Yoon Si-yoon revealed his current and target body fat percentages.

In the episode of SBS's entertainment program ‘My Little Old Boy’ (hereafter ‘My Little Old Boy’) aired on the afternoon of the 1st, Yoon Si-yoon was seen exercising from the morning.

In this broadcast, he ran to the gym just 50 minutes after waking up. Currently in the process of returning with the casting of ‘Taxi Driver 3’, he said, “I’m controlling my weight because I want to give off a tired look. Last week when I checked, my body fat percentage was about 6.5%.”

He then added, “My target body fat percentage is 5%,” surprising the production team and the panel.

It airs on Sundays at 9:05 PM on SBS.
