What I need for myself is focused, individual training.
After years of mutual transformation, Israel Adesanya and Auckland's City Kickboxing have parted ways — not in conflict, but in the quiet recognition that what builds us does not always sustain us. The 36-year-old former two-time UFC middleweight champion announced the split publicly on Friday, having already spoken privately with coach Eugene Bareman in May. It is a moment familiar to any long human endeavor: the institution that forged the individual eventually yields to the individual's need to forge himself anew.
- Adesanya, 36 and twice a champion, has reached a crossroads where the training structure that built his career may no longer be the one that extends it.
- The announcement — made on YouTube after a private conversation with coach Eugene Bareman in May — signals a deliberate, if bittersweet, severance from the team-based world he helped create.
- He invoked the definition of insanity to explain his reasoning: repeating the same approach and expecting different outcomes is a trap he is no longer willing to set for himself.
- What he is moving toward is individualized, focused preparation — a more solitary philosophy suited to the specific demands of his career's later stage.
- City Kickboxing, now a globally recognized destination gym partly because of Adesanya's own success, loses its most prominent ambassador at the height of its international reputation.
- Whether this recalibration leads to another title run or simply a more sustainable path forward, the partnership that defined a generation of New Zealand combat sports has formally closed.
Israel Adesanya, the 36-year-old former two-time UFC middleweight champion, has ended his partnership with City Kickboxing — the Auckland gym that shaped his rise to the top of the sport. He made the announcement on his YouTube channel on Friday, though he had already told longtime coach Eugene Bareman of his decision back in May.
The split closes a chapter that defined both men and the institution between them. When Adesanya arrived at City Kickboxing, it was a local gym. Through his championships and global profile, he helped transform it into a world-class destination — something he acknowledged with pride, calling himself one of the main architects of that change.
Still, he framed the departure as necessary rather than painful. Citing the familiar idea that repeating the same approach while expecting different results is its own kind of trap, he said the move was "exactly what I needed" at this point in his career. What he needs now is individualized, focused training — something distinct from the collaborative, team-based environment City Kickboxing provides.
Adesanya was careful to express genuine gratitude, crediting the gym with making him the fighter he became. But gratitude and necessity don't always point in the same direction. At 36, with two championship reigns behind him, he appears to be betting on a more tailored preparation as he navigates the later chapters of his professional life. Whether that bet yields another title or simply a more sustainable path remains an open question.
Israel Adesanya, the 36-year-old former two-time UFC middleweight champion, has ended his partnership with City Kickboxing, the Auckland gym that shaped his rise to the sport's highest level. He made the announcement public on his YouTube channel, Freestylebender, on Friday, though he had already informed his longtime coach Eugene Bareman of the decision back in May.
The split marks the conclusion of a relationship that defined both Adesanya's career and the gym's international reputation. When he arrived at City Kickboxing years earlier, it was a local operation. Through his success—his championships, his technical innovations, his global profile—he helped transform it into a destination gym, a place fighters from around the world now seek out to train. Adesanya acknowledged this mutual elevation explicitly, saying he was proud to have been one of the main architects of that transformation, instrumental in taking the gym to a level where it became known across the sport.
Yet for all that history, Adesanya framed the departure not as a rupture but as a logical next step. He called it bittersweet, but also necessary. "It's the right thing for me, especially where I'm at in my career, it's exactly what I needed," he said in his announcement. He invoked a familiar phrase about insanity—doing the same thing and expecting different results—suggesting that continuing on the same path, with the same training structure, would no longer serve his ambitions.
What he needs now, he explained, is different from what the gym environment provides. He wants focused, individual training—a more personalized, perhaps more isolated approach to his preparation. This signals a shift in how he sees his own development at this stage of his career. At 36, with two championship reigns already behind him, Adesanya appears to be seeking a training philosophy tailored specifically to his current needs rather than the collaborative, team-based model that City Kickboxing represents.
Adesanya was careful to express gratitude. He credited the gym with making him the fighter he became, acknowledging the debt he owes to the environment and the people who trained him there. But gratitude and necessity are not always aligned. Sometimes the thing that built you is no longer the thing you need. His decision to leave, he suggested, was personal—a matter of what serves him best now—and he declined to elaborate further on the specifics.
The move leaves City Kickboxing without its most famous ambassador at a moment when the gym has never been more prominent globally. For Adesanya, it represents a bet on a different kind of preparation as he navigates the later chapters of his professional life. Whether that shift will lead to another championship run or simply a more sustainable way to train remains to be seen. What is clear is that one of combat sports' most significant partnerships has reached its end.

The Hearth Conversation Another angle on the story
Why would a fighter leave the gym that made him a champion? That seems counterintuitive.
Because the thing that built you isn't always the thing you need anymore. At 36, after two title reigns, Adesanya's looking for something different—more personalized, more focused on his specific needs right now.
But City Kickboxing is world-class. Couldn't he just train differently within the same gym?
Maybe. But sometimes the environment itself becomes the constraint. A team gym is built for collaboration, for multiple fighters at different levels. He's saying he needs something more singular, more tailored to where he is.
Does this suggest he's winding down, or gearing up for something?
That's the question nobody can answer yet. It could be either. He might be preparing for one more serious run at the title, or he might be accepting that his championship days are behind him and training accordingly. The move itself doesn't tell you which.
What does it mean for City Kickboxing?
They lose their biggest name, their global calling card. But they've already built something real—other fighters want to train there now because of what Adesanya helped create. That doesn't disappear with him. Though his absence will be felt.
