From weight loss to building strength
Your personal trainer in The Hague
Whether you want to lose weight, get stronger or rebuild your mental resilience, at De Werf you work on both body and behaviour. We start by reflecting on where you are, build a rhythm that fits your life and work towards results that last. No quick fixes. Personal training, physiotherapy and lifestyle coaching sit under one roof, so your journey holds together from start to finish.
Our approach is integrated
Physical training
Physical training starts with listening: to your body, your limits and your goals.
Injury recovery
Understanding the root cause is the key to learning to trust your body again.
Nutrition & lifestyle
We start with your lifestyle. We look at how you eat, exercise, think and recover.
Behavioural change
Change begins with understanding: your habits, your motivations and your vision for the future.
Burnout and stress
Recovery starts with space: for your peace of mind, your own rhythm and your recovery.
Manual therapy
We’ll start by understanding how your body moves and where tension builds up.
Physiotherapy
We listen to what your body is telling us and identify which movements promote recovery.
Massage
Helps you recover by releasing tension and restoring your body’s flexibility.

From Reflection to Rhythm and Results
Change always starts with self-insight and accepting what you find. Which means your goals often call for a broader approach than personal training alone.

Real reviews from real clients
Read what people say about De Werf.
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.
