She revealed that the secret to her hot bod is none other than hard training.�Hyunyoung shared more of her secret as she said, "Strength training is addictive. The more I do, the better I feel as my muscles tighten. Now I even feel uneasy if i do not exercise. To be honest, I do not favor cardiovascular exercises because I can't catch my breath, but I am overcoming it by switching strength training and cardiovascular back and forth."

Along with exercising, Hyunyoung claimed to be a fan of sports as she enjoys yoga and golf. She added, "I am now an expert of losing weight. For brunch, I have a banana, sweet potato, eggs, etc, then eat what I want to eat for lunch and eat little for dinner. When I crave high calorie food, such as pork belly, I wait and eat it as soon as I get up in the morning."

Hyunyoung's killer abs sound like they're the result of sacrifice and discipline.More of Hyunyoung's tips and photos can be found in the March issue of 'Lady'.�
