Han Ga-in reveals why she started exercising: 'I was too dizzy to jump in when my daughter fell in the water'

Actor Han Ga-in has opened up about what motivated her to start working out.

On Thursday, Han shared her exercise tips on her YouTube channel "Jayubuyin Han Ga-in."

In the video, Han spoke about the relationship between strength training and overall fitness, and revealed a personal incident that made her realize she needed to get in shape.

"People don't really believe me when I say I used to be in poor health," she said. "Up until three years ago, when my second child was five years old, my health was really bad."

Han then described a frightening moment at a water park. "When Jay was five and Jeu was around two, we went to play in the water. Jay was playing with friends and suddenly started struggling. I was watching but I was so dizzy I couldn't get there fast enough," she said, confessing that her vertigo had been serious at the time.

"I called my husband over quickly and he rescued her," she said, adding that the situation had narrowly been averted.

Han said she has since been consistently exercising to restore her health. "I work out to survive," she said. "After trying it, I realized that strength training is definitely what improves your stamina."

Han married actor Yeon Jung-hoon in 2005. The couple have a son and a daughter.
