"I walk 10,000 steps a day now, whistling."

Imagine: you're forty years old. You can't stand long enough to cook. Can't go out with your kids. Getting from the couch to the kitchen is already a challenge. That was Diana's life, less than a year ago.

A body that stopped cooperating

Diana had always had some back pain. Nothing serious, she thought. Until March 2025, when everything suddenly changed. A broken vertebra, a shifted vertebra, and a double herniated disc on both sides. Daily life became a battle.

"I couldn't do anything anymore, really. Couldn't stand, couldn't cook, couldn't go out with the kids. Getting from the couch to the kitchen was already a huge challenge."

At work she managed, because sitting was fine. But at home? At home, everything was different.

From physiotherapist to hospital

Diana had been to a physiotherapist before for back problems on the other side. That had helped. So she thought: the same approach one more time. But this time it didn't work. Despite all the treatments, the pain stayed.

The physiotherapist was honest: "I can't fix this. I think you need to go to the hospital."

And at the hospital came the diagnosis. And with it, the advice: surgery. Fuse the three lowest vertebrae with screws and pins. Diana specifically asked if there was another option. If exercise and muscle training could work. The answer was definitive: no.

A phone number and a glimmer of hope

But Diana had heard through Gymbox Noordwijk and Jac about someone who might be able to help. Someone who understands posture and movement. Jari, our movement specialist at CrossFit Leiden.

"I wanted to have tried everything before starting with surgery. It was my last resort."

The physiotherapist had also warned her: if you fuse the lowest vertebrae now, the ones above will be next in three to four years. You're shifting the problem, not solving it. That stuck with her.

The Body-APK: seeing what others miss

Diana was nervous. She could barely move. What on earth was she going to do here?

Yet she started with a Body-APK: Jari's comprehensive movement analysis. He examined her posture, took photos, had her walk on the treadmill, and analyzed everything in detail. Together they reviewed the footage.

"It was bizarre. How you can see what's there, and how it should actually be. At that moment I thought: this man knows so much about it, it has to work out."

Diana describes Jari as someone with 'X-ray eyes for muscles'. "He can spot a one-centimeter hip difference between left and right. I don't know how he sees it, but it's accurate."

Step by step forward

Diana started cautiously with personal training. Once a week. To see what was possible.

After about five weeks, she started noticing a difference. Standing longer. Walking a bit further. Staying upright while cooking instead of leaning on the counter. With ups and downs, because sometimes she pushed the limits and the pain increased afterward. But that also provided insight. Every setback led to better exercises and a sharper plan.

After the summer, Diana switched to Small Group training. Twice a week, more intense. And that's when things really accelerated.

Today: a new life

Now, half a year later, Diana is a different person.

She walks 10,000 steps a day, whistling. The loss of strength in her legs is gone. The nerve pain has disappeared. She can do everything she wants again.

And the most remarkable thing: on recent scans of her back, no herniated disc can be seen. The shifted vertebra sits straight. Everything is where it should be.

No surgery. No screws. No pins.

The proof

The hospital said this was impossible. That exercise couldn't solve it. That there was only one option.

Diana is living proof that there is another way.

"It truly gave me my life back. If you have any doubts at all, I would absolutely do it."
