Margot Robbie herniated a disc with bumps and blisters in her neck while training for I, Tonya in 2017. Almost a decade after the release of I, Tonya, fans still marvel at Robbie's extraordinary commitment to playing figure skater Tonya Harding. Her stunning transformation not only earned widespread critical praise and an Academy Award nomination for Best Actress but required immense physical sacrifice. She demonstrated the raw dedication behind one of modern Hollywood's most memorable performances.

Margot Robbie's intense physical preparation ultimately caused a painful spinal injury that threatened to disrupt the entire film production.

The relentless physical strain eventually caused a painful herniated disc inside Margot Robbie’s neck early in her preparation for I, Tonya. To authentically capture Tonya Harding's explosive athletic style, Margot Robbie spent 5 months training four hours daily. She remained unaware of the severe damage until production began in Atlanta, where her arms suddenly started going numb.

"There were lots of bumps and bruises, lots of blisters. I herniated a disc in my neck," said Robbie as she spoke to the Daily Star in 2018. Medical evaluations confirmed the neck injury, forcing her to manage chronic pain with routine magnetic resonance imaging scans and cortisone injections. Because executing a triple axel carries extreme injury risks, even elite stunt doubles could not risk performing the move for the film, forcing producer Tom Ackerley to rely on visual effects.

In addition to the gruelling physical toll, Margot Robbie faced immense mental pressure while portraying a real-life figure whose story carried heavy public judgment. To overcome her anxiety and honour the role, she wrote grounding mantras in her script to remind herself that her sole duty was to serve the character.

 "I kept writing, 'It's not about you, get over it. You are a vehicle for this character'," she said to Daily Stars.

The raw physical dedication seen in figure skating movies mirrors the uncompromising drive highlighted across modern sports documentaries.

Cinematic portrayals of athletic grit reflect a broader cultural fascination with intense skating subcultures and personal perseverance. The 2025 ESPN 30 for 30 film Empire Skate explores gritty New York City street culture alongside icons like Tony Hawk. Similarly, Stay on Board: The Leo Baker Story (Netflix documentary) follows a professional athlete navigating high-stakes Olympic pressures. Other acclaimed non-fiction films examine the personal sacrifices.

Tony Hawk: Until the Wheels Fall Off provides an unflinching look at the physical injuries and mental drive of an action sports legend. Meanwhile, the Oscar-nominated Minding the Gap explores deep personal bonds forged through shared athletic passions. These compelling documentary projects prove that audiences remain deeply fascinated by the physical demands and emotional risks of skating sports.

Margot Robbie's celebrated performance in I, Tonya stands as a shining example of that relentless artistic and athletic dedication. Whether on ice rinks or concrete streets, athletes continuously risk severe injury to achieve personal excellence. Robbie's relentless work ethic can be seen again by the USA fans on Amazon Video and Apple TV in 2026.
