From Chronic Illness to Global Stage: The Resilient Rise of Ben Woolliss

In the high-impact world of professional kickboxing, fighters are accustomed to physical trauma. However, for Grimsby native Ben “The Problem” Woolliss, the most grueling battle wasn’t fought against an opponent in the ring, but against his own body. After years of battling the debilitating effects of Crohn’s disease, Woolliss has transitioned from a state of physical collapse to competing at the pinnacle of ONE Championship.

The Internal War: Living with Crohn’s Disease

For much of his early career, Woolliss was fighting an invisible enemy. He spent five to six years living with Crohn’s disease without a diagnosis, a period he describes as a relentless struggle against an incurable autoimmune condition. Crohn’s disease attacks the digestive tract, often leading to the formation of ulcers, severe anemia, and profound fatigue due to blood loss.

The physical toll was often catastrophic. Woolliss recalls periods where his objective was simply to survive the day. “There were times where the whole objective of the day was to stand up, walk around the room and come back to the sofa,” he shared. During training sessions, the exhaustion was so acute that he would frequently collapse after mere seconds of work. “We’d do 15 seconds on the pads, 20 seconds on the pads. I’d collapse,” he noted, explaining that the lack of iron in his body left him with “severe fatigue.”

Despite the “crushing fatigue” and the physical limitations, Woolliss remained undeterred. Even during his most vulnerable moments—which he described as feeling close to a “coma state”—he maintained a singular focus on recovery and progress, telling himself, “I stood up once today, I can stand up twice tomorrow.”

A Explosive Debut: Taking Down a Legend

Woolliss’s transition to the global stage was nothing short of meteoric. In March, at ONE Fight Night 41, he made his promotional debut under immense pressure. With only nine days’ notice, the Englishman was drafted to face Brazilian knockout specialist John “Hands of Stone” Lineker.

Rather than being intimidated by Lineker’s legendary status, Woolliss utilized the experience of his health struggles to maintain composure. He dismantled the former champion in less than two minutes, utilizing devastating calf kicks to secure a TKO victory. Reflecting on the short notice and the caliber of the opponent, Woolliss stated, “On the outside it can seem extremely daunting, but the positions that I’ve been through in life I feel like they’ve prepared me for these moments because it’s just competition.”

The Next Chapter: ONE Fight Night 43

The momentum from his debut has propelled Woolliss into another high-stakes encounter. He is set to return to action in a bantamweight kickboxing bout against Thai veteran and 17-time world champion Petchtanong Petchfergus. The bout is part of ONE Fight Night 43: Tang vs. Gasanov, emanating from Bangkok’s iconic Lumpinee Stadium.

Facing an opponent with over 400 fights, Woolliss is not looking for an easy path. He has explicitly requested the most challenging matchups available, viewing the opportunity to showcase his skill against elite competition as the ultimate reward for his resilience. “I’ve come into ONE Championship and asked for the biggest fights straight off the bat and they have definitely delivered,” he said.
