Kahi, I thought she was a mom with strong abs.

Kahi, a member of the girl group After School, shared her daily life.

On the 25th, Kahi wrote, "Stand facing the mirror and maintain proper posture. I have lived with the importance of correct posture for a long time, but with two children, housework, and stretching habits, my body is becoming more and more bent and my body shape is changing a lot."

He added, "This year's resolution is to maintain good posture. Tuck in your belly button, pull it in, tighten your lower abdomen, and tighten your Kegels. Close your rib cage, strengthen your inner thighs, and stand with the inside of your feet fully touching the ground. Make your wing bones symmetrical and get down."

Kahi said, "Even just for ten minutes a day makes me sweat. How much has my body changed? My body, which I know best. My body, which I can change best. Let's try it together. Let's change it together."

Kahi's appearance was captured in the released photo. Kahi is standing with the correct posture in front of the mirror.

Kahi married a businessman in 2016 and has two sons. Currently living in Bali.
