Third-year competitor at the Arnold Classic
Hafthor began competing in strongman after an injury to his ankle ended his basketball career. In his first contest, with no real training, Hafthor won one event and made an Icelandic record in stone carrying. After this auspicious beginning, Hafthor was hooked and began training solely for strongman competitions. Since 2009, he has won seven competitions.
