“Unknown and unknowable” was the theme/tagline of the 2009 CrossFit games, and CrossFit itself deals exclusively with general physical preparedness and aptitude with functional movements.
A workout of the day can address that unknown and unknowable part well; even if you read your box’s website before showing up each day, something new and challenging will be put in front of you. You may do something well, you may do something terribly, and you’ll probably be put out of your comfort zone. But it’s still sanitized, safe, and it is just training. Delight should be found in those rare opportunities when real challenges meet you, where your health and life may depend on what you do, and you need to solve a problem by thinking and moving quickly.
There are places to find these challenges. For me, I recently found one in a three-day backpacking trip out in the Sierra National Forest. This was a genuine, though introductory, taste of the sport. We carried among us provisions and gear for nine people, and ventured out into the barely tamed wilderness of the forest.
Strap 20 or 30 pounds on your back, and ascend and descend more than a thousand feet over the course of around 15 miles. You might have to climb to get out of a valley, or descend to find water. Your life may depend on you moving in a certain direction.
With weight on your back, cross a stream. Do so without getting wet, since your life may depend on your feet, clothes, and sleeping bag being dry when the sun goes down and the temperature drops. Cross muddy trails. Cross boulder-strewn mountain faces. Walk across snow.
This is the unknown, the set of challenges you will face out in the wild. You’ll quickly discover your strengths and weaknesses, and if you’re smart, you’ll try overcoming those weaknesses by adjusting technique, and thinking clearer about how you move.
What am I good at? I turned out to be pretty fit right now, and could climb with weight on my back, at a high altitude, without difficulty. What am I bad at? Coming back down again — terrific strain on my feet, knees, and back. But I can cross streams balanced on logs or rocks, can cross patches of snow with few slips.
