Gardening?
Till the soil like your great grandfather did. Purchase from small local producers that you know personally. We should grow our own food, get outside more, and not rely on commercial food producers. Over specialization creates a society without purpose for many and too much interdependence. The countryside would remain unaffected in the long run if a future collapse occurs. In cities people are concentrated like ants and living like parasites. You do not want to be a part of it. There’s a reason liberals are concentrated in these shitholes.

It is such values and societal composition that will survive a collapse and reclaim what is left once the dust has settled.
Furthermore, get a punching bag and some dumbbells, go running/sprinting A LOT. Ideally you should go to the gym asap but if you’re insanely out of shape those are the 3 basic stuff you should start doing for home exercise. Also improve your posture, put the monitor on a stand. Don’t sit for hours on end.

We are constantly stimulated by technology. This is unnatural since we used to be able to just sit for hours and reflect, now we get anxious if there is no internet connection. I have a garden I go sit in during the late afternoon and just gaze out on the nearby mountains. Really healthy and fulfilling.
The only "good" things modern society has brought involves making life painstakingly easy and near meaningless. You don’t want to be dependent on the state once post-industrial society hits and we become unproductive slaves for our monthly food ration.
