How Olympic Champion Sunisa Lee Uses Personal Mantras to Build Mental Strength

Sunisa Lee captured the world’s attention at the Tokyo 2020 Olympics when she won the all-around gold medal in gymnastics—a stunning achievement that capped a journey filled with injuries, family health crises, and the immense pressure of elite competition. But what sets Lee apart isn’t just her technical brilliance on the uneven bars or her graceful balance beam routines; it’s her extraordinary mental resilience. The 20-year-old athlete has been open about relying on a set of personal mantras to navigate setbacks and stay grounded. These simple, repeatable phrases act as mental anchors, helping her refocus when the stakes are highest. In this article, we’ll explore Sunisa Lee’s favorite mantras, the psychology behind why they work, and how you can create your own affirmations to overcome challenges in sports, work, or personal life.

Why Personal Mantras Matter More Than You Think

Personal mantras are short, positive statements that you repeat to yourself, often during moments of stress, self-doubt, or high pressure. They are not empty words—they are tools for cognitive reframing. When you repeat a mantra, you train your brain to replace negative thought loops with constructive, empowering ones. For athletes like Sunisa Lee, mantras serve several critical functions:

  • Anchoring focus. A mantra pulls you back to the present moment when your mind starts racing about outcomes or past mistakes.
  • Regulating emotions. Phrases like “breathe, stay calm” activate the parasympathetic nervous system, lowering heart rate and stress hormones.
  • Boosting self-efficacy. Repeating “I am enough” reinforces a sense of worth and capability, which is essential after a fall or a poor performance.
  • Building resilience. Mantras become mental habits that create a default response to adversity—instead of panicking, you repeat your phrase and stay the course.

Research in sports psychology supports the effectiveness of self-talk strategies. A 2021 meta-analysis published in Psychology of Sport and Exercise found that instructional and motivational self-talk significantly improved performance across a range of tasks, from strength exercises to precision sports. Personal mantras fall into the motivational category, helping athletes maintain effort and persistence.

Sunisa Lee’s Favorite Mantras: In Her Own Words

During interviews and media appearances, Sunisa Lee has shared several mantras that she relies on in training and competition. Each one addresses a specific mental challenge—overwhelm, self-doubt, anxiety, or fatigue. Let’s examine each in detail.

“One step at a time.”

This mantra is all about staying present. In gymnastics, a routine consists of dozens of intricate movements. If an athlete thinks about the final landing before she has even set for a back handspring, she risks a costly mistake. Sunisa Lee uses “one step at a time” to break down the immense pressure of an Olympic final into manageable actions. It’s a simple but profound reminder that the only moment you can control is the one you are in right now. This approach also applies to life outside the gym: when recovering from an ankle injury or juggling school and training, focusing on the next small step prevents overwhelm.

“I am enough.”

Perhaps the most emotionally charged of Lee’s mantras, “I am enough” is a direct counterpunch to feelings of inadequacy. Lee has faced her share of doubts—after a fall in training, when comparisons to other gymnasts like Simone Biles arise, or during her battle with kidney issues that threatened her college career at Auburn University. This mantra reminds her that her worth is not tied to a score, a medal, or a perfect routine. For anyone struggling with impostor syndrome or perfectionism, repeating “I am enough” can quiet the inner critic and restore self-compassion.

“Breathe, stay calm.”

Anxiety is a universal experience, especially under the glaring lights of a sold-out arena. Lee has described how her heart races before a floor exercise. Instead of fighting the adrenaline, she uses this mantra to channel it. “Breathe, stay calm” combines a physical cue (taking a deep breath) with a mental intention (remaining composed). The act of deep breathing stimulates the vagus nerve, activating the body’s relaxation response. This technique is well-documented in mindfulness practices and is used by elite performers from Navy SEALs to concert pianists.

“Keep pushing forward.”

Resilience is about continuing when quitting would be easier. After Lee’s aunt and uncle died from COVID-19 in 2020, she considered stepping away from gymnastics entirely. Instead, she chose to keep training, using this mantra to honor her family and her own dreams. “Keep pushing forward” acknowledges that progress is not always linear—there will be setbacks, pain, and exhaustion. But the act of moving forward, even slowly, builds momentum and character.

“I’ve done this a thousand times.”

Although less frequently quoted, Lee has also shared that she reminds herself of her preparation. This mantra activates muscle memory and confidence. When you have drilled a skill repeatedly, your body knows what to do; the mind just needs to get out of the way. This phrase is particularly useful before high-difficulty elements like her release moves on the uneven bars.

The Science Behind Mantras: Why Repetition Works

Mantras are not just feel-good slogans—they have a biological basis. When you repeat a phrase, you engage the brain’s reticular activating system (RAS), which filters information and prioritizes what you focus on. Over time, the mantra becomes a cognitive shortcut. The brain also releases dopamine when you successfully use a mantra to calm down or refocus, reinforcing the behavior. Additionally, neuroimaging studies show that positive self-talk activates regions of the prefrontal cortex associated with emotional regulation and problem-solving, while dampening activity in the amygdala, the brain’s fear center.

A study from the University of Michigan found that participants who repeated a self-affirmation mantra before a stressful task had lower cortisol levels and performed better than a control group. The key is consistency—repeating the mantra enough times that it becomes an automatic response, much like a gymnast’s routines become second nature.

How to Create Your Own Personal Mantras

You don’t have to be an Olympic athlete to benefit from mantras. Here’s a step-by-step guide to crafting phrases that resonate with you.

Step 1: Identify Your Core Challenges

What situations trigger anxiety, self-doubt, or procrastination? Maybe it’s a big presentation at work, a difficult conversation, or a fitness goal you’ve been avoiding. Write down the specific thoughts that arise in those moments—for example, “I’m going to mess this up” or “I’m not good enough.”

Step 2: Create a Counter Statement

Your mantra should directly address that negative thought. If you think “I always choke under pressure,” a counter mantra could be “I thrive when it matters most.” If you doubt your preparation, try “I have done everything I can—now I execute.” Make sure the phrase is short, present tense, and personal (use “I” statements).

Step 3: Test It in Low-Stakes Settings

Start using your mantra during small daily stressors, like a tough commute or a workout. Notice how it makes you feel. If it doesn’t land, tweak the wording until it feels authentic. Sunisa Lee likely refined her mantras through trial and error during practice before they became competition-ready.

Step 4: Pair It with a Physical Anchor

To strengthen the association, repeat your mantra while taking a deep breath, touching your thumb and forefinger together, or looking at a specific object. This creates a conditioned response—eventually, just performing the physical action can trigger the calm or confidence you need.

Step 5: Use It Regularly

Repetition is the secret sauce. Say your mantra several times a day, especially in the morning and before challenging situations. Write it on a sticky note, set it as your phone wallpaper, or record yourself saying it. Over time, it will become an effortless mental reflex.

Applying Mantras Beyond Sports: Real-Life Scenarios

The same mantras Sunisa Lee uses in the gym can be adapted for everyday life. Here are a few examples:

In the workplace: Before a high-stakes meeting, repeat “One step at a time” to avoid being overwhelmed by the agenda. Use “I am enough” before asking for a promotion or presenting a new idea.

In academics: When studying for a difficult exam, “Keep pushing forward” can help you power through a long study session. “Breathe, stay calm” is perfect for the minutes before a test begins.

In relationships: During a heated argument, silently repeating “Stay calm, listen first” can prevent you from saying something you’ll regret.

In health and fitness: When you’re tempted to skip a workout, “I’ve done this a thousand times” reminds you of your capability. After a setback like an injury, “One step at a time” supports a gradual recovery.

Common Mistakes to Avoid When Using Mantras

While mantras are simple, many people misuse them and then dismiss them as ineffective. Avoid these pitfalls:

  • Using vague or generic phrases. “I will be successful” is too broad. Your mantra must feel true and specific to your struggle.
  • Neglecting repetition. Saying a mantra once before a big event won’t override months of negative self-talk. Daily practice is essential.
  • Expecting instant results. Mental training is like physical training—it takes weeks to see change. Be patient.
  • Using a mantra that conflicts with your beliefs. If deep down you don’t believe “I am the best in the world,” your brain will reject it. Start with something believable like “I am getting better every day.”
  • Not pairing action with mantras. Mantras are not a substitute for preparation. Lee still puts in countless hours in the gym; the mantra just optimizes her mindset during that work.

How Sunisa Lee’s Mantras Fit Into Her Broader Mental Training Toolkit

Mantras are only one piece of Lee’s mental preparation. She also works with a sports psychologist, practices visualization (seeing herself hit perfect routines before she steps on the mat), and uses breathing exercises to lower her heart rate. In interviews, she has mentioned journaling and talking openly with her coach about pressure. The mantras serve as quick, portable tools that she can deploy in the moments between events—when she’s waiting for her score, walking to the beam, or standing behind the vault runway.

This integrated approach is backed by best practices in elite sports. According to the American Psychological Association, the most effective mental training combines self-talk, imagery, goal setting, and relaxation techniques. Mantras are the “micro” intervention that reinforces the other “macro” strategies.

Stories from Other Athletes Who Use Mantras

Sunisa Lee is in good company. Many top athletes credit mantras for their success:

  • Serena Williams often repeated “Come on!” and “I can do this”—short, aggressive mantras that fired her up during tense points.
  • Michael Phelps used “I will not quit” and “Just keep swimming” to push through grueling training sessions.
  • Simone Biles has spoken about using affirmations like “I have the ability” and “I am mentally strong” to manage the spotlight and her twists in the air.
  • Kobe Bryant famously told himself “Mamba Mentality”—not a traditional mantra, but a defining phrase that summed up his relentless work ethic and confidence.

These examples show that the specific wording matters less than the personal meaning behind it. What works for one athlete may not work for another. That’s why Sunisa Lee’s mantras are uniquely hers—they grew from her own experiences of loss, injury, and triumph.
