"The Iron Girls" Yui lost weight more and more, drawing concerns from people around her.

tvN 'Inferior Girls Group 2', which aired on the 12th, depicted U-I, Geum Sae-rok, Park Joo-hyun and Seol In-ah participating in the long-awaited first boxing competition.

On this day, members of the cast iron girl group focused on last-minute training ahead of their participation in the boxing competition. U-I, who aimed to increase muscle mass, focused on strength training, but coach Park Ji-hoon expressed concern, saying, `You lost too much weight.' As a result of exercising three to four hours a day, only 1kg of body fat was lost, and there were even concerns about weight loss.




Yooi, who is currently 51kg, said "I'll eat well while managing my diet."Eat a lot of carbs," coach Park Ji-hoon advised.

Since then, Yui has worked hard to increase the amount by eating pork belly, sushi, and egg toast after exercising for bulk-up. He said "The weight is rising numerically because I'm eating hard."

On the day of the boxing competition, Kim Dong-hyun checked the members' conditions. He asked Yui "Have you succeeded in increasing your muscle mass by 1kg?", and Yui "Give me another month." I've been on a lot of diets while I was active, but I don't know how to increase it."




In response, Kim Dong-hyun said, "You have to eat more protein than you think." he advised. Then, Yui said, "I ate to my heart's content"I can't do it without exercising, so the muscle mass is actually 23kg as it was a month ago."

Kim Dong-hyun said "It's really hard to increase muscle mass. "Is your weight the same?" asked Yui, "I lost a lot of weight by 49 to 50 kilograms while exercising, but I don't know. I'm trying to get it right." The other members were worried about Yui, who kept losing weight and was drying out, but they confessed their honest feelings, saying "I'm jealous".

On the other hand, Yui passed the weigh-in measurement with 52.7kg, overcoming concerns about weight loss.
