DAE love watching survival shows? What do you think you could do to replicate that in every day?

I love shows like American Grit, Special Forces, Alone, Win the Wilderness.

I haven't physically challenged myself in awhile. I am NOT willing to shit in the woods (sorry).

What kinds of things can I do within civilization to copy this sort of physical test?

My ideas:

1. long term fasting

2. go ruck challenge https://www.goruckevents.com/goruck-challenge

3. cold showers

Any other ideas?
