Chalk Talk: Fundamentals from the CrossFit Journal & Beyond: The Sickness-Wellness-Fitness Continuum
One of the most iconic ideas in the roots of CrossFit is the Sickness-Wellness-Fitness Continuum. On one end: sickness. On the other: fitness. And right in the middle, where most of us think we live: wellness.
We tend to think of sick and healthy as a light switch, you're one or the other. But they're not two different categories. They're the same line, and every measurable marker of your health, blood pressure, body fat, cholesterol, bone density, resting heart rate, even mental health, lives somewhere on it.
What makes fitness different from wellness isn't just that your numbers look better. It's that you've put distance between yourself and the sick end of that line.
When you're fit, you don't go straight from fine to sick. Something has to bring you all the way back through wellness first before sickness can even reach you. That gap is what you've built. The more fit you are, the more runway you have. As the CrossFit graphic puts it: "Markers toward fitness provide a long-term buffer against sickness, disease, and decrepitude."
Life happens to all of us. A hard year, a diagnosis, something that comes out of nowhere. We can't control that. But we can control how much margin we walk into it with.
It is fun to train for a goal. A competition, a new PR, a new skill. It is also a nice benefit that we can give ourselves the best possible chance in the event of a health challenge. It's like an emergency fund for your health!
