Known as the “Polish Terminator,” Kieliszkowski has captivated audiences with his explosive power, technical finesse, and relentless pursuit of the coveted World’s Strongest Man (WSM) title. Born on August 12, 1993, in Słubice, Poland, he has risen from a high school sports enthusiast to a global strongman icon, earning accolades such as two-time WSM runner-up and five-time Poland’s Strongest Man. Despite battling significant injuries, including a triceps tear and an Achilles tendon issue, Kieliszkowski’s resilience shone through with a triumphant victory at the 2024 Magnús Ver Magnússon Strongman Classic. As of April 17, 2025, with his sights set on the Europe’s Strongest Man competition, his journey is a testament to perseverance and raw talent. This biography delves into his life, career, and unyielding ambition to cement his legacy as one of the greatest strongmen in history.
Early Life: Seeds of Strength in Słubice
Mateusz Kieliszkowski was born in Słubice, a small Polish town near the German border, where his early years were shaped by a passion for physical challenges. Growing up, he towered over his peers, eventually reaching an imposing 6’5” and 331 pounds, a physique that would later become his greatest asset. His interest in strength sports sparked in high school at Zespół Szkół Licealnych i Zawodowych in Sulęcin, where he dabbled in various athletic pursuits. At 17, a friend’s impromptu strongman competition changed his trajectory. Treating it as a lark, Kieliszkowski unexpectedly won, igniting a fire to pursue the sport seriously. This serendipitous victory, marked the beginning of his transformation into a strongman prodigy.
Rise to Prominence: From Amateur to Elite
Kieliszkowski’s ascent in the strongman world was meteoric. In 2014, at just 21, he clinched the Arnold Amateur Strongman World Championships, earning a coveted invitation to the professional 2015 Arnold Strongman Classic. His debut was nothing short of sensational, securing 3rd place and making history as the youngest competitor ever at the event, as highlighted. This breakthrough showcased his raw potential and set the stage for a career filled with podium finishes and world records.
By 2016, Kieliszkowski was a rising star, placing 4th at both Europe’s Strongest Man and the Arnold Strongman Classic, and 7th in his first World’s Strongest Man appearance. In 2017, he claimed his first international title at the Arnold Africa, alongside a 4th-place finish at the Arnold Strongman Classic and 6th at WSM. His breakout came in 2018, when he surged to 2nd place at WSM, trailing only Hafþór Júlíus Björnsson. That year, he also won two Giants Live events, including the World Tour Finals, setting a world record in the Atlas Stones with a blistering 16.09 seconds.
In 2019, Kieliszkowski solidified his elite status, again finishing 2nd at WSM behind Martins Licis, taking 3rd at the Arnold Strongman Classic, and 2nd at Europe’s Strongest Man. He capped the year with victories at the World’s Ultimate Strongman in Dubai and Giants Live Wembley, despite competing with a torn bicep an achievement lauded . His dominance in events like the Cyr dumbbell press (145 kg/320 lb, world record) and timber carry (400 kg/882 lb in 7 seconds, world record) earned him the moniker “arguably the best athlete to have never won World’s Strongest Man,” as noted by Giants Live.
Injury Setbacks: A Test of Resilience
The early 2020s tested Kieliszkowski’s mettle. In 2020, despite winning four events at the Arnold Strongman Classic, he finished 2nd to Björnsson. A triceps injury later that year, compounded by surgical complications, forced him to withdraw from the 2020 WSM. This marked the beginning of a challenging period, with Kieliszkowski missing WSM in 2020 and 2021. In 2021, he competed sparingly, placing 2nd at World’s Ultimate Strongman and 4th at the Rogue Invitational, where he set a joint-world record in the Thor’s Hammer grip lift (125 kg/275 lb).
In 2022, persistent injuries, including hip issues and a urinary tract infection, led him to withdraw from both the Arnold Strongman Classic and WSM, as documented . He took the year to focus on recovery, undergoing double knee surgery. His comeback in 2023 was bittersweet: a 2nd-place finish at the Arnold Strongman Classic signaled his return, but injuries hampered his WSM performance, resulting in a group-stage exit for the first time. Later that year, he took 3rd at the Rogue Invitational, notably completing the Iron Bull sled pull, a feat no other competitor matched.
In 2024, Kieliszkowski started strong with another 2nd-place finish at the Arnold Strongman Classic, winning the Stone Medley. However, an Achilles tendon injury sustained during training forced him to withdraw from both Europe’s Strongest Man and WSM, as reported . Undeterred, he returned in November 2024, triumphing at the Magnús Ver Magnússon Strongman Classic in Iceland, where he set world records in the Natural Stone Block press (151 kg/333 lb) and Húsafell Stone carry (186 kg/410 lb for 68.02 meters).
Recent Competitions and 2025 Outlook
As of April 17, 2025, Kieliszkowski is gearing up for the Europe’s Strongest Man competition on April 5, 2025, in Leeds, marking his return to the Giants Live stage after a six-year hiatus. His withdrawal from the 2025 Arnold Strongman Classic, due to lingering Achilles concerns and the event’s demanding Frame Carry and Big Jerk, was a strategic move to ensure full recovery, as detailed in his YouTube video . Known for excelling in dynamic events like Loading Race, Conan’s Wheel, and Overhead Press, Kieliszkowski is a favorite to challenge defending champion Luke Stoltman and other contenders like Pavlo Kordiyaka and Aivars Šmaukstelis.
His recent victory at the 2024 Magnús Ver Magnússon Classic, coupled with world records in stone events, signals a return to top form. With a winning percentage of 25% and a podium percentage of 77.27% across 48 international and national competitions, Kieliszkowski remains a dominant force.
