The Privilege of Sore Legs

Until my early thirties, I felt immortal. Not in any dramatic way. I just never thought about it. Doctors, nutrition, sleep, fitness. None of it registered as urgent. My body worked. It got me through long hours, career changes, and everything I threw at it. I never stopped to ask whether it would keep working.

I skipped checkups for years. I had health insurance at every company since I was twenty-five and never used it. I avoided blood tests because needles made me panic. I ate whatever was available and slept whenever my schedule allowed. Exercising had not been part of my life since high school.

I was not making a conscious decision to neglect myself. I simply did not think about it. That is what feeling immortal looks like. It is not arrogance. It is absence. You do not feel the cost until the bill arrives.

What I started to see

There was no single moment that flipped the switch. It was a slow realization of things I observed over time.

I watched people around me get older. Some of them spent their final years in bed, unable to walk, unable to dress, unable to hold the people they loved. They needed someone for everything. Their last chapter was dependency.

Others lived differently. They stayed active until the end. They walked. They moved. They carried their grandchildren. They showed up to every family meal on their own feet. When they left, they left standing. Not lying down.

That contrast stayed with me. It was not something I read in a book or heard in a podcast. I saw it in real people, real families, real endings. And I started asking myself a question I had never considered before: how do I want to get old?

Not how long do I want to live. How do I want to live while I am living.

The numbers that matter

When I started researching, I found data that made the abstract feel concrete.

VO2 max, the maximum amount of oxygen your body can use during exercise, is one of the strongest predictors of how you will age. Studies by Paterson and Shephard established a threshold: below 18 ml/kg/min for men and 15 ml/kg/min for women, basic independence starts to collapse. You cannot rise from bed without help. You cannot tie your shoes. Walking becomes exhausting. You need someone for things you never thought about.

That threshold is not theoretical. It is a line. And every decade after thirty, your VO2 max drops roughly ten percent if you do nothing about it. Fifty to seventy percent of that decline comes from inactivity, not biology. That means most of the loss is a choice.

Strength matters too. Benchmarks like a back squat at 1.5 times your bodyweight and a deadlift at twice your bodyweight are not just gym goals. They represent functional capacity, the kind of resilience that keeps you independent, mobile, and capable of protecting yourself as you age.

When I look at people my age who started training ten or fifteen years before me, the gap is real. They are at a level that is genuinely hard for me to reach now. Not because the work is different, but because younger bodies respond faster. The same effort at twenty-five produces multiple times the gains it produces at thirty-eight. That is the compounding effect in reverse. Every year you delay, the cost goes up.

Facing everything

I wrote about starting my gym journey before, so I will not repeat the details here. What I want to focus on is what changed beyond the gym.

I became brave about my health. I started booking specialists, doing blood work, going to the dentist, running every exam I had been avoiding for years. I still hate needles. That has not changed. But I now understand that the discomfort of a blood draw is nothing compared to the discomfort of losing your independence.

Preventive medicine became a priority. I stopped waiting for things to hurt before paying attention. I started scheduling regular checkups and full panels, not because something was wrong, but because I wanted to know where I stood. For the first time, I was treating my body the way I treat systems at work: monitor before things break, not after.

Small issues I had been ignoring for years turned out to be fixable. A nagging inflammation that I dismissed as normal. Dental work I had postponed since my twenties. Minor things that would have taken an afternoon to fix a decade ago had quietly gotten worse. I could have addressed all of them earlier if I had just shown up.

Early detection is not dramatic. It is quiet. You catch something small, you fix it, and you move on. The alternative is letting small things grow until they are not small anymore. Every year you ignore your health is a year where fixable problems get the chance to become permanent ones.

The privilege you do not see

Something changed in how I experience hard training sessions. Every time I finish a brutal workout and I am completely spent, a thought shows up that will not leave.

Being tired from exercise is a privilege.

On that same day, in hospitals and homes around the world, there are people who would trade everything for one more walk. One more time holding a baby. One more trip carrying a child on their back. One more morning walking side by side with someone they love. They cannot do any of that. And here I am, complaining about sore legs after squats.

I cannot accept giving away that privilege. Not anymore. Because once it is gone, you do not get it back. Delaying your health is not just a personal decision with personal consequences. It is something you will regret in a way that no career achievement or financial milestone will ever compensate for.

Do it for them

There is one more angle I did not consider until recently. When you take care of yourself, you are not just doing it for you. You are doing it for the people who love you.

If you lose your independence, someone has to take care of you. That someone is usually the person closest to you. Your partner. Your children. Your family. Instead of enjoying time together, they spend it managing your needs. Instead of sharing moments, they carry obligations. You become a responsibility instead of a companion.

That is not how I want the people I love to remember their time with me. I want to walk with them. I want to be present, not as a burden, but as someone who can still show up fully. That means investing now in the body that will carry me through those years.

Start before you are ready

I started late. I know that. At thirty-eight, progress is slower, recovery takes longer, and the ceiling is lower than it would have been at twenty-five. But I also know that starting late is infinitely better than not starting at all.

If you are younger and reading this, you have something I do not. Time. Half the effort I put in now would give you double the results. A few runs a week. A couple of strength sessions. Walking every day. Drinking more water. Cutting the sugar. These are small. They feel insignificant in the moment. But they compound.

I train six days a week now. Three strength sessions, three running days. I do hybrid training, things like Hyrox that combine strength, cardio, and endurance in the same session. Research from Harvard and BMJ Medicine shows that mixing exercise types can reduce mortality risk by up to nineteen percent compared to doing just one kind. The optimal range is two to five hours of moderate to vigorous activity per week.

I will never be a competitive athlete. That is not the point. The point is that I am part of a community of people who celebrate wellness and movement. I have never felt better in my life. No headaches. Better sleep. More energy. I look in the mirror and I like what I see. Not because I look perfect, but because I see someone who is doing the work.

The one thing I would tell my younger self

Do the minimum. Just start. Walk. Eat better. Book the appointment you have been putting off. Take the stairs. Drink the water. These are not life-changing actions on day one. But given enough time, they change your life completely.

You do not need a crisis to start caring about yourself. You do not need to hit a wall. You just need to look around, observe how people age, and decide which version of old you want to be.

I chose to die standing, not lying down. I hope you make that choice too, and I hope you make it sooner than I did.
