more connected and more at ease.
It is simple, but it is powerful.
Simple ways to warm up before public speaking
You do not need a big routine. Even a few minutes can make a noticeable difference.
Before a presentation, meeting or speaking opportunity, try:
humming gently to wake up your voice
stretching your side body and upper back
rolling your shoulders and loosening your neck
taking a few slower, fuller breaths
softening your jaw and waking up your face
These kinds of voice warm-up exercises help your body prepare to communicate, rather than expecting it to go from zero to performance mode instantly.
Executive presence lives in the body too
A lot of people think executive presence is about what you wear, how you stand or whether you sound polished.
But presence lives in the body too.
When your breath is flowing, your voice is warm and your body is working with you rather than against you, you naturally come across as more grounded, more confident and more connected.
That is part of why warming up matters so much. It is not just about protecting your voice. It is about helping you show up fully.
Try it and see
If you have never warmed up before speaking, try it.
Not because you need to become a performer. Not because you need a complicated routine. Just because your body deserves a bit of preparation before you ask it to communicate under pressure.
Communication is physical.
And when you warm the body up, the voice often follows.
Try it and see.
