Steel Warriors is a UK charity that melts down knives taken off the streets and recycles them into free outdoor gyms. Through the sport of calisthenics, we show young people that lives can be built on steel, not destroyed by it.

“Steel Warriors is a great charity and trying to turn a negative into a positive.”
Anthony Joshua OBE, Patron and two-time unified heavyweight champion
“Cue the Steel Warriors effect. A three-fold impact, it firstly takes knives off the streets. Secondly, it dissuades impressionable members of the community from being absorbed into gang culture and, thirdly, transforms the area from a potential hotbed for crime into something considerably more community-focused.” Men's Health
