You have to go in and see the scale, the number of treadmills and the size of the equipment area. Generally speaking, the air on the ground is better than that in the underground gym. If you like classes, you should also look at the gym and spinning room. I'm afraid there are fewer treadmills and more people to wait, but it won't be your turn. If the scale is good, a year 1000 yuan is ok, not expensive.
