On the recent episode of JTBC's 'Serial Shopping Family', the MCs talked about how they exercise either by going to the gym or using a machine at home.

When Sunny revealed just how much Girls' Generation practices their dance routines, the MCs realized she didn't need to separately exercise at all!

Sunny shared because she's made gym memberships but not used them at all, she tends to use a rowing machine while watching TV. She also admitted, "I don't exercise. I just lay on my side and watch TV."

Then the MCs pointed out, "That's because they have to practice so much, and that becomes exercise in itself. When a song comes out, how much do you practice [the choreography] in a day?" Sunny replied, "There are times we practice 10 hours a day. Because we have to rotate around to match the member's schedules," surprising the MCs.

On another note, Sunny also shared what type of bar food she likes best. Sunny shared, "Rather than dry bar food (like dry meat and fish) I like to eat fruit [while drinking]."
