Early Life and Sports Beginnings
Hafþór was born in Reykjavík, Iceland, on November 26, 1988. When he was eleven, his family moved to Kópavogur. As a child, he had a lot of energy and found it hard to sit still in class.
He loved sports from a young age. He played soccer and did gymnastics. In eighth grade, he found his true passion: basketball. He also enjoyed playing chess and video games.
Hafþór was tall and thin as a teenager. He became stronger by exercising daily. He did basic moves like push-ups and chin-ups. He also worked on his grandfather's farm in the summers, lifting large natural stones. His height of 205 cm (6 ft 9 in) comes from his tall parents and grandfather. Hafþór has two sisters, Bryndís and Hafdís.

Hafþór started his sports journey as a basketball player. He played as a center and weighed about 105 kg (231 lb). He began playing for the Breiðablik club in Iceland in 2004.
The next year, he moved to FSu Selfoss. But he found out he had been playing with a broken ankle bone and needed surgery. After he got better, he joined KR, a top Icelandic team, in 2006. However, a screw in his ankle broke, and he needed a second surgery. This made him miss the rest of the season.
In the 2007–2008 season, Hafþór returned to FSu Selfoss. He helped his team get promoted to a higher league. But his ankle problems continued. He had to stop playing basketball at age nineteen. This ended his dream of playing in the NBA.
Between 2004 and 2006, Hafþór played 32 games for Iceland's junior national basketball teams. He also played 8 games for the U-18 national team. He won the Nordic championship with the U-16 team in May 2004. He also helped Iceland get promoted in the U16 European Championship. In 2006, he won the Nordic championship again with the U-18 team.

Medal record
|
After his ankle injury, Hafþór started training like a bodybuilder. One day, Magnús Ver Magnússon, a four-time World's Strongest Man champion, saw Hafþór lifting weights. Magnús immediately saw his potential to become a great strongman. This led Hafþór to train with other strongmen like Stefán Sölvi Pétursson.
In 2012, Hafþór reached his heaviest weight ever, 210 kg (463 lb). He was nicknamed Ljónið (the Lion) because he kept getting bigger and stronger.
Iceland's Strongest Man Wins
With new friends and guidance, Hafþór became very good at strongman. He won many strongman contests in Iceland starting in 2009. These included Westfjord's Viking and Iceland's Strongest Viking.
In 2011, Hafþór won his first Iceland's Strongest Man title. This is Iceland's most important strongman competition. He was the ninth Icelander to win it since 1985. He continued his winning streak. In 2024, Hafþór won Iceland's Strongest Man for the eleventh time. This included ten wins in a row from 2011 to 2020.
International Strongman Competitions
The Strongman Champions League gave Hafþór a chance to compete internationally. He competed against the best strongmen in the world. From 2013 to 2015, he competed in many events across different countries. He won eight international titles and several silver and bronze medals.
In January 2015, at the World's Strongest Viking competition in Norway, Hafþór carried a huge log. It was 10-metre-long (33 ft) and weighed 650 kg (1,433 lb). He carried it for five steps, breaking a 1,000-year-old record set by Orm Storolfsson.
Europe's Strongest Man Titles
Hafþór won the 2014 Europe's Strongest Man competition in Leeds. He had placed fifth in 2012 and fourth in 2013. During the 2014 competition, he set a new world record in the Atlas stones event. He famously told a reporter, "I'm the future of strength, and I'm king of the stones!"
He won the title again in 2015. In 2016, he lost the title to Laurence Shahlaei due to a mistake. He won it back in 2017 after a tough battle with Eddie Hall. He won again in 2018 and 2019, becoming a five-time Europe's Strongest Man Champion.
Hafþór has also won other Giants Live events. This makes him the greatest Giants Live champion ever, with nine wins.
World's Strongest Man Victory
Hafþór first competed in World's Strongest Man in 2011, placing sixth. He was one of the youngest finalists ever. He placed third in 2012, 2013, and 2015. He finished second in 2014, 2016, and 2017.
Finally, in 2018, Hafþór became the World's Strongest Man. He won by a good margin over Mateusz Kieliszkowski. He was the third Icelander to win this title.
In 2019, Hafþór tried to defend his title but got an injury. He finished third overall. This gave him the longest continuous streak of finishing on the podium (top three) in World's Strongest Man history, with eight times in a row. Hafþór has also won more vehicle pulls and stone events than anyone else in the competition's history. He has always made it to the finals in all nine of his appearances. In May 2020, Hafþór announced he would not return to World's Strongest Man competitions.
Arnold Strongman Classic Success
Hafþór first gained attention at the Arnold Sports Festival in 2011. He placed second in the amateur competition. This helped him qualify for the Arnold Pro Strongman World Series. He went on to win several Arnold competitions in Brazil, Australia, and South Africa.
The Arnold Strongman Classic is known as the toughest strongman contest. Hafþór first competed in the finals in 2012, placing tenth. But he kept getting better. He placed second in 2017. In 2018, Hafþór won the 2018 Arnold Strongman Classic, beating the champion, Brian Shaw. He also broke the elephant bar deadlift world record, lifting 472 kg (1,041 lb).
Hafþór won the title again in 2019. He improved his elephant bar deadlift record to 474.5 kg (1,046 lb). He won for a third time in 2020. This made him one of only three people to win the Arnold Strongman Classic three times in a row.
After taking a break for boxing and powerlifting, Hafþór returned to the 2024 Arnold Strongman Classic. He lifted 456 kg (1,005 lb) in the deadlift event.

Strongman Legacy
Hafþór won all the major strongman competitions during his career. These include World's Strongest Man, Arnold Strongman Classic, and Europe's Strongest Man. His 30 international wins make him the third most successful strongman ever.
Early in his career, he was known for events that needed stamina and athleticism, like loading races and stone carries. But he kept improving his brute strength for static lifts like deadlifts and squats. By 2018, he was a very well-rounded strongman. Experts say his performance from 2018 to 2020 was the "highest peak performance" of any strongman. During this time, he was almost unbeatable, only losing due to injuries. Hafþór's many wins and over 100 world records have made him one of the greatest strongmen of all time. Many experts believe he is "the strongest man to have ever walked the earth."
