[시작하게 된 계기]: I started when I was a third grader in high school. I was originally very skinny. But when I was in third year of high school, I binge ate due to study stress, and eventually gained a lot of weight. In addition, my mental stress increased so I decided to lose weight. At first, I thought about how to overcome it, but my dad, who exercises every day, advised me to exercise. gave me advice. So I worked out with him every week. I felt refreshed and my stress disappeared when I exercised. And I lost weight and improved my physical strength, so I could concentrate on studying. So, I have been building my physical strength so far with this work.
