Hafþór Júlíus Björnsson, widely recognized for his portrayal of the towering Gregor 'The Mountain' Clegane on HBO's Game of Thrones, has stunned fans with a remarkable physical transformation. The Icelandic actor and former strongman athlete revealed on Instagram that he has shed an astounding 110 pounds over the past year, dropping from 205 kilograms (approximately 451 pounds) to 155 kilograms (about 341 pounds). His post featured before-and-after photographs that highlight the dramatic changes in his physique, sparking widespread attention and admiration across social media.
Björnsson's journey from elite strongman to slimmer, more agile version of himself is a testament to his discipline and adaptability. Standing at 6 feet 9 inches (2.06 meters), he has long been one of the most imposing figures in both sports and entertainment. His role on Game of Thrones capitalized on his immense size and strength, making him a fan favorite in the iconic series that concluded in 2019. However, after years of intense competition and maintaining an enormous body mass, Björnsson decided it was time for a change.
In his Instagram caption, Björnsson wrote simply, 'From 205kg to 155kg,' accompanied by images showing a visibly leaner frame. The transformation is not just about aesthetics; it represents a fundamental shift in his lifestyle priorities. After winning Iceland's Strongest Man title for the 10th consecutive year in 2020, the 31-year-old announced his retirement from competitive strongman. 'Great way to finish my strongman career. Now a different journey starts and I'm super excited,' he posted at the time. He emphasized that his focus was now on being healthy for his family, particularly his wife Kelsey Henson and their newborn son, born in September 2020.
Björnsson's strongman career was legendary. He set world records in events like the deadlift, where he famously lifted 501 kilograms (1,104 pounds) in 2020, breaking the previous record held by Eddie Hall. He also competed in the World's Strongest Man competition multiple times, finishing as runner-up in 2014, 2015, and 2017, and winning the title in 2018. His diet during his competitive years involved consuming up to 10,000 calories daily, often including large quantities of meat, eggs, and supplements to maintain his massive size. In stark contrast, his current weight loss regimen required a completely different nutritional approach, focusing on lower calorie intake and more balanced macronutrients.
The actor's decision to slim down was influenced by his desire to be more present and active with his growing family. He shares a daughter, Theresa Líf, with his ex-girlfriend Thelma Björk Steimann, and welcomed a son with Henson in 2020. The birth of his son was a transformative experience for Björnsson. Henson described the delivery as 'the most powerful, life changing, empowering thing' she had ever done, and Björnsson echoed the sentiment, noting the joy of introducing his newborn to his older sister. The couple married in October 2018 in a ceremony in Iceland, and Björnsson often shares glimpses of their family life on social media.
Beyond the physical changes, Björnsson's transformation has also included a shift in his public persona. While he remains a symbol of strength and power, his openness about prioritizing health and family over competition has resonated with many followers. He has also ventured into acting beyond Game of Thrones, appearing in films such as The Northman (2022) where he played a Viking warrior. His lighter build may open up new roles that require more agility and range, moving beyond the 'strongman' typecast.
To achieve his weight loss, Björnsson worked with a team of nutritionists and trainers, adopting a structured exercise program that includes cardio, weightlifting (with lower weights than his peak), and flexibility training. He has also been transparent about the challenges of such a dramatic transformation, including the emotional and physical demands of losing muscle mass. Nevertheless, his determination has paid off, and he continues to document his progress online, inspiring others who seek to make major lifestyle changes.
The impact of Björnsson's transformation extends beyond his personal life. It highlights the evolving conversation around body image and health in the entertainment industry. For decades, actors and athletes have felt pressured to maintain extreme physiques for roles or competition. Björnsson's choice to slim down after achieving his strongman goals demonstrates that health is not a one-size-fits-all concept, and that even the strongest individuals can benefit from reassessing their priorities.
As of early 2025, Björnsson continues to update fans on his journey, often sharing workout videos and meal prep tips. His Instagram account has become a hub for fitness enthusiasts and Game of Thrones fans alike. While he has not ruled out a return to strongman competition in the future, his current focus remains on his family and his evolving career. The story of Hafþór Júlíus Björnsson is one of reinvention—a man who conquered the world of strength sports, became a pop culture icon, and now embraces a new chapter defined by balance, family, and personal well-being.
