Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...Tell Me More
Yesterday, I explored the malleable meaning of fitness, including how our ideas of fitness (both reproductive and physical alike) have drastically changed over history. What began as a reliable indicator of a person’s ability to survive and provide for his or her family or tribe has lost its urgency, and becoming fit in the modern world is now a choice, rather than a necessity for reproductive survival.
Or is it?
Putting aside the potential long-term health and longevity benefits conferred by optimum human fitness (to be discussed later), there are still certain timeless, universal advantages to being fit. And no, I’m not talking about stuff like tool making, hunting, interpersonal combat, hard physical labor – all classic human activities that undoubtedly see a boost when the actor is fit, but they aren’t exactly ubiquitous in 2009. I’m talking about those fight-or-flight moments, those instances where time slows down and you’ve got to act – NOW – or risk probable death. Grok faced these moments, probably on a regular basis, and it was his level of physical fitness that determined whether he’d escape unscathed or lose his life. We face these moments, too, though perhaps not as regularly as Grok (though this depends on our station in life), and the survival mechanisms are exactly the same.
You can’t always reach for your cell phone and call the authorities, and sometimes you just can’t wait to be rescued. In these situations, the abilities to maneuver your body with precision, manipulate/lift/push/pull your own bodyweight without tiring too quickly, jump high and far enough to clear a few feet, swim for a few hundred meters, and maintain top running speed for a couple hundred meters are crucial for survival.
These are, of course, extreme examples. Most of them are unlikely to ever befall us, and I seriously hope they never do. But that doesn’t diminish the fact that these have happened, do happen, and will probably happen again, or that they negatively impact our survival – our reproductive fitness. One commenter on yesterday’s post asked about competency in fitness – “What’s ‘competent’ to mean these days, anyway?” – and I think the ability to save your own life in an immediate (however rare) crisis should be the absolute baseline for general competency. After all, what’s more truly indicative of one’s fitness (the ability to survive and reproduce) than being able to call upon said fitness to extricate oneself from a dangerous situation. That should be the absolute minimum.
So, I count manipulating your own weight (including pulling, climbing, pushing), supporting someone else’s weight while walking, swimming, and sprinting as the fundamental abilities any competently fit person interested in surviving dangerous situations should possess. I’m sure I’m missing at least a few more, though, so I’d love to hear from readers: what other physical abilities do you consider crucial for survival, especially in this modern world?
Now that I’ve established a tentative baseline standard for human fitness, tomorrow I’ll be exploring the other ways we can classify and compartmentalize effective, proper physical fitness. Is there an ultimate standard for optimum fitness? Check back tomorrow!
