What our members say about Happy Bodies Zeist
One 4.6 rating based on 74 reviews
Small and fine gym. I’ve been going here for 7 years now, so that might say enough.

I am writing this for my older friend who trains at Happy Bodies, but is not very handy with the computer herself. Ever since she has been training at Happy Bodies, I only hear wonderful stories about the great personal guidance, pleasant atmosphere, and the sweet, interested manager Zee, who always has a listening ear for my friend. The program consists of short, effective sessions, and she has not had a single injury yet. In short, on her behalf: hats off and keep up the good work.

Well-organized gym, small-scale. Staff know you by name and are involved. Zee recently took over as club manager. She is doing such a great job! Compliments to her and the team.

I have been with Happy Bodies for over a year now, and I am super satisfied. There is a safe, warm atmosphere (with a charming interior as well, which I am sensitive to) and great trainers. I do both Milon and strength training, and thanks to this combination, I no longer have any trouble with my back and hips. So, very satisfied!

Super nice gym! I have been coming here with pleasure for years and have achieved great results. The staff is very friendly and always helps with everything. Zee is the new club manager and she is doing a very good job. I'd love to keep coming here with pleasure!!

Happy Bodies Zeist is definitely worth it! The atmosphere is pleasant and welcoming, so you feel at ease from the very first moment. The guidance is excellent: personalized, caring, and they’re always there to help you figure things out. The manager is great, and you can really tell they’re committed to helping you reach your goals. I’m very satisfied and definitely recommend this gym! 💪
