Achilles pain gone after 3 years: Marieke

Marieke had trouble with her Achilles tendon for three years. After her programme at CrossFit Leiden she could do everything again, without pain.

“It’s going really, really well now. I basically don’t have any trouble anywhere anymore.”

Marieke tells her story (21 seconds, in Dutch)

Trouble for so long

Marieke met coach Jari at the box. She followed him on Instagram and looked into what he does. Still, she had doubts. Not about his approach, but about whether it could still work after such a long time.

“I’ve been walking around with this for so long. How can someone solve it within a few months?”

Not what she knew

It started with a Body-APK, the posture and movement analysis that Unlock Motion starts with. Jari filmed how she walks and showed her exercises.

“This is really very different from what I’m used to.”

She had never done exercises like these. Jari calls it 3D movement.

Keep practising

Jari asked her to keep track of everything she did. That way they could work out together where it came from.

“You really do have to keep doing your exercises. Because when I didn’t, I did notice it.”

Running again

When Marieke told her story, the programme had been over for more than half a year. That day the workout included three kilometres of running.

“No trouble now, and I don’t expect any trouble tomorrow or the day after either.”

Her advice if something has been bothering you for a long time: just do it. But do the work yourself. “You have to stay behind it yourself too. So do those exercises and keep putting energy into it.”

I can do everything again now, without pain.

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