Women’s Fitness: Should It Change with Age?

Generally speaking, the basic Primal Blueprint for fitness and physical activity applies equally to men and women of all ages. Lifting heavy things works in everyone. Sprinting is a fantastic way—for anyone who’s able—to compress workouts and improve training efficiency. Improving one’s aerobic capacity through easy cardio doesn’t discriminate between the sexes. And everyone should walk, hike, garden, and perform as much low level physical activity as possible. These basic foundations—the 30,000 foot view of fitness—don’t really change across age or sex.

But the details do, especially for women.

Primal Starter: Living Purposefully

Living life on your own terms isn’t just a quaint turn of phrase. It has huge effects on your health. A large body of research shows that the less control you think you have over your life, the higher your mortality risk. That persists even when you control for other health variables and biomarkers. It’s even true for animals. Self-agency—or even the illusion of it—appears to be a requirement for healthy, happy aging.

And unlike some of the characteristics shared by centenarians, like good genes, control is malleable. You can’t change the structure of your DNA. You can, however, wrest control over your own life. Despite whatever challenges present themselves, you get to decide what purpose you contribute to each day.

Slow Moving Training: Yoga

I like intensity when I train. Lifting heavy, running sprints, playing Ultimate Frisbee. I keep it brief, and the foundation is always a lot of slow movement throughout the day—easy runs, long walks or hikes, rarely sitting—but I go hard when I “work out.”

What if you were to go slow, on purpose?

Entire schools of physical culture are founded upon slow, deliberate movements. They squash momentum and lambast rapidity. They’re difficult in a different way. They require patience and fortitude.

Take yoga.

Primal Reflection Point: How Are You Playing?

“Insufficient play is another major disconnect in modern life, causing reduced productivity, increased stress, and accelerated aging. Stuart Brown, author of Play: How It Shapes the Brain, Opens the Imagination, and Invigorates the Soul and one of the world’s leading experts on play, calls play a ‘profound biologic process.’ He explains that play, across the span of a lifetime, promotes the development and maintenance of a ‘cognitively fluid mind.’

“Cognitive fluidity—being able to go with the flow, think outside the box, process what-if scenarios, and react quickly and effectively to changes in our environment—is believed by anthropologists to represent one of the most profound breakthroughs in human evolution. This breakthrough in brain function, probably emerging 60,000 years ago, meant that humans’ brains could link knowledge from different domains. The way humans understood and approached the world became both more flexible and more expansive. This enabled more creative use of technology, better transfer of knowledge between generations, and a resultant spike in human longevity. Cognitive fluidity is still essential today, helping us adapt and thrive in a complex, high-tech society. When we get stuck in patterns of overwork and overstress, we lose that important connection with our creative, intuitive, playful selves. Our work suffers and so does our happiness.”

What Collagen Does For Performance

I’ve always been a student of performance—in my athletic days and now. Whether it’s nutritional intake, training strategies, or supplement choices, this is where science comes to life for me. Over the years, I made this interest work for my fitness performance and now for my optimal health. It’s not about “hacking” the body’s functioning but understanding it from the ground floor up. This knowledge helps me live and age through life more on my own terms, which is exactly the way I like it.

Why Aren’t We Talking About the Cognitive Health Crisis?

If you look at the latest stats, you might assume there’s no cognitive health crisis. The overall number of dementia cases are going up, but that’s because the aging population is growing. Older folks are living longer than ever before, so there are more people around who can develop dementia. Dementia and Alzheimer’s rates are dropping in the Western world. Politicians, those archetypical paragons of cognitive aptitude, are hanging around in office longer than ever. Technology, science, and other fields that require large amounts of cognitive ability are progressing.

But broad trends and large numbers are just statistics. However reassuring they are to public policy analysts, they mean nothing to the individual suffering from cognitive decline. They’re too abstract. Your grandpa no longer knowing who you are? That’s real. You, personally, don’t want to lose your cognitive abilities as you age. You, personally, don’t want to see the people you love get Alzheimer’s. Individual cases matter to those individuals and their loved ones. And it’s still happening more than it should.

The Insulin-Illness Connection

Most discussion of chronically-elevated insulin levels (hyperinsulinemia) and insulin resistance revolves around their relationship to bodyweight. This is unsurprising. Bodyweight’s what “sells tickets.” It’s why most people get interested in diet, health, fitness, and nutrition—to lose weight or avoid gaining it.

But improving insulin sensitivity and reducing fasting insulin levels have major ramifications for your health, longevity, and resistance to disease. And it’s not just because “weight gain is unhealthy.” Insulin itself, in excess, exerts seriously damaging effects. Today, I want to impress upon you the importance of controlling your insulin response by laying out some of the health problems that stem from not controlling it.

Dear Mark: Gender and Retirement Mortality, Muscle-Sparing Keto, Freezing Keto Recipes, Net Carbs, and Carb Timing

For today’s edition of Dear Mark, I’m answering 5 questions from readers. First, are there differential mortality effects of mortality on men and women? What role do social networks play? Second, is ketosis muscle-sparing? Yes, and here’s why. Third, which of the recipes in Keto Reset can be made ahead of time and frozen? We’ve got some busy parents here, after all. For the fourth question, I clarify my stance on net carbs and whether or not to count vegetables. And last, I explain how is is not necessarily ought.

7 Subjective Longevity Markers to Track (and Fix)

A few weeks ago, I went over 7 of the most important longevity biomarkers to track. Today, I’m shifting gears a bit. The theme remains longevity markers, but the markers I’ll discuss today are subjective, logistical, and psychological ones. A couple involve physical sense but you can’t measure these with a blood draw or a lab scan. The only way to assess your standing is through some genuine self-experiment and honest soul-searching. Or by, in one case, running a mile.

So, as you read through today’s list, keep that in mind. Where do you stand—truly? Do any of these apply to you? Number of years aside, what do you really want your longevity gains to look like, feel like? What changes are you willing to commit to now that will make this a more probable reality—to live longer and live more while doing it? Here are a few markers to start with.

Let’s have at it….

7 Longevity Biomarkers to Track

Last year, I wrote about 10 of the most interesting predictors of longevity. Many of them were subjective, but, as we all know, the objective physiological processes that occur in the human body also predict how long we live. Luckily, we can measure most of them. Some are standard at doctor’s checkups. Some require more involved (and expensive) testing. Some you can complete yourself at home with simple household objects.

But if you care at all about how well you’re doing in the longevity game, it’s worth paying attention to some of them.
