A rare gym in that you can pay for just one time, and many other options in addition to the usual year-long memberships. It is rather small, but clean and not too crowded. I haven't been to the organized classes yet, but there are a variety of possibilities as well as messages and a sauna. Most of the staff speaks English and are very nice and helpful. They have timetables etc. available in English as well.
All the gym equipment isn't state-of-the-art and they don't have every possible machine under the sun or every kind of class available at all hours of the day, but otherwise I don't have any complaints.other than that my impression has been very positive.
If you've just moved to Prague or are just passing by and want to hit the gym, this place is the best I've found for that purpose.
They also have a small play-area for kids by the reception. read more
