I joined Leo's (located on
Leopoldstrasse, number 15 I believe).
It is rather expensive with the monthly membership running at €80 euros. Plus, there are no water fountains and only a pay to use towel service.
Coming from New York City, I was shocked. For $40 a month you could get an impressive gym with tons of free weights, machines and cardi equipment (not to mention complimentary towel service and water fountians). The equpiment at Leo's is decent at best. There is no swimming pool or indoor track either. It is supposedly a ritzy gym, so when you actually sweat and work out, people tend to notice. Who cares- for $80/month I should be there 24 hours a day.
A colleague belongs to Elixia and has mentioned it to be a superior gym to Leo's, at about € 50/month.
Hope this was helpful.
