Gain showed an impressive pole dance.

In SBS "Strong Heart" aired today, Gain came out as one of the guests.

Gain said, "I'm the type to gain weight easily. I have to eat less and exercise a lot. I'm learning pole dance these days, but you get worn out within 30 minutes because it's so hard. But you lose a lot of weight."

Then, Gain danced to her song "Bloom" with a pole.
