I do not recommend Cal Fitness. Their sales tactics are often very deceptive and they seem to have a very bad rep in HK. Also they really do not give a damn if things break down and don't fix them for ages. The TST Gym just opened 3 weeks ago and there is no water in the drinking water fountains. Members have been complaining for weeks with no response from the management. Finally we have decided to call up Jackie Chans agent until they fix it.
I recommend Fitness First. It is a well run Gym.
