In a 2016 interview with Harper's BAZAAR U.S., Wang revealed she "usually lift weights" each day but "not much — two pounds and three pounds. It takes me a total of five minutes." She also loves bike riding and playing golf.

Wang said she typically eats healthy. She said, "I go through phases with what I eat for lunch: I like sashimi with brown rice and vegetables, Chinese steamed broccoli with chicken and rice, or the artichoke salad or fish from Sant Ambroeus."

And she only drinks water after giving up Diet Coke which was "the hardest thing I ever gave up."
