> Not wrestling specifically, but you certainly wouldn't be the first to feel a sort of alienation from... I don't know: call it physicality. There's a general sort of malaise you can see present in the US at least, it's why (or possibly because of) we see so much shit marketed to us via faux authenticity.
I used to wonder why people would talk about running in language reminiscent of religion and addiction, until I started feeling the malaise you're describing strongly enough. Unrelatedly, I left my job around the same time (this was about a year ago) and lost the use of their onsite gyms, and started running for the first time since college.
Something was different between my college runs and these newer runs. In college I would bang out 2 or 3 somewhat tedious miles and come home feeling nothing more than satisfied that I had done my required amount of physical activity. I'm not 18 anymore so I've had to be careful about stretching and warming up, but with these new runs, I was up to ten miles within a week and a half. "Getting exercise because it's healthy" is almost incidental to the reason I run now, which has a lot more to do with the feeling of pushing myself as hard and as long as you can.
It's a pretty potent antidote to the general feeling of malaise; it seems that something hardwired pretty deeply in us considers difficult physical activity as worthwhile in and of itself. I'm sure there's more to it (the agrarian-utopianist/yearning for authentic experiences that you're describing), but hard physical activity alone gets you some of the way there, in the same way that you can access some of the surface benefits of meditation without delving into all of its traditional philosophical baggage.
