As someone who’s been pushing the seven-foot mark since I was a sophomore in high school, it’s pretty rare for me to run into someone who’s capable of making me feel tiny. However, that’s exactly what happened when I got the chance to sit down and chat with Hafthor Bjornsson, the absolute behemoth of a human being who first made a name for himself as a professional strongman before landing the role of Gregor “The Mountain” Clegane on Game of Thrones.

A few months later, Bjornsson would set a world record for the heaviest deadlift ever completed en route to winning the title of Europe’s Strongest Man for the fifth time. However, after spending a solid decade of his life housing the unreal amount of food he downed on his way to amassing the more than 400 pounds he once boasted on his 6’9″ frame, the big man slimmed down after deciding it was time to pivot to boxing.

Bjornsson has spent over a year preparing for a bout with fellow strongman Eddie Hall, which was originally scheduled to take place on September 18th before the latter succumbed to a gnarly bicep injury. However, his opponent has continued to train while undergoing the insane transformation that’s resulted in Bjornsson dropping over 110 pounds and developing an absurdly ripped physique.

Anyone who’s turned to a new diet and exercise regimen in the hopes of slimming down is likely familiar with the adage “weight loss starts in the kitchen,” and while Bjornsson has checked that box with his revamped diet, he’s also taken a different approach in the gym now that he’s focusing on a new discipline.

The former World’s Strongest Man recently spoke with Insider to shed some light on how he got shredded and specifically focused on what went into developing the impressive six-pack he’s developed as a result of focusing on his core.

You probably won’t be shocked to learn sit-ups played a major role, but your abs might hurt by just reading how many he’s done on his way to defining his, as Bjornsson revealed he’s been doing 300 every single day for more than a year. He did admit to routinely breaking that number up into smaller sets, but also said he’ll occasionally bang them all out in a single go.

Based on the results, he’s doing something right.
