For a long time, I didn’t appreciate the relationship between physical stamina and cognitive performance, nor did I realize jus how much learning to take on physical challenges can boost your ability to take on mental ones. But I’ve got a whole chapter on the subject in REST.

So I liked this piece on “How Exercise Shapes You, Far Beyond the Gym:”

When I first started training for marathons a little over ten years ago, my coach told me something I’ve never forgotten: that I would need to learn how to be comfortable with being uncomfortable. I didn’t know it at the time, but that skill, cultivated through running, would help me as much, if not more, off the road as it would on it.

It’s not just me, and it’s not just running. Ask anyone whose day regularly includes a hard bike ride, sprints in the pool, a complex problem on the climbing wall, or a progressive powerlifting circuit, and they’ll likely tell you the same: A difficult conversation just doesn’t seem so difficult anymore. A tight deadline not so intimidating. Relationship problems not so problematic….

Exercise isn’t just about helping out your health down the road, and it’s certainly not just about vanity. What you do in the gym (or on the roads, in the ocean, etc.) makes you a better, higher-performing person outside of it.
