Wear your power.
Live your affirmation.
Build your beat.
Affirmation-named premium activewear by founder Kianna Michele Theus. Sports bras, leggings, bodysuits, jackets — every piece named with intention, designed in butter-soft quick-dry stretch fabric with sculpting silhouettes and breathable compression. 97 SKUs across the studio. Built to support the rhythm of a strong, aligned life — from studio to street.
KIMITH was born from healing.
I am Kianna Michele Theus. KIMITH started during the worst chapter of my family's life. My mother had a sudden cardiac arrest mid-speech. Her heart stopped for nearly twenty minutes before a friend's CPR and the paramedics revived her. Both my parents had been diagnosed with heart disease in their early forties. During my mother's recovery, I recognized my own undiagnosed depression, anxiety, and the way stress was quietly affecting my own body.
I started actually looking at what we feed our hearts. Not just food. Thoughts. Emotions. The content we scroll at 2 a.m. The people we keep close. I built KIMITH to make the daily practice of speaking well to yourself a piece of clothing you can put on. Every set is named with intention. Wear it like you mean it.
Our parallel mission — kimithkares.com — focuses on normalizing heart-disease-prevention practices in millennials and women of color. The clothing exists because the cause does. Every piece you wear is a quiet vote for the conversation we need to have about cardiovascular wellness, mental health, and the way the two are not separable.
— Kianna Michele Theus Founder + CEO · KIMITH BRANDTwelve affirmations, twelve cuts.
Each KIMITH affirmation maps to a real psychological intention — sourced to peer-reviewed cognitive-science literature. Read the affirmation. Wear the cut. Both halves matter.
The foundation of the brand. The 2016 Cascio neuroimaging study (Soc Cogn Affect Neurosci) showed that affirming intrinsic self-worth activates the ventromedial prefrontal cortex — the brain's self-relevance and reward region. Worn on bodysuits + tanks.
Reclaiming agency in the face of stress. Sherman & Cohen's foundational self-affirmation theory (2006) catalogued how affirming personal power buffers against threat-based stress. Worn on the flagship bodysuit.
Abundance as internal state, not external possession. The mantra reframes the relationship to scarcity-thinking. Worn on the perfect-fit jacket and the signature sports bras.
Wealth measured in health, time, relationships, and meaning — not only money. Read the brand's full Build Your Beat framework on cardiovascular and mental wellness in our journal.
Kristin Neff's research on self-compassion (UT Austin, 2003 onward) shows that wonder-affirming language reduces cortisol response to perceived failure. Worn on the high-rise leggings + halter-neck bras.
Present-moment awareness as practiced in Mindfulness-Based Stress Reduction (MBSR; Kabat-Zinn 1979). Worn on the brown + pink stretch flare leggings.
Reframes anxiety about progress into trust in present positioning. Worn on the slate-blue butter-soft sports bras + shorts.
Carol Dweck's growth-mindset research (Stanford, 2006 onward) showed that limitless-frame self-talk improves performance on novel tasks. Worn on the zipper bodysuits across colorways.
Frames identity as a process rather than a fixed state — supportive for nervous-system flexibility. Worn on the colorblock quick-dry butter bras.
A deliberate cognitive-reframing prompt — drawn from CBT (cognitive-behavioral therapy) practice. Worn on the buttery-soft long-sleeve crops.
Reframes intensity as fuel, not flaw. Worn on the cherry + brown sports-bra colorways.
A spiritual-but-not-religious framing of pacing — the antidote to hustle-culture urgency. Worn on the sculpt v-waist leggings.
Build your beat.
The brand was founded around cardiovascular wellness — both parents diagnosed with heart disease in their early forties. The American Heart Association's Life's Essential 8 framework (2022 update) names the eight modifiable factors that drive 80%+ of cardiovascular risk. Five of them happen during the kind of movement KIMITH was designed to support.
Light walking, gentle stretching. Where every session begins. Active recovery + general warm-up.
Steady-state movement — walking briskly, dance, easy yoga flow. Sustainable for 30–60 min.
The cardiovascular-development zone. Running, intervals, structured strength. Target zone for AHA-recommended weekly minutes.
Performance and lactate-threshold work. Sprints, HIIT, heavy compound lifts. Brief intervals only.
Maximum effort. Short bursts, fully recovered between. The intensity that builds VO₂ max in trained athletes.
Quick-Dry Butter — the fabric.
Quick-Dry Butter is KIMITH's proprietary label for the fabric across the leggings, bodysuits, sports bras, and tanks. The brand describes it as butter-soft, quick-dry stretch with breathable compression — designed to feel elevated against skin while delivering activewear performance.
All KIMITH pieces are designed for movement that ranges from low-impact yoga and pilates through moderate-intensity strength + cardio. The fabric's soft compression sculpts without restricting; the moisture management keeps the fabric dry through 60-90 minute sessions; the warmth is light enough for layered studio-to-street wear.

Founded around a cardiac arrest.
KIMITH BRAND exists because the founder watched her own family confront cardiovascular disease in their early forties. Her parallel nonprofit, KIMITH KARES (kimithkares.com), works to normalize heart-disease-prevention practices in millennials and women of color — populations the AHA's own statistics show are systematically under-screened and under-counseled.
Heart disease is the #1 killer of women in the United States per CDC and AHA data — surpassing all cancers combined. Roughly 80% of cardiovascular events are preventable through the AHA's Life's Essential 8 framework (2022). KIMITH frames its activewear as one quiet daily prompt — wear the affirmation, move the body, build the beat — toward those preventive habits.
This page is informational, not medical advice. KIMITH BRAND clothing is activewear, not a medical device or treatment. If you or a loved one are at risk for cardiovascular disease, work directly with your physician.
Studio questions.
Six things people actually want to know.
Who is the founder of KIMITH BRAND?
Kianna Michele Theus — CEO and founder, with a verifiable LinkedIn presence. The brand was started in the wake of her mother's cardiac arrest and her family's history with early-onset heart disease. Read her full letter on this page; the founder's story is the brand's origin, not a marketing veneer.
What is "Quick-Dry Butter" fabric?
It is the brand's label for the proprietary Lycra-and-soft-knit blend used across leggings, bodysuits, sports bras, and tanks. The brand-stated description is butter-soft, quick-dry stretch with breathable compression — moisture-wicking and four-way-stretch performance with a hand-feel closer to soft loungewear than typical performance fabric. The PDPs disclose Made in China; specific composition percentages are not published by the brand.
What does "Build Your Beat" mean?
It is the brand's wellness motto — connecting cardiovascular health (the founding cause) to the daily rhythm of intentional movement and self-talk. The phrase frames consistent low-to-moderate-intensity activity as the long-game way to build a sustainable cardiovascular baseline. Our companion article on AHA's Life's Essential 8 covers the underlying framework.
Are the affirmation product names really meaningful, or marketing?
Both. They are real psychological prompts — self-affirmation theory has 20+ years of peer-reviewed support (Sherman & Cohen 2006 onward), and the 2016 Cascio neuroimaging study showed measurable ventromedial PFC activation when subjects engaged with self-affirming language. The product name is also marketing — but it is marketing built on a real cognitive-science effect, not a hollow flourish. Our journal article on affirmations and the brain covers the literature.
How do I care for KIMITH activewear?
Cold wash inside-out, with similar colors. Lay flat to dry or low-tumble. No fabric softener — fabric softener coats performance fibers and reduces moisture-wicking. No bleach, no high heat. Stored folded, not hung (the soft-knit shoulders can stretch). With this routine, KIMITH pieces typically hold their fit and color for 18-36 months of regular wear.
Does KIMITH have a giveback program?
Yes. The brand operates a parallel nonprofit at kimithkares.com focused on heart-disease-prevention awareness and education in millennial and women-of-color populations. The clothing brand and the nonprofit are linked by mission and founder; specific giveback percentages and program details are published through the nonprofit's own channels.
