Very family friendly Crossfit Box that also feels like family! CrossFit Thalwil is a welcoming place where members know and support each other. At the same time Terrain makes sure that everyone is challenged enough to make progress, no matter at what stage of their fitness journey they currently are.

Great CrossFit Box ! Great atmosphere, super friendly and knowledgeable coaches! Also very kids and family friendly.


Have been going to Crossfit Thalwil regularly for 5 months. Great atmosphere and very professional coaching! Workouts are challenging but the coaches always give good scaling options to make sure everyone gets a productive workout.
Terrain has also built a great community around the gym. I always look forward to going there.
I highly recommend it to anyone in the area looking for a new workout routine!


Highly motivating and experienced coaches, a very well equipped gym and a great atmosphere and collegiality among the members. It is simply fun to train here - and will bring you improvements in other sports such as cycling, running or skiing as well.


Crossfit is not just a workout it is a lifestyle change & the Crossfit Thalwil box brings the sense of community and belonging. Terrain is a great coach & person. He is very committed to the people who belong to his community & he & his team make the workouts super fun. I have personally improved my strength over the last few months without injuries. My children enjoy going to the teens classes too. I look forward to my Workouts. Everyday is different & it challenges you to be a better version of yourself. Whatever your motivation is, it is worth coming down & having some fun with us.


Not just another CrossFit box! Thalwil CrossFit is super family friendly with classes for everyone! My kids and I have loved working out here for the last 5 months. Everyone is welcoming; you never feel intimidated. Great group of people to know and work out with!

Simply the BEST place for Cross Fit and not only. Terrain has a deep knowledge of his job and also managed to keep a happy and friendly atmosphere in the gym. There are more classes like Pilates, HIIT so can have a complete weekly training and achieve my fitness goals. The family friendly environment makes it even easier for me to join the classes as i can bring my child with me. There is a great play room where the little ones can play while we train. How cool is this!

The most intense workout I have ever done but Terrain makes it fun! The playroom for kids is awesome, finally a family friendly gym around these parts.
