Yingpaisi Fitness Club, with good environment, complete facilities and many courses, has several branches in Suzhou (Workers' Cultural Palace, Sports Center, Park Impression City, Mudu). Annual card is 2280 yuan.
I am exercising there now. It's really good. Interested in joining my QQ group (5450 1673). They are all members of IPAS (this is a private group).
Any time is fine! There are different classes every day!
