Early Life 

Hafþór Júlíus Björnsson was born in Reykjavík, Iceland.

Hafthor Bjornsson Young

Bjornsson is a descendant of very tall family members. His father stands 6’8″ while his mother is also very tall, and his grandfather even taller than this father at 207 cm (6 ft 12 in). 

Hafthor grew up working on a farm with his grandfather where he worked hard all day. He would have to pick up heavy stones and rocks of which he once jokingly said was the start of his Strongman training. His grandfather 

Reaching a towering height of 6’9″, the future Strongman legend competed in the sport of basketball in his earlier years, playing for the Icelandic junior national teams from 2004-2006.

He was the center for Division I club Breiðablik in 2004 and the very next year, joined FSu Selfoss in Icelandic division I before transferring to another division, Úrvalsdeild powerhouse KR in 2006. The same year, he was part of Iceland’s U-18 National team in Division A of U18 European Championship. 

However, the young and very ambitious athlete would eventually succumb to injuries and had to be sidelined. 

He’d later return to FSu Selfoss but could not compete anymore due to being injured which would force him to retire from basketball at age 20. 

Start of Strongman

Hafthor Bjornsson Teenager To Beast

Fate would lead Hafthor in another direction and little did know he’d become one of the most successful Strongman athletes in the sport’s history. 

“Thor” began his weight training journey at 17-18 years old and being the genetic freak that he is, made incredible progress very quickly. He attributes his hard work and discipline to making such amazing improvements and he was, as he would say himself, obsessed!

While he would have help from coaches, Thor knew it was ultimately up to him to do what it takes to become a champion. 

“You can have the best coach in the world, but that doesn’t make you a champion. You have to work for it yourself.”

Training Regime

Training is much different nowadays for the retired Strongman athlete. When he was competing against the strongest men on Earth, he would have to lift crazy amounts of weight. However, his focus is a lot different now, having been preparing for his boxing fight with Eddie Hall

We’ve included one of his Strongman and boxing workout routines below.

Career and Competition

Thor Bjornsson At Arnold Strongman Classic

Hafthor Bjornsson is one of the greatest strength sports athletes in history and has become an icon in the sport. His accolades in and out of Strongman will be talked about for many years to come, and at only 33 years of age, he may just be getting started. 

In 2008, Thor met four-time World’s Strongest Man winner Magnús Ver Magnússon at his gym Jakaból and the legend saw potential in young Hafthor. It was obvious that he was born for the sport evident by his rapid success, including winning several shows just two years later in 2010, one of which was Strongest Man in Iceland. 

To make it more impressive, he placed second behind future 4x World’s Strongest Man champion Brian Shaw at the Jón Páll Sigmarsson Classic the same year. 

Hafthor competed in his first World’s Strongest Man competition in 2011, where he finished in 6th place. He managed to earn a spot on the podium for the next eight years, winning the World’s Strongest Man title in 2018

The Iceland native was also the first Strongman competitor to win the Arnold Strongman Classic, Europe’s Strongest Man and World’s Strongest Man in the same calendar year (2018). 

Thor suffered an injury during the 2019 World’s Strongest Man and settled for third place. This would end up being his last competition in the sport before announcing his retirement in 2020.

Thor Vs. The Beast Boxing Match 

Thor Hall Fight

Hafthor “Thor” Bjornsson and Eddie “The Beast Hall recently went head to head in one of the most highly anticipated boxing spectacles on Saturday, March 19, 2022, inside the Dubai Duty-Free Tennis Stadium, UAE. 

Read full details on the bout here.

The former Strongman rivals, both who won the Strongest Man competition (Hall won in 2017 and Bjornsson won in 2018) developed bad blood through a series of back and forth stemming from drama during their competitive days. 

The bout between these two behemoths was originally scheduled to take place in September 2021, however, Hall had to pull out due to an injury of which the event was postponed.

Thor ended up winning the bout against his foe via unanimous decision (57-54, 57-54, 57-54).

Eddie Hall is hoping for a rematch now which could be possible sometime in the future.

Boxing Record and Future

Prior to signing the contract for his bout against Eddie Hall, Thor had no boxing experience or training. While he won’t be getting in the ring with Tyson Fury anytime soon (or ever), The behemoth has made leaps and bounds regarding his boxing skills. 

He shed over 100 lbs and took on a whole new ripped look in preparation for the battle with 2017 World’s Strongest Man Eddie “The Beast” Hall. 

He faced Pro boxer Steven Ward in an exhibition match that ended in a draw, took on Simon Vallily and got dropped (draw), defeated armwrestling legend Devon Larratt via TKO and beat Eddie Hall by unanimous decision. 

In a recent Q&A with his wife Kelsey, Thor said he wants to continue boxing and after his win against foe Eddie Hall, he must have all the confidence in the world right now. We’re excited to see how he progresses in the ring and who he’ll face next. 

Personal Life

Hafthor With Wife Kelsey Henson And Son

Hafthor was in a relationship with Thelma Björk Steimann, who he has a daughter (Theresa Lif) with. He also dated Andrea Sif Jónsdóttir until 2017. 

Bjornsson married his current wife Kelsey Henson in 2018. They met in 2017 when Hafthor visited the bar Kelsey worked at in Alberta, Canada while he was in town for a Strongman event. The couple quickly received lots of attention for their massive height difference; Thor stands 6’9″ tall while Kelsey is just 157cm or 5’2″. 

On Saturday, 26, 2020, Hafthor and Kelsey welcomed their first child together, a baby boy who they named Stormur Magni Hafþórsson. The couple plans to have another child at some point. 

Thor can speak five languages: Swedish, Norwegian, Icelandic, English and French. He also has many tattoos related to his viking heritage and also has a tattoo of Jón Páll Sigmarsson, the first man in history to win the World’s Strongest Man competition. 

Facing challenges much harder than Strongman competition 

The Icelandic former Strongman has talked about going through extremely challenging times. In a 2019 interview, he explained not having seen or been able to hug his daughter in three years.

“That’s the hardest thing I’ve gone through,” he explained while very emotional. “And The hardest thing is there’s nothing I can do. Of course, if I could I would go now and see her. But sometimes you’re put into different positions but that’s life, it’s unfair.”

Hafthor said that she motivates him to be better and is probably the reason he won the World’s Strongest Man. At the time of the interview, he explained that he’s doing everything in his power to see her despite the unfortunate circumstances. 

Hafthor Bjornsson admits that success can mean many things and no one could argue with this. While achievements, money, and status are all a form of success, Thor also does what he does for his family. 

“When I’m working hard in the gym, I don’t want to let them down I want to make them proud, that’s my biggest motivation.”

Bell’s Palsy 

In 2017, Bjornsson was diagnosed with Bell’s Palsy, a type of paralysis that typically affects one side of the face. It’s very noticeable in the person who has it because the symptoms include twitching, inability to move that side of the face, and weakness. 

Endeavors and Social Media

Despite having such a busy schedule, Thor makes sure to stay active on social media, although he admits it’s hard to do.

He currently has 600k YouTube subscribers and tries to post content regularly to keep his fans updated with everything going on in his life. The multi-talented athlete also has 3.9 million Instagram followers

Hafthor also has a clothing brand, Thor’s Power apparel. He’s also sponsored by companies Reign, Transparent Labs and The Beard Struggle. He’s always involved with business opportunities and is focused on growing his brand. 

Acting Work

Hafthor Bjornsson has also found some success as an actor. 

The biggest acting gig of his career was playing the role of Gregor “The Mountain” Clegane in the HBO series Game of Thrones for five seasons. 

But he’s no stranger to the camera, in general, having been in the spotlight many times, and in many documentaries.
