"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.
Research shows that, if anything, physical activity boosts short-term brain function and heightens awareness. And even on days they don’t train — which rules out fatigue as a factor — those who habitually push their bodies tend to confront daily stressors with a stoic demeanor. While the traditional benefits of vigorous exercise — like prevention and treatment of diabetes, heart disease, stroke, hypertension, and osteoporosis — are well known and often reported, the most powerful benefit might be the lesson that my coach imparted to me: In a world where comfort is king, arduous physical activity provides a rare opportunity to practice suffering.
What’s remarkable and encouraging about these studies is that the subjects weren’t exercising at heroic intensities or volumes. They were simply doing something that was physically challenging for them – going from no exercise to some exercise; one need not be an elite athlete or fitness nerd to reap the bulletproofing benefits of exercise.
The truth, cliché as it may sound, is this: When you develop physical fitness, you’re developing life fitness, too."
