Your Bones Peaked at 30. Nobody Checked.
It’s 1987. I’m eight years old, standing on my grandma’s king-size bed.
My cousins are with me. One pretends to be knocked out on the pillows. Another acts as the referee, counting to three as seriously as only a second-grader can. The bedframe is solid oak, built to outlast its owners. We ignore that. All that matters to us is WWF wrestling.
This was the golden age: Hulk Hogan, Andre the Giant, “Macho Man” Randy Savage, Roddy Piper, Ted DiBiase, Ultimate Warrior, Jake “The Snake” Roberts. To us, these wrestlers were heroes. On Saturday afternoons at grandma’s, her bedroom became Madison Square Garden, and we imagined ourselves as all of them.
I’m on the headboard. The move: diving elbow drop. If you know, you know. If not, just picture a kid launching himself off furniture, convinced physics will play along.
Physics does not play along.
I miss the mattress and land on the bedframe instead. My collarbone against the oak. There’s no contest.
The snap is quiet. The pain isn’t even that bad. The real problem is the next six weeks. Clavicle bandage. Figure-8, tight across my back, arms pulled in. Middle of summer. Everyone else is at the lake or the pool. I’m stuck in this thing that, after a few weeks in July heat, starts to smell like it’s alive. By week six, it basically is.
The upside: at school, I’m untouchable. A broken bone in primary school buys you a kind of status you can’t earn any other way.
That was the first break. Not the last. I wrestled for twenty years after that. Not WWF, real wrestling. Olympic freestyle. Nobody’s playing along. Nobody takes a dive. I broke more bones. When your body is the tool and the sport takes what it wants, you pay the price.
But that first break stayed with me, like a first crush. Vivid, a little ridiculous, and unforgettable.
The bones in that eight-year-old body were still getting stronger. They’d keep building for another twenty years or so, peaking somewhere around my late twenties [5][6]. Then they’d start quietly falling apart. And nobody would mention that either.
Bones don’t just sit there. They peak. Then they decline. Without symptoms. Without warnings. And almost nobody in your life, not your doctor, not your trainer, not the longevity podcasts you listen to between meetings, is talking about it until something snaps.
The Scan You’ve Never Had
With my history, you’d think I’d have checked if my bones are still holding up.
I haven’t. Never had a DEXA scan. Not once.
Have you?
The US Preventive Services Task Force recommends osteoporosis screening for women at 65 [1]. For men, the evidence is, and I’m quoting, “insufficient” even to make a recommendation [1]. The International Society for Clinical Densitometry suggests 70 for men without risk factors [2]. Think about what that means. If you’re a 45-year-old man whose bones peaked 15 years ago, nobody in the medical system is looking. Nobody will look for another 25 years. Your skeleton could be hollowing out right now, and the official medical position is: we don’t know enough to care.
Meanwhile, the same system will screen you for prostate cancer, check your cholesterol annually, and send you reminders about your flu shot. But the scaffolding that holds your entire body upright? Come back when you’re 70. Or when something breaks. Whichever comes first.
You track your performance, check your resting heart rate, know your body fat, and maybe even your VO2 max. But when was the last time you thought about your bones?
I’ll be in the US soon. I’m booking a DEXA scan. They’re everywhere. Most clinics offer them. Cheap, too. One scan. A baseline data point I should have had years ago.
Your Skeleton Is Keeping Score
Most people think bones are like rebar in concrete. Built once, set, done. Not true. Bones are alive. They’re always responding to what you do. They adapt. Leave them alone, and they quietly fade away.
A German surgeon named Julius Wolff figured this out in 1892. His law is simple: bone adapts its structure to the loads placed on it [3]. Tennis players develop measurably thicker bone in their racquet arm. Weightlifters build denser skeletons than runners. Load it or lose it. Harold Frost took this further with what he called the mechanostat model: your skeleton maintains a set point, and loading above that threshold triggers formation while loading below it triggers resorption [4]. Your body is efficient. It will not maintain infrastructure it doesn’t need.
The timeline is sobering. Bone mineral builds up from childhood until about age 25 to 30, when you reach peak bone mass [5][6]. After age 40, both men and women lose about 0.5-1% per year [7][8]. Women lose bone faster after menopause, which I’ll discuss later. Men can start losing bone at some sites as early as their mid-30s, earlier than most people think [7]. By age 50, without intervention, you might have lost 10-20% of your peak bone mass. You may feel the same as you did at 30, but your bones are not the same.
Then there’s the desk. I spent years in consulting, with back-to-back meetings in windowless rooms. I’d sit for twelve hours, fueled by bad coffee and the belief that I was at my best. At 35, I felt invincible, but I wasn’t. Sitting for hours signals to your bones that they don’t need to stay strong [9]. Day after day, your skeleton adapts. It’s been doing this for years.
You’re either building bone or losing it. There’s no middle ground.
“You’re Too Young to Worry About Bone Health”
Osteoporosis lives in our collective imagination as a post-menopausal woman’s condition. And for women, the reality is severe. Women lose up to 20% of their bone density in the five to seven years after menopause [8]. One in two women over 50 will break a bone due to osteoporosis in their lifetime [10]. The screening guidelines reflect this: women get a DEXA recommendation at 65, or earlier if risk factors are present [1]. That part of the system, at least, is working.
What most people don’t know is how badly the system fails men. Twenty percent of men over 50 will experience a fragility fracture [10]. The lifetime risk of fragility fracture in men actually exceeds the risk of prostate cancer [10]. We screen for prostate cancer. We run campaigns for prostate cancer. We don’t screen for the thing that’s statistically more likely to happen.
Male osteoporosis is largely underdiagnosed and undertreated [11]. When it does announce itself, it announces itself as a fracture. And in men, that fracture is more lethal. A man with a hip fracture faces a 7.95-fold increased risk of death in the first three months [12]. One-year mortality sits around 35% for men versus 22% for women [12]. One in three men won’t survive the year after a hip fracture. Current data, not a relic from the 1950s.
The executive profile makes it worse, regardless of gender. Frequent flying, which means reduced vitamin D from living indoors and in airports. Sitting all day, which means mechanical unloading. Meals skipped or eaten between calls, which means protein intake that’s an afterthought. Women in high-performance careers often delay pregnancy or enter perimenopause earlier due to chronic stress, compounding the hormonal drivers of bone loss. Men never get screened because the guidelines say not to bother until 70.
“I’m Active, So I’m Fine”
I hear this often, and I get the reasoning. You move, you exercise, and you’re more active than most people. That should be enough, right?
But it isn’t. Not every type of movement actually builds bone.
A systematic review specifically examined swimming and cycling and found that neither has a positive effect on bone mineral density [13]. Professional cyclists actually lose bone density during training seasons. This is counterintuitive if you think about how fit these people are, but bone doesn’t care about your cardiovascular fitness. Bone cares about mechanical load. And when you’re floating in a pool or spinning on a bike, there’s very little load going through the skeleton.
What does work? The LIFTMOR trial followed postmenopausal women who did high-intensity resistance training: five sets of five reps at greater than 85% of their one-rep max, twice a week, for 30 minutes per session. The result was approximately 4% improvement in lumbar spine bone mineral density compared to a low-intensity control group. Adherence was above 90%. No new fractures [14]. A separate 12-month trial tested the effects of resistance training and jumping on bone mass in physically active men with low bone mass, with a mean age of 44. Both interventions increased bone mineral density in the whole body and lumbar spine [15].
The ranking is straightforward. Heavy lifting is better than impact and jumping. Impact is better than running. Running is better than cycling or swimming. If you’re on your Peloton every morning, that’s great for your heart, but not for your bones. What really helps is lifting heavy weights. Twice a week, for thirty minutes.
Protein is important too. Higher protein intake means fewer hip fractures. Your bones need the right building blocks to get stronger. Without enough protein, calcium, and vitamin D, stressing your bones won’t help. They won’t have what they need to rebuild.
Try This Today
Get a DEXA baseline. If you have any risk factors at all, and that includes fracture history, family history, low body weight, long-term corticosteroid use, chronic sitting, or low vitamin D, don’t wait for a screening recommendation that may never come. Most clinics offer DEXA as an elective for $75-150. “Insufficient evidence” for screening men doesn’t mean there’s evidence of no benefit. It means the research hasn’t caught up. Talk to your doctor. Know your T-score. Track it over time. If your results are normal and you have no major risk factors or new health changes, most guidelines suggest repeating the scan every 3-5 years. If you have low bone mass, are starting new medications, or have a new fracture or a major change in your health, talk to your doctor about retesting sooner. That way, you can see how your bones respond and recalibrate your plan if needed.
Heavy compound lifts. Twice a week. Thirty minutes. Deadlifts, squats, overhead press. The LIFTMOR protocol: five sets of five at greater than 85% of your one-rep max [14]. If you’re new to heavy lifting, get coached first. The protocol was safe for postmenopausal women with osteopenia, so your excuses are limited. Sixty minutes a week. Less time than a strategy meeting that could’ve been an email.
Add impact loading. Ten jumps, three times a week. Two minutes total. Do them in your office. In a hotel room. Between calls. Nobody needs to know. The Hinton trial demonstrated significant gains in bone mineral density with a jumping protocol alone [15]. This targets the femoral neck specifically, one of the most fracture-prone sites in the body.
Get the basics right. Aim for at least 1.2 grams of protein per kilogram of body weight. For calcium, get 1,000 to 1,200 milligrams a day, ideally from foods like dairy, leafy greens, or sardines [17]. For vitamin D, aim for 600-800 IU daily, or more if you’re often indoors [18]. If you’re not sure what this looks like, here are some ideas: Breakfast could be Greek yogurt with berries and seeds. Lunch might be grilled salmon on a leafy salad with chickpeas or beans. Snack on cottage cheese or almonds. Dinner could be roasted chicken with spinach and broccoli. Even adding a glass of milk, some cheese, or tinned sardines helps with calcium. These aren’t just supplements. They’re what your bones need to get stronger.
The Kids Window
If you have kids under 18, this is the most urgent part of the newsletter.
Kids build 90% of their bone mass by 18 [6]. What they do as kids and teens shapes up to 40% of their adult skeleton [6]. The best time to build bone is late childhood and puberty. Some of the best options: sports and activities that involve jumping, running, and quick changes of direction. Think soccer, basketball, volleyball, gymnastics, tennis, dance, or parkour. Even playground games like tag and hopscotch count. The most active kids end up with 8-10% more bone at the hip as young adults, and that edge lasts [19]. Schools that keep kids moving through puberty see fewer fractures years later [20].
This window doesn’t stay open. You can’t build bone at 40 the way you could at 14. Again, get your kids moving: sports, climbing, jumping, roughhousing. Even wrestling on grandma’s bed is good, just avoid the elbow drop.
Upward ARC: Capacity
This newsletter is part of the Capacity pillar in my Upward ARC framework. Activate keeps your body running, and Recover helps your nervous system reset. Capacity is what lets you perform better over the long term. Bone health is the most direct example of capacity I know. Everything else (your fitness, your career, the years you want with your family) rests on a physical foundation. That foundation is either getting stronger or weaker every day. Unlike your revenue or heart rate, you can’t feel it changing.
Twenty years of competitive wrestling broke some of my bones, but it also made them stronger. During routine MRI scans, radiologists often commented on how dense and unusually strong my bones were for the areas they checked. One even said I’d likely avoided injuries that would have sidelined others. The same sport that broke some bones was quietly doing what matters most: putting stress on my skeleton year after year, forcing my bones to get stronger.
That’s Wolff’s Law in a body, not a textbook.
I’m not competing anymore. But I’m committed to investing in my bones, as I did during training. Heavy lifts. Impact. I know what the science says about what happens when you stop.
I still do a diving elbow drop, by the way. These days, it’s on the couch with my boy, Magnus. He’s nine. He thinks it’s hilarious. He has no idea he’s building bone density.
My collarbone healed in six weeks when I was eight. Forty years later, nothing heals that quickly. We’re all losing bone now. The only difference is whether we’re taking action. And whether our kids are building what they need before their window closes.
Stay healthy.
