Weekend early morning at Bintaro XChange, there are already crowd of people who are exercising. They are running, jogging, yoga, tai-chi, aerobic, etc. Different to other malls where are very quiet since they are not opened yet, mostly at 10 AM.
Do not worry, you can go there though not doing any exercise such as family gathering or just taking a walk around the park.
I ran on the outer ring of BXChange where it has 1,2 km per lap. Honestly it was a bit dangerous since vehicles are still allowed to pass through the outer ring. But the jogging track inside the BXChange was really full and really crowded. You can not run in that situation.
