Despite our recent spate of posts extolling the many and varied benefits of heavy resistance training, I’ve actually been moving away from the weight room for a couple reasons. Foremost is my desire to stay active and as injury-free as possible. While I still wholeheartedly endorse and believe in lifting hard and lifting heavy, at my age I’m starting to realize that the potential for injury – at least for me, personally – is too great to risk spending three days lifting heavy things on a weekly basis. At this point in my life, my motivation is simply different. I’m not really interested in pushing myself to the limit, let alone past the limit (realistically, those days are behind me); I’m instead focusing on maintaining my current performance. It’s almost a Buddhist thing where I’m content with my strength and my body (and have been for a long time now), rather than dissatisfied and constantly striving for more. I also Grok (or “own”) the notion that my diet dictates 80% of my body composition, so I really don’t have to work so hard to maintain muscle mass, strength, power, body fat etc. I’ve touched on this in the past, but a recent email from reader Griffin made me realize a substantial post was in order.
Just because Conventional Wisdom seems to get almost everything wrong when it comes to effective fitness, proper human nutrition, and preventing degenerative diseases, it doesn’t necessarily follow that all official recommendations and prescriptions are faulty. Cigarettes are bad for your health, for example, and drinking and driving actually do not mix. Those are two obvious examples of CW getting it right, and there are definitely a few others, but today, I’m mostly interested in the popular concept of good posture. What is posture? Is “good posture,” as defined by chiropractors, teachers, office ergonomic consultants, drill sergeants, and Grandma (“straighten up, sonny!”), actually good for us? Or have the experts gotten it wrong, once again? Looking around me, if people are listening to the professional advice, it’s bad advice. Slumping, slouching – I see it everywhere, every day, and not just when people are sitting. Can we apply the Primal Blueprint approach to posture and toss it all out?
About 20% of adults have flat feet. A small subset of the population suffers from hereditary flat foot, but most of it is developed. Very few of us are actually born with flat foot. In this post I’ll explore what you can do to avoid flat feet in the first place, and if you already have them whether it is possible to reverse the damage.
Or maybe you don’t. It turns out that sitting in a chair – that time honored tradition we commonly associate with rest, relaxation, and recuperation (don’t forget mind-numbing work, too!) – is actually bad for us. At least, the way we approach sitting is health harmful. The occasional dalliance with a straight-backed office chair probably isn’t a problem, but when we spend most of our waking life sitting (or, even worse, slumping over) in a chair, we invite disaster. Such sedentarism is a real problem, and a recent one. Grok certainly wasn’t bound to a desk. He may have had more off time than we do (if modern hunter-gatherers are any indication), but he didn’t spend it subjecting his body to extended bouts of unnatural contortions. And there’s the other big difference: the way we sit is completely unnatural. Instead of sprawling out, hands behind our heads, legs outstretched, we moderns “relax” in a chair – a piece of furniture with which we have relatively new relations.
