At age 22, Mateusz Kieliszkowski made history by being the youngest Strongman competitor in Arnold Classic History. Now 25 years-old, he is no longer seen as merely "the future" of his sport. The 2018 World's Strongest Man runner-up finished 4th at last year’s event in Columbus, but his record-breaking 410 LB stone-to-shoulder lift left little doubt that he was ready to push the likes of Thor and Shaw to the limit.
