Actress Lee Si Young recently revealed the reason behind her passion for boxing.

After she entered the '66th National Amateur Boxing Tournament', Lee Si Young held an interview with 'One Night of TV Entertainment'. She shared, "Usually when I get to the third or fourth round, I'm worn out, but today I didn't even sweat. I think I was so nervous I wasn't able to perform�at my full potential."

She continued, "People always ask why an actress like me started standing in the ring. When I do have [boxing] matches, I get scared and nervous. However, I was able to endure all of this, not caring about whether I win or lose. Now I feel like I have nothing to be scared of. Boxing has become another dream of mine."
