Very friendly and professional trainers, who take your medical problems into account, keep an eye on you, and offer good advise and tips.

Price is about 45 euro per month. For that you can come as often as you like. You can have a Probetraining for free. The programm itself takes you less than an hour if you do things in a normal tempo.
Only disadvantage is that they close at 20:00, so you can't really go there anymore after work (unless you finish at 18:00).
