50 years of excellence
Forging world champions, elite amateurs, and fierce competitors in East London since 1976.
The rooms changed, from a church hall in Forest Gate to the arches in Bethnal Green. The standard did not.
Muhammad Ali's brother is a patron of the gym.

The pedigree & the roots
In 1976 Bill Judd opened KO in a church hall in Forest Gate. The room was small. The idea was not: a gym that would stay, and a standard that would not slip.
The next home was the Lonsdale gym on Carnaby Street. The early squads shared those rounds with boxing greats passing through London, sparring with Honeyghan and Witherspoon.

The Tottenham era
The gym then settled at Tottenham Community Sports Centre and stayed for two decades, through to 2020. The sessions were long, the bags were honest, and the work ethic did not bend.
Willie Bassaga trained and fought out of KO there. A world-class Muay Thai fighter from France, Bill called him an absolute beast, and he beat Winston Fraser. In 2012 the Ali family visited the amateur team, Arches ABC.

The permanent home
In 2020 KO took a permanent home at 187 Bancroft Road, under the railway arches in Bethnal Green, steps from York Hall.
The floor is built for the work that happens there: 3 professional rings and 16 heavy bags, with the rest of the gym set around them.
