健身房 (jiàn shēn fáng): 体育館

I go to the gym to work out for an hour after work every day.

This gym is very close to my home; it only takes five minutes to walk there.

On weekends he usually goes to the gym to swim, not to lift weights.

I want to get an annual gym membership; that way it's cheaper than paying each time.

This gym offers personal trainers and yoga classes.
