Former fighter now eats every two hours to become a heavily tattooed powerlifter who has gone viral with her bench presses and squat sessions
A once lean, mean, fighting machine has put her dieting days behind her to become a 25-stone powerhouse who eats every two hours.
Jackie Koorn was a disciplined kickboxer weighing just 11 stone (154lbs/70kg), and never imagined the giant change she would make to her body. The 35-year-old Dutch strength athlete now weighs more than twice that at 25 stone (350lbs/159kg) and is rewriting the rules of female athleticism as Jackie SheHulk.
Koorn is no stranger to pushing her body to extremes, having spent over a decade competing as a professional kickboxer, where maintaining a lean physique through strict dieting and weight control was a constant requirement.
When the Covid pandemic brought combat sports to a halt, Koorn found herself at a turning point and decided to shift her focus from achieving leanness to building strength and power.
“I stopped dieting and stopped trying to be small,” she said. “I wanted to see what my body was capable of if I let it grow.”
This pivotal decision marked the beginning of one of the most dramatic physical transformations in the history of strength sports. Over the course of just a few years, Koorn transitioned from kickboxing to powerlifting, progressively bulking up with a singular focus on raw strength.
Koorn eats every two hours, consuming roughly 3,000 calories a day to support muscle growth and recovery. Her daily intake includes eight to 10 eggs, chicken, cottage cheese, granola, and spinach, alongside protein shakes, creatine, and vitamins. Dieting, she claims, is firmly behind her.
“I spent years being controlled by food limits. Now food is fuel.”
As her weight rapidly increased, so did the impressive numbers she achieved in the gym. Now standing at 5ft 7in and weighing 14 stone more than she used to, Koorn dedicates hours each day to intense training sessions, consistently lifting weights that leave onlookers and veteran gym enthusiasts in awe.
Her bench presses, leg presses, and squat sessions have repeatedly gone viral, gaining a devoted following across Europe, the US, and the Middle East. She has built her reputation on a straightforward message: strength does not have a ‘correct’ body type.
Whilst numerous female powerlifters strive for ultra-defined, vascular physiques, Koorn has deliberately taken the opposite approach. She describes her body as big, curvy, and powerful, insisting those qualities are not mutually exclusive.
According to Koorn, doctors often anticipate discovering serious health issues when they see her weight. However, medical tests have consistently surprised them.
“They judge the scale before they judge the results,” she states. “Once they actually look at my markers, they don’t know what to say.”
Outside the gym, Koorn runs her own security business, a job she says suits both her stature and her mindset. A conventional 9-to-5 office role, she admits, was never a realistic option.
With extensive tattoos covering her body, Koorn’s unconventional appearance often sparks intrigue. Sporting tattoos that cover her legs, arms, neck and back, multiple facial piercings and biceps measuring around 25 inches, Koorn acknowledges she can appear daunting at first sight.
“People don’t know how to place someone like me,” she says.
However, those who get to know her describe her as warm, sociable and quick to chuckle. This contrast has been a part of her life since her early years. Brought up on a farm as one of six siblings, Koorn was always physically strong and fiercely protective. She remembers standing up to bullies, including those who targeted her brothers, long before she ever set foot in a gym.
Support from her family has been instrumental in her journey. Her mother, who passed away two years ago, supported her unconventional path with one stipulation: remain strong so you can take on the world.
“She wanted me strong enough to survive the world,” Koorn shared.
Fashion, however, continues to be a daily struggle. With arms and thighs much larger than standard sizes cater for, finding dresses is nearly impossible. Most days, she dons oversized bodybuilding attire designed more for comfort than style.
Her love life has also been complicated by her fame. Whilst Koorn confirms she’s in a relationship, she feels social media attention has skewed how people perceive her. She insists marriage isn’t a priority.
“People fall in love with the image,” she observes. “Not the person behind it.”
Online, Koorn has leveraged her image into a platform. Her Instagram account chronicles her training, competitions and outspoken views on body positivity, whilst her OnlyFans page offers exclusive content to subscribers. She has gained widespread recognition, becoming a familiar figure in the world of strength culture, extending far beyond conventional sporting communities.
Her newfound fame has created fresh opportunities. Koorn is gearing up for wrestling appearances in the Netherlands and has her sights set on performing on international stages. Moreover, her increased visibility has led to acting roles, with recent parts casting her as authoritative, imposing characters.
However, not all health professionals have been supportive. Given her family history of heart disease, Koorn has been repeatedly cautioned about her weight. She remembers challenging doctors to run tests before making judgments about her health. When the results showed no abnormalities, she felt vindicated.
“I don’t want people deciding my health by looking at me,” she asserts.
Now, Koorn is setting her sights higher than ever before. She is preparing for a campaign that includes a bid for World’s Strongest Woman and an official Guinness World Record attempt.
“This isn’t about shocking people,” she explains. “It’s about demonstrating that strength, health, and excellence come in many forms.”
