Martyna Kierczynska: Poland’s Muay Thai Prodigy Storming ONE Championship
From Polish Roots to the World Stage: The Rise of Martyna Kierczynska
In the heart-pounding world of Muay Thai, where elbows slice like blades and knees crash like thunder, Martyna Kierczynska stands out as one of Europe’s most electrifying talents. Born on April 9, 2002, in Głogów, Poland, the 23-year-old sensation is rewriting the narrative for female fighters across the continent. With a resume packed with European titles, global medals, and explosive ONE Championship performances, her journey from local gyms to the iconic Lumpinee Stadium reads like pure combat destiny.
As of September 2025, with her sights set firmly on the ONE Women’s Atomweight Muay Thai World Title, the Polish powerhouse continues to captivate fans worldwide. Here’s the story behind her meteoric rise.
Early Beginnings: From Głogów to Greatness
Głogów, a quiet industrial town in southwestern Poland, isn’t the typical birthplace of a Muay Thai star. But it’s where Martyna first discovered her passion at just ten years old. Drawn to Muay Thai for its raw intensity, she trained at the renowned Legion Głogów under respected coach Maciej Dominczak. Their bond became the foundation of her evolution—from a focused young athlete to a national standout. Her amateur accomplishments proved exceptional:
- 2023 European Games Gold (54kg)
- World Combat Games Gold
- World Games Silver
- WMC Muay Thai World Championship (2023)
Her early success established her as one of Europe’s most promising strikers, and as Martyna said, “Muay Thai isn’t just a sport for me—it’s my language.”
Training in Thailand: Phuket, Mai Karon, and a Fighter Reborn
To rise among the world’s best, Martyna knew she needed the birthplace of the sport: Thailand.
Before her international breakout, she traveled to Phuket for an intensive training camp at Mai Karon Muay Thai, a traditional gym famed for its champion trainers and friendly atmosphere. Located between Kata and Patong, it became her crucible.
Here’s what defined her Thai transformation:
- Grueling clinch sessions with seasoned Thai pros
- Endless rounds of pad work under blistering heat
- Cultural immersion through the Wai Kru, rituals, and rhythm of Thai training
- Strengthening her elbows, knees, and pressure-based style
“Phuket changed everything,” she reflected. “The heat, the pace, the respect—it sharpened my fire.”
This camp forged the relentless, high-output fighter fans now recognize inside ONE Championship.

Kierczynska’s professional career shifted gears in 2024 when she signed with ONE Championship, the world’s largest martial arts organization.

The Polish Destroyer: Fighting Style & Mindset
Martyna Kierczynska’s style is relentless—built from pressure, precision, and unbreakable spirit.
Why She’s So Dangerous
- Forward-pressure orthodox stance
- High-volume punching combinations
- Sharp elbows and slicing knees learned in Thailand

Her self-described style? “I’m a buzzsaw.”
Her support team fuels her success: coach Dominczak, her Legion Głogów family, and her parents—her emotional anchors. After earning silver at the 2025 World Games in Chengdu, despite a controversial decision, Martyna’s determination only grew. Even Stamp Fairtex acknowledged her talent: “Martyna has something special—she’s one for the future.”
On the Hunt for Gold: Title Dreams and 2025 Plans
As September 2025 unfolds, Martyna is firmly positioned as a top atomweight, targeting the ONE Women’s Atomweight Muay Thai World Title, currently held by Allycia Hellen Rodrigues. “Step by step until I get the belt,” she promises. Rumors hint at a title fight toward the end of the year, possibly against the winner of Rodrigues vs. Persson. Martyna says she’s ready:
“If they call me tomorrow for a title fight, I say yes.”
To prepare, another camp in Phuket at Mai Karon Muay Thai is likely—sparring with world-class partners and refining her weapons for the biggest moment of her career. She is now inspiring a new generation of Polish female fighters while aiming to become the country’s first ONE Champion.
