How a UFC heavyweight champion turns fear into fuel

Aspinall insists he is “scared to fight everybody,” including Jon Jones, and argues that any fighter who says otherwise is lying or foolish. He reframed fear from something to suppress into a fuel source: like a parent lifting a wardrobe off a child, fear unlocks capabilities that don’t appear in normal conditions. By accepting and “bathing in” fear instead of fighting it, he turns anxiety into heightened focus and performance under the lights.

He estimates fight preparation in the gym is roughly 80% physical and 20% mental, but on fight night those ratios flip to 80% mental. Yet most fighters barely train the mind. Aspinall closes this gap with hypnotherapy, visualization, written affirmations and deliberate daydreaming of walkouts and fight scenarios. By the time he steps into the octagon, he’s “already walked out 10,000 times” in his head, making the environment feel familiar instead of overwhelming.

Borrowing a strategy from Georges St‑Pierre, Aspinall consciously acts calm—head up, shoulders back, smiling—on fight day, even when he’s terrified. He keeps this composure walking to the cage and standing opposite opponents, despite intrusive thoughts about being knocked unconscious in front of millions. Over time, he finds his mind follows his body’s lead, shifting from panic toward genuine relaxation and confidence.

Aspinall’s path to a six‑figure payday took over 20 years of training from age eight to 30, with early pro fights paying as little as £200. He emphasizes that “it takes years to become an overnight success” and that most fighters he’s known never make more than around £5,000 per bout. Injuries, canceled fights, and needing to borrow money for nappies nearly broke him, but he credits sheer consistency and refusing to quit—often pushed by his dad and partner—as the real differentiator.

His catastrophic knee injury at the O2—blowing out 15 seconds into a title eliminator at home—was both his professional low point and a turning point. Immobilized for months, he finally had time to assess his life: poor diet, suboptimal training, and “toxic people” in his circle. He rebuilt everything: lifestyle, environment, physique, and mindset, and considers the post‑injury version of himself “a completely different person” and a far better athlete and man.
