The gym is inside the school on the 6th or 7th school. The school is on the corner of Kim Ma and Van Phuc beside RMIT.

I don't work out there much anymore, as it seems more cost effective to buy some equipment...if you have the room..it is quite cheap to get free weights and get a couple benches, however if you use alot of cardio equipment then a gym membership is still a better idea.
