I've done 30+ burpees a day for 758 days. No misses.

(30 a day for the first eight months, then 50 a day since.)

That's around 33,000 burpees.

It's not the most glamorous flex. A burpee is about the unsexiest movement ever invented.

And a strong contender for having the ugliest name too.

But the streak has taught me more about consistency than every gym membership I ever paid for combined.

People assume the hard part of a two-year streak is the burpees. It isn't.

They take about seven minutes a day. Run that across the whole streak and it's under 90 hours. Less than four days of my life, spread over two years.

Most men spend more than that in the gym parking lot.

The hard part is everything else. The fever. The three-hour night. The wrist that hurts. The kid who wants to play exactly when you need to train. The morning your body decides to feel like a boat in a storm.

These are the five days that tested the chain hardest. They're the whole reason the streak means anything.

1. The day my balance disappeared

We were eating breakfast at a hotel buffet in Istanbul with my wife's family when it hit without warning.

I felt like I was on a boat. The floor rocking. My balance gone.

I want to be honest about where my mind went, because yours would go there too.

Brain tumor.

My mind skipped dehydration and inner ear trouble and went straight to the worst case scenario.

Back in the hotel room, I tried to work out what was happening. And training was the last thing on my mind.

But I had the habit. I'd done 50 burpees every day, and this one wasn't going to be an exception.

So I did the softest burpees of my life, on top of the hotel bed.

I still don't know what the balance thing was. It eventually passed.

When your mind goes somewhere terrible, a fixed ritual is one of the few things that holds still.

The world had tilted. The burpees hadn't. Fifty of them, same as yesterday, same as every day before. That sameness was what I needed that morning.

2. The fever

I was home from work with a 39.5°C fever (103°F).

But the most important campaigns of the year were going live the next day, and I didn't feel I could leave my colleague to finish alone.

So there I was, working from home and getting more delirious by the hour.

I was terrified of making some half-thought mistake that would cost the company real money.

By the time I'd finished, I was wrecked.

But then I remembered the burpees.

This is the part that's hard to explain to someone who hasn't run a streak.

A sane person looks at that fever and says: you're sick, rest, nobody cares. And they're right.

But the person keeping a chain alive knows something else. The fever passes. And the day after it's gone, the chain either exists or it doesn't.

So I did 50 of the softest burpees ever, the same move I reach for on every hard day. Barely more than lying down and standing up again.

The campaigns went out. The fever broke a few days later, and the chain stayed whole.

The ritual let the illness run its course without taking the streak down with it.

3. The wrist

A sharp pain started building in my right wrist.

Normally not a big deal. Except burpees drop you to the floor through a push-up, straight onto your wrists.

The obvious fix was to skip.

I tried something small first: doing the low part on my knuckles.

It worked. They weren't used to the pressure, so they were scraped and scabbed for the next few days. I didn't care.

The burpees got done. The wrist recovered, and I eased back to normal.

Adjustment saved the streak that week. When something hurts, you change how you do it and keep going.

The habit survives because it bends. Most people break their streaks because they think a workout has to look a specific way to count.

4. The three hours of sleep

Kids wake up in the middle of the night sometimes, and when they do, the whole household is up.

That night I got three hours of sleep. Then a brutal workday, and a hard deadline I had to stay late to clear.

By the time I got home, every cell in my body wanted one thing: eat, then collapse into bed.

And then, just before lights out, I remembered I hadn't done my burpees.

This was the closest the chain ever came to breaking, and the cause was plain forgetting.

So I knocked them out on the living room floor in the dark.

The softest burpees ever, again.

I barely remember doing them. That's the point. On a day that empty, the habit runs on reflex.

Seven minutes of movement on a day like that is a vote for the person you're becoming. And on a three-hour-sleep day, just casting the vote is winning.

That night also changed one thing permanently. My watch now vibrates every evening at 8 p.m. as a last backup, just in case the day has been super busy.

5. The daughter

One evening I was mid-set when my daughter decided it would be great fun to interrupt.

She crawled in front of me, circled around behind me, grabbed one of my legs and held on.

It's late and I'm tired. And I'm acutely aware that one careless kick back could hit her.

So I search the living room carpet for any free spot where she isn't.

One burpee. Interrupted. One more. Interrupted. One more. Interrupted. One more. Interrupted.

You know how this goes. The set took about three times longer than usual. That's just life with a child.

And somewhere in there is the best training tool nobody sells: she climbs onto my back mid-burpee and I do them with her on me. A human weight vest, plus father-daughter bonding at no extra cost.

Which is the lesson I keep coming back to: obstacles are part of the habit.

At this stage of my life, the interruptions were the workout.

What the chain built

Back in January I went to the doctor about an ear problem. He ran through the usual questions.

"What do you do for a living?"

Marketing.

"Do you sit at a computer a lot?"

All day.

"Then I'm surprised you have such good posture."

I froze.

For thirty years I'd heard the opposite. Don't hunch. Stand up straight. You look shorter when you do that.

I'd accepted it the way you accept your height. Permanent. Just how I was built.

Five hundred days of burpees had altered something I'd stopped believing could change. And it took a stranger to notice, because I couldn't see it myself.

Then it happened again.

A colleague walked past my desk one afternoon and said, unprompted, that I had crazy good posture.

A few days later he was joking that I had the best posture in the office.

The best posture in the office. Me. The kid who spent thirty years being told to stop slouching.

That's the strange thing about a daily habit. The changes are invisible right up until they aren't.

The posture wasn't the only one. I'm more muscular now than I've ever been, and my obliques show. I'm lighter on my feet and more flexible. My face looks better than it did at thirty.

I was obese at 29. And now at 39, I'm in the best shape of my life.

The kettlebell work and the food came later, built on top of the burpees. But none of it would exist without the chain underneath.

The burpees were the proof that I could keep a promise to myself, and everything else rested on that proof.

What 758 days taught me

The real lesson is the thing all five days point at, and I'll say it plainly.

Keeping the habit alive is the number one goal. You're allowed to make it easier or split the number across the day.

I survived every one of my hardest days with the same move: shrink the demand, keep the chain.

Now look at what the standard advice would have said on each of those days.

Rest when you're dizzy. Rest when you're sick. Rest the wrist. Sleep when you're exhausted. Wait until the child is in bed.

All sensible. Follow it on all five days and the chain breaks five times in two years. And I'd instead be writing about restarting right now.

The only person grading your burpees is future you, and the only question he asks is: is the chain still there?

I think of it like a wall calendar full of X's. Each day you show up, you mark one. Your one job is to keep the chain unbroken.

I had one hanging on my wall for the longest time: an unbroken run of X's from the year I went without junk food.

Same logic as the burpees, just a different column.

Fifty burpees is easy to mock. A two-year unbroken chain of them is a different beast.

Before you start, answer one question.

What's the version of your workout that could survive your worst day of the year?

If you can't answer that, what you have is a plan for a good week.

What most busy dads need is to stop treating one missed day as permission to miss the month.

Start small enough that you can't fail on your worst day. Then protect the chain like it's the whole point.

Because it is.

See you next week.

Warmly,

Bjorn
