On her April 27 Naver 'V' live broadcast, IU shared that she works out nowadays and out of all, she does the plank a lot. She stated, "So now I have abs. People don't believe me when I say I have abs but I actually have them quite often."
She continued, "Doing planks created abs. Not entirely but I have it at the upper abs. I can't make lower abs how hard I try, though."
