Why runners train at Fundamentals
Most runners love to run but often skip the strength and stability work that prevents injuries and improves efficiency. That is where we come in.
Our training focuses on the core and the supporting muscle groups that keep runners healthy such as:
Lower leg stability for reduced calf issues
Hamstring strength for better stride control
Hip and upper leg power for improved running economy
Posture and alignment coaching to support long distance performance
We see exactly the same patterns in many runners and know how to fix them. The combination of regular running with targeted strength is the fastest way to progress.

A welcoming community in the heart of Haarlem
A place where runners feel at home, grow strong and progress together
This is your moment to join the tribe and take the next step toward a stronger, healthier running lifestyle.
Are you an expat living in Haarlem and looking for a way to feel stronger, healthier, and more confident? Finding the right gym in Haarlem can be challenging — especially when you want more than just a place filled with machines. You want results, guidance, and a welcoming community. That’s exactly what we offer at Fundamentals Haarlem.
Five new machines are coming to Fundamentals in Haarlem from September. Our gym has been running for around six years, and more people are finding their way to Fundamentals. That is great: Haarlem is getting fitter, while demand on the gym is increasing. We have therefore decided to invest in the gym so we can offer as many people as possible a pleasant place to train within our available space. More equipment means more people can perform their exercises at the same time.
At Fundamentals, we understand that as an expatriate, finding a gym that aligns with your unique needs can be challenging. Located in both Haarlem and Alkmaar, Fundamentals offers a personalized approach to fitness, ensuring that every client, regardless of their background, feels at home.
