Affordable Gym in Shekou or Nanshan Area

Dear Members,

i have recently shifted to Shenzhen and residing in Shekou area.

Can anybody help me out with good and affordable gyms nearby or even in Nanshan area would do?

I would want to know of a good gym that lets you pay month by month or Even a yoga studio would be cool.

Also please tell me the monthly price if you can.

Thanks in advance,
Reema
