Mouth Warm-Up Exercises to Ease Nerves Before a Presentation

2026-06-11 · about 4 min read

Control shaking through the body, not willpower

If your heart races and your voice shakes right before a presentation, it is not because you lack willpower. It is because your body has entered tension mode. The more you tell yourself, “Don’t shake,” the more you may shake. Instead, when you directly relax your breathing and muscles, your body recognizes that this is not a dangerous situation and begins to calm down.

Step 1: Exhale slowly to lower your heart rate

When you are nervous, your breathing becomes shallow and fast. Repeat this breath five times: inhale for 4 seconds and exhale for 6 seconds. The key is to make the exhale longer than the inhale. As you exhale, the parasympathetic nervous system is activated, your heart rate drops, and voice trembling decreases.

Step 2: Loosen your stiff mouth and tongue

  1. Open your mouth wide in exaggerated “ah, eh, ee, oh, oo” shapes 5 times.
  2. Close your lips and exhale while vibrating them with a “brrr” sound, also known as a lip trill, for 10 seconds.
  3. Place your tongue on the roof of your mouth and quickly make a clicking sound 10 times.
  4. Read a hard-to-pronounce tongue twister slowly 3 times, then read it 3 times at increasing speed.
  5. Finally, say the first sentence of your presentation out loud 2 times, more clearly and a little more slowly than usual.

It is especially important to say your first sentence out loud beforehand. The most nervous moment in a presentation is the first 10 seconds, when you begin speaking. If that sentence already feels familiar in your mouth, the fear of starting is cut in half.

Step 3: Decide your gaze and posture in advance

Along with your warm-up, decide how you will stand. Lift your shoulders once in a shrug, then drop them to release tension, and place your feet shoulder-width apart for stability. If you decide in advance on three gaze points, the center of the audience and both far sides, you can avoid feeling lost about where to look during the presentation.

StepActionTime
Breathing4-second inhale, 6-second exhale x51 minute
Mouth warm-upVowel sounds + lip trill + tongue twister2 minutes
First sentenceSay the opening clearly 2 times1 minute
PostureRelax shoulders + set foot width + choose 3 gaze points1 minute

This 5-minute routine can easily be done in a restroom or a corner of the hallway. What matters is finishing it not right before entering the presentation room, but 5 minutes before your turn. If you loosen up too early, you may tense up again; if you start too late, you will only feel rushed.

💡
Note: Holding one sip of water in your mouth and swallowing it can ease a dry mouth caused by nerves. However, cold water constricts the vocal cords, so prepare lukewarm water.

Leave yourself a way to restart

When a plan gets interrupted, what you need is not a long reflection but the next first action. Simply leaving a note about how far you got today and what to start with next makes it easier to begin again. If you prepare a minimum version, you can keep your rhythm even on busy days.

Look again from your current situation

Break it down small enough to start

When a plan keeps getting pushed back, the goal is often too big or the first action is unclear. Instead of “do it well,” try wording it as something your hands can do right away, such as “open the document,” “write the first sentence,” or “close just one source.”

Starting small does not mean doing sloppy work. On many days, focus comes only after you begin, and even 5 minutes of work can make the next attempt feel a little less resistant.
