You spent weeks on that presentation. You rewrote the opening three times. You practiced in front of colleagues. You timed it to the second. You had your cue cards organized, your slides perfect, your statistics on point and irrefutable.


A performer seen from behind stands in a spotlight, arms outstretched on a dark blue stage, creating a dramatic mood.

Then you walked into the room, and something went wrong.


Not with the words. The words were fine. Not because of a lack of preparation; you had worked on this for weeks! It was something else. Something harder to name. The room did not lean in the way you expected. The energy fell flat. You felt disconnected from your own material. You finished. You sat down. You knew it did not impact the room the way it should have.


Want to know what happened? It’s simple: you forgot to rehearse your whole body as part of the presentation.


I have spent 25 years watching bodies under pressure


I come to public speaking coaching from an unusual direction. I am a former dance choreographer and movement coach turned film director who spent more than a decade observing how a weak or disconnected body can sabotage even the best performance. If this body disconnect can deflate a professional performer’s presentation like a flat tire, imagine what can happen to an executive who has the intellect to nail all the bullet points on their cue cards or PowerPoint presentation but is totally undermined by slouching shoulders, buckling knees or a meandering, directionless body.


Over time, I have watched hundreds of bodies under pressure. Bodies trying to perform. Bodies trying to persuade. Bodies trying to lead. I have noticed something that, given we are in the age of talking-head Zoom calls and virtual, faceless Slack messaging, everyone seems to forget when they actually step in front of a group of people to speak: the body.


The people who command a room are not always the best speakers. They are the ones who know how to stay grounded and fully present in their bodies while they are speaking.


Speeches, group meetings and corporate presentations are about more than words. They are about presence. How a body tells a story before a single word is spoken. How stillness can command more attention than motion. How the direction of your gaze tells an entire room where to look. How your feet, yes, your feet, are either anchoring you to your authority or quietly undermining everything you say.


Your body is not the backdrop for your presentation. It is the presentation.


There are three things I look for immediately when I watch an executive present. Three points in the body that most public speakers completely neglect. Fixing them, even partially, transforms how a room receives you before you ever open your mouth.


1. Your center: Know where your story is coming from


Before you walk into any room, a boardroom, a stage, a conference call, ask yourself one question: Where is this story coming from?


Most executives speak from their head. The data lives there. The strategy lives there. The quarterly numbers live there. That is fine, for about three minutes. After three minutes, a head-only presentation loses the room because the room is made of human beings, not spreadsheets.


Ask yourself: Does this presentation have a heart connection? A gut connection? Will this information save someone’s job, change someone’s life, or solve a problem that keeps someone awake at three in the morning? If yes, find that connection and let it live in your body, not just your analytical mind and expertly drafted slides.


Here is the exercise I give every client before a major presentation: Find a quiet room. Stand up. Walk slowly. Do not analyze. Do not rehearse. Just ask your body: Where is this story coming from? Let the answer be physical. Let it land somewhere in your torso. Then speak the first line of your presentation out loud from that place. Just the first line. Notice how it sounds different when it comes from somewhere real.


That is your center. That is where the bridge between your words and your audience gets built.


2. Your physical direction: Your gaze tells everyone in the room how to follow your thought process


I can tell within thirty seconds whether a presenter has control of their room. Not by what they say, but by where and how they look at the audience.


  • Meandering gaze, eyes moving randomly across the room with no intention, reads as lost. The room feels it; people become unsure of where to direct their focus and get restless.

  • Downward gaze, eyes dropping to notes, slides or the floor, reads as insecure.

  • Craning gaze, neck extended, chin jutting three feet ahead of you, reads as desperate or as reaching for an idea you yourself are not sure you believe in.


Slouching collapses your voice physically, your diaphragm cannot expand fully when your chest is caved in. It’s not that you need a loud voice, but it needs to feel expansive and supported, not crushed or choked off. Slouching also signals to every person in the room that you don’t feel safe and sure of your right to be there.


The fix is simple and immediate. Pick three points (or people) in the room, left, center, right. Move your gaze deliberately and slowly between them. Land on each point long enough to complete a full thought. This is not the scanning technique most coaches teach. This is intentional direction. You are telling the room you know where you are and where you are headed, and they can feel safe following you.


When your gaze has direction, your whole body aligns behind it. Your spine lengthens. Your shoulders drop. Your chin levels. Your voice finds its full resonance. All of that happens automatically, from one decision about where to look.


3. Your feet: The foundation nobody talks about


This is the one that surprises people I work with the most. It is the one I am most certain of.


You cannot build a house without a foundation. You cannot stand on a stage, or at the head of a boardroom table, without knowing where your feet are.


Stage fright, opening-night nerves, presentation anxiety, call it what you want. What it does physically is cut you off from the ground. Your weight shifts to the edges of your feet. Your knees lock or, worse, buckle. Your glutes clench, locking your hips. Your breath moves up into your chest and gets shallow. Everything you prepared, every line, every statistic, every carefully crafted transition, starts to drift. Not because you forgot it. Because you have nothing to stand on.


Your feet are your anchor to your own authority.


Before your next presentation, think deliberately about grounding yourself. Rehearse in your bare feet a few times, really feeling the floor beneath your toes. Then rehearse in a few different pairs of shoes. With your bare feet and with your shoes, take note of how they connect you to the floor. A heel that is too high pitches your weight forward and destabilizes your entire alignment. A sole that is too soft gives you nothing to press into. What you want is a shoe that lets you feel the ground and press back against it.


Now, just like your eyes have fixed points you can rely on, your feet do too. There are three basic stances in public speaking: standing still, which is used for the punchline or a major point you are trying to drive home; traveling, which is used to move with the flow of an idea; and returning, which means returning to the center of the stage, usually to end a thought or start a new one. Notice I did not say meandering. Travel from one fixed point to another, then stop there. Be deliberate. Traveling is a way to release tension and nerves and gather yourself if you get lost. Practice this: pick two places you can travel to, practice pausing and returning, and watch the awkward foot scuffling and meandering start to fade away as decisive movements take their place.


You are ready to perform. Almost.


The solution


I would find ways to practice these techniques long before you have a public speech on the line.


Getting the words connected to the body is vital to the success of your presentation. Ask a coach to help you; they will be the most honest observer and will be able to give you actionable suggestions for improving your posture and your center. Try running the speech silently in your mind as you ride the spin bike, go through your yoga flow or even lift weights. This connection between the body, the words and the intention of how you want the audience to feel can only come together if you practice.


Because it takes more than just the words to command a room. It takes your whole body, from the base of your feet to the top of your head. Need help with your next public speaking event? I can help you embody the speech, get it grounded and make it part of your whole being before you get on stage.
