Ian van der Werf
High-Performance Trainer
I'm Ian (1984), the driving force behind De Werf. My roots lie in elite sport, where I spent years playing in national rugby selections and working in high-performance environments. That world taught me what it takes to perform sustainably: insight, discipline and the will to keep learning. As a strength & conditioning coach, I have guided national teams and helped countless athletes and motivated individuals become stronger, fitter and more resilient. Among other roles, I am head strength coach of the Dutch Women's Cricket Team, where I prepare athletes for international competition. My style is direct, knowledgeable and results-driven, but always with an eye for the person behind the athlete. I also taught at AALO as a Master Trainer for more than ten years, training future coaches. I wrote the Bootcamp Trainer and Weightlifting Level 1 courses, among others, which are still in use today. This combination of elite sport, education and hands-on experience forms the basis of how I work.

What clients say about Ian
Discover how Ian delivers transformative training
Over the past year, I have worked closely with Ian. He tailors every workout to my needs and always takes my shoulder osteoarthritis into account. Thanks to his approach, I am stronger, fitter, and more mobile than ever. At 49, I feel more energetic and younger than I have in years.
Working with Ian has helped me get back to fitness after a long injury. In just a few months, I lost weight, gained strength, and can now easily run 5k, working towards my first 10k. His flexible, knowledgeable approach delivers real results, and I'm excited to keep progressing toward my goals.
I had been training for years, but without the results I wanted. That changed quickly with Ian. Within four months I saw clear progress, thanks to well-built training schedules and clear nutrition guidance. Finally the results I had been looking for. A top trainer.
Ian gives me warm, expert guidance and makes every session enjoyable and effective. With his help I reached my goals and even got better results than expected. The nutrition plans are easy to stick to and keep me energised all day. I should have started with Ian much sooner.
About nine months ago I turned to Ian after years of doing nothing. I wanted a different weight, more energy and a future that better suits who I am now. With his personal approach he found exactly the right trigger. I have lost over 15 kilos, sleep well again and wake up full of energy every day. Grateful that I took that first step.
Working with Ian has been a game-changer for me. His training is fully tailored to my goals and always challenges me without overwhelming me. In just a few months, I became stronger, fitter, and more confident in my body. I'm grateful for his motivation, expertise, and genuine commitment to my progress.
