Let your friends discover Sluis Gym and get one period of free training.
Training together is not only more fun, but also more motivating. Bring a friend to Sluis Gym Haarlem and you’ll both benefit from this offer:
one free period at the end of your contract
Here’s how it works: come to the club together and check in with the host. Experience Sluis Gym side by side — and if your friend decides to join, you’ll both receive the reward. At Sluis Gym, training is about more than just getting physically stronger — together you go further, stay consistent, and have a lot more fun.
So… who are you bringing along?
The free period will automatically be added at the end of your contract. The offer only applies if you’re both present at the time of registration.
