I hate working out, and never once in all the years I went to the gym did I feel "good" afterwards. Lost almost as much weight as my current total weight, though (still fat lol)
The last year I decided I'm going back to the gym, eating better, and going on more rigorous walks with my dogs.
I decided there's a very real chance I might have to help some friends and neighbors escape the country in my lifetime, so I should be prepared to do so.
if I can't lift, push, pull, run, hike, climb, and generally do things a person running from modern nazis might be required to do, then I'm not much help beyond a stock up on food and ammo.
A healthy breakfast is an important part of fighting fascism.
