Campaigners say groups’ online channels contain white nationalism, fascist imagery and misogynistic language

Concerns about the growth of self-styled fitness clubs organised by the far right have prompted calls for action to counter misogynistic messaging targeted at young men and boys.

Campaigners want the UK government to recognise the danger presented by so-called “active clubs” – a loose movement imported from the US – and use moments such as a review of the school curriculum to challenge their ideology.
