My story

I rebuilt my own body. Now I do it for others.

A decade of professional handball across Europe gave me a career I loved - and a body that kept breaking. Injuries, surgeries, and long stretches where I wasn't sure I'd move freely again.

Doctors and physios patched the symptoms, but nobody fixed how I actually moved. So I went and learned it myself: functional anatomy, biomechanics, and corrective coaching through NASM and the Brookbush Institute. I rebuilt the way I move from the ground up.

I know exactly how it feels to be told to just stop - and I know it doesn't have to end there. That's the work I do with you.

"I'm not coaching from a textbook. I lived the injuries, and I found the way back."

The method

Coaching built on evidence and experience I've lived through.

Pain-free patterns

Every program is designed to restore natural, efficient movement without aggravating existing pain or compensations.

Functional anatomy

We train the body as an integrated system - understanding how joints, muscles and fascia work together in real life.

Biomechanics

Movement is assessed and progressed through the lens of mechanics, load and individual capacity - not generic templates.

Who it's for

Movement problems don't discriminate.

Professional athletes

Optimize performance, recover from injury and extend your career with movement that respects your sport.

Deskworkers

Undo the damage of long hours sitting. Rebuild posture, mobility and strength for the workday and beyond.

Everyday people

Whether you're getting back into training or starting fresh, move better without intimidation or jargon.

People in pain

Chronic or recurring pain isn't a life sentence. Get a plan that addresses the cause, not just the symptom.

What's included in coaching

  • A movement assessment from video you film - no clinic visit needed.
  • A personalized corrective plan targeting your specific joints and pain points.
  • Clear exercise video guides so you always know exactly how to perform each move.
  • Weekly adjustments as you progress - your plan is never static.
  • Direct messaging access to me between sessions when questions come up.

Credentials

Qualified by study and by scars.

That journey led me to NASM, the Brookbush Institute and a deep dive into functional anatomy and biomechanics. Every session is shaped by that combination.
