Harder is boutique training studios.

You will find here:

– HIIT – intensive interval training using functional training equipment. During the HIIT class you burn hundreds of calories! The trainings are so varied that you will never do the same set of exercises twice in one session!

We recommend this classes for people who are at the beginning of their adventure with training, as well as people at the advanced level.

Every day of the week the trainings are focused on other parts of the body.


– Mobility – We work to improve the flexibility and mobility of the whole body. We reverse the effects of prolonged sitting. We relax tired muscles and increase the range of movement of your joints. An ideal workout complement  for active people to complement their training. If you complain about the pains typical of our civilization (back, neck), then these classes are for you!
