There's one at the junction of Minjiang Road and Fuzhou Road, but it's relatively small ~ There's also one on Gangdong Road and next to Di Chin Villa, which is relatively large and there are more people going ~ I suggest getting a membership card ~
There is another one on the top of MacKay, which is the cinema floor. Not bad, but the location is relatively closed, which is not very convenient, but the environment is good.
However, I still suggest that you have time. It is best to do outdoor sports, such as cycling, running, swimming, playing badminton and golf. These are all good fitness programs. Breathing fresh air and aerobic exercise will be better for you ~ ~ ~:)
