You are better off going to your locality park and doing some yoga. The instrument is horrible and poorly mantained. The staff will try to convince you to pay a fee for eternity so that you cant leave. Be ready for some serious injury if you get to work out here.
once a machine stops working no one would get it repaired. The gym will close at will on any day so you may be all charged up to work out but they will tell you that they decided to keep the gym closed that day.
My experience is based on the one in Malad West near Rustomjee.
