3 months off work, now pain-free: Willem

Willem was off work for about three months. Now he is pain-free and working towards a new goal.

“My complaint is completely gone now. It did take a really long time. About nine months in total, I think. But now I can say it’s really 100% gone.”

Willem tells his story (14 seconds, in Dutch)

No doubts

Willem already knew coach Jari. When his complaints started, he asked whether Jari could do something about them. He could. After that conversation Willem said yes straight away.

“I had no doubts about starting the training.”

The Body-APK

A Body-APK was part of the process: an analysis of your posture and how you move. “That was a new word for me,” says Willem.

He did like the idea of having the way his body moves checked. “I felt positive about that, I really wanted to do it.”

The analysis showed what they could work on. Unlock Motion, our small-group programme, always starts with a Body-APK like this too.

36 sessions

Willem did a course of 36 sessions with Jari, spread over a number of weeks. For the first half they did three sessions a week.

“That was very intensive,” says Willem. But the results matched the effort. In the beginning they worked a lot on his core muscles.

“That paid off right away. Not that everything was gone, but you could feel a lot of improvement.”

About Jari: “He has a very personal and motivating approach and way of coaching, so that was really nice. It was no chore to come to the sessions either.”

“After eight weeks of training with Jari, I went back to work.” His complaints were not gone yet at that point, but he could do his work normally again.

A new goal

Before his complaints started, Willem could run a half marathon. He is not there yet.

“I won’t be able to do that right now, but that is where I want to get back to. So we are slowly going to work on that again.”

Apart from that he keeps moving, as always. And he stays down to earth. “Before my injury I also thought I would never get injured.”

It’s just nice to stay active, to stay fit.

This is Willem’s experience. Every body is different. You can find more member stories under Testimonials.
