Sorry, as far as I know, there doesn't seem to be a decent gym in Putian. I once went upstairs to the Guangxin Theatre to see it. There is a gym, which is fully equipped, but the ventilation is not good. That's a ship.
There is one above the art gallery that is ok. I practice there every day.
The annual card is 500, the semi-annual card is 300, and the season card 180 is more expensive for girls, because aerobics instructors are specially invited. The above is the price for boys. I forgot how much the monthly card is ~ ~
