Founder/Director of the X-Training School
To inspire, educate and share my passions is the foundation of my work.
I’m committed to my profession as a consultant, speaker, and education provider in the field of Sports rehabilitation and Performance. I want my students to gain valuable insights so they can achieve a greater potential either as a sport medical expert, physiotherapist, or sport specific coach, I find it extremely nourishing.

I thrive for excellence and set high standards towards the quality of the material I write and teach. The human body fascinates me, I always aim to translate the complexity of human function into progressive and highly effective performance enhancement techniques and rehabilitation & injury prevention applications.

I  love sharing my experience as an endurance athlete through the training camps I offer. I enjoy helping others to maximize good health with a balanced training regimen, and to achieve greater performance on and off the trail.

20 years of experience on an international platform.
