Park Seo Jin's Screams During Yang Chi Seung's Hellish Training

Park Seo-jin underwent rigorous training from star trainer Yang Chi-seung. The episode of KBS2's "Mr. House Husband Season 2" aired on the 20th showed Park Seo-jin meeting Yang Chi-seung with his younger sister Hyo-jeong to begin serious weight management. Park Seo-jin recently started running and confessed his struggles, saying, "When I'm next to other cast members on broadcast, I look like such a pig." Yang Chi-seung, who appeared in response, looked at Park Seo-jin and remarked with a laugh, "I saw you on TV, and you don't look like this."

Yang Chi-seung expressed confidence, saying, "If you train for just one year, you can have a better body than Kim Woo-bin." Park Seo-jin and his sister then underwent body composition measurements. The results showed that Park Seo-jin, at 74.2kg, weighed more than his sister Hyo-jeong for the first time.

Afterward, Yang Chi-seung coached while eating popcorn and demonstrated customized workout methods specifically for Park Seo-jin. Hyo-jeong added to the laughter by showing suspicion, saying, "He smells like a con artist."

The final part of the training was aqua fitness in the water. During the high-intensity exercise, which required hanging onto equipment, Park Seo-jin complained of agony and regretted, "I should have lost weight. I should have stopped eating."

However, there was also an unexpected achievement. Park Seo-jin succeeded at waterskiing in just four attempts, confidently waving his hand with ease. The studio cast members also applauded his achievement, saying, "We acknowledge it today."
