This is such a clean and nice gym and it's literally right next-door to the train station. I stayed…read morein a hotel up the street called the Hotel Continental (great deal!) and they have an agreement with this gym so you get free passes. They have classes and a pretty complete weights floor with lots of cardio equipment. The gym is floor is expansive and has nice subdued lighting and they have some really fun healthy vending machines...even one with açaí super food cups. The crowd is diverse and very polite as people tend to be in Switzerland. The locker rooms are large and there are showers, steam rooms and saunas. I didn't see any towel service so definitely bring your own towel and also bring your own lock so you can lock your locker as I believe you may have to buy one otherwise. Any padlock will do; even a small luggage lock works to secure the lockers, which is what I used. It might be a good idea to bring your own flip-flops or shower sandals too, if you plan on taking a shower and using the sauna/steamroom. It seems that if you get there by 9:20 pm you can stay until 11pm. At least that's what the front desk said! Official hours for the gym are 5:00 AM to 11 PM Monday to Sunday. There are training coaches available 7:00 AM to 9:40 PM Monday to Friday and from 9:00 AM to 5:00 PM on Saturday and Sunday. Enjoy your workout.
