I'm not even sure I'm kidding, htere are definite and steep class, racial, and cultural elements to outdoor recreation. Fuck, eugenics elements.
The cult of the body is reactionary and bourgeois. All bodily activity should be based on care, not performance. Only the privileged can devote time vainly shaping their bodies because they are jealous of workers who have to develop their muscles for survival. Pushing people to do sports rather than cultivating their minds is capital's strategy to preserve itself. Strong bodies with weak minds make perfect reactionaries, weak bodies with strong minds can convince the strong bodies to become revolutionary instead.
Health is precious though, and exercising is good to fight depression, so listen to Mao and go make your blood circulate. Performance bad, care good
