“The Ultimate Self-Management King – Yoon Si-yoon Appears on SBS’s My Little Old Boy”

Actor Yoon Si-yoon first gained public attention through the 2009 MBC sitcom High Kick Through the Roof. While the show brought him recognition, it wasn’t enough to label him a “star.” His real breakthrough came with KBS2’s Wednesday-Thursday drama Bread, Love and Dreams, where he played the lead role, Kim Tak-goo. The drama hit an astonishing viewership rating of 50%, catapulting him into top star status. These days, with the changing media landscape, even a 10% rating is considered a huge success—so 50% is nearly unimaginable now. Ever since Bread, Love and Dreams, Yoon Si-yoon has been regarded as a true star. Now, Yoon Si-yoon has newly joined the cast of SBS’s My Little Old Boy. Born in 1986, he’s now 40 years old in Korean age—or 456 months. As an unmarried man past the typical marriage age, his appearance on the show feels fitting. While he was a familiar face on KBS’s 2 Days & 1 Night, his appearances on variety shows have since become rare. This marks the first time he’s featured in a program for a full hour, showing not only himself but also his home and private life—hence, the public’s growing interest. On My Little Old Boy, the show revealed Yoon Si-yoon’s daily life, which was quite unusual. Beyond his star quality, the unique way he lives drew attention. His day started and ended with alarms—he divides his day into scheduled time blocks, guided entirely by alarms. Below is a chronological account of his daily routine, from waking to sleeping. Alarm King – Living by the Minute 7:00 AM – Wake UpThe lights in his room automatically turn on, and his alarm goes off. He gets up immediately and makes a protein shake for breakfast. He cleans up right after using each item. As he’s making the shake, another alarm sounds. 7:03 AM – Take Protein and SupplementsRight on time, he drinks the protein shake and takes his vitamins. Then another alarm. 7:07 AM – Vocal Warm-UpsEverything he does is followed by an alarm, prompting a production staff interview. Yoon Si-yoon:“I schedule my alarms the day before. A monthly and weekly plan is a must. If I don’t plan my day, I might waste it doing meaningless things outside. I’m terrified of becoming lazy. I’m actually very lazy by nature, so if I don’t plan things, I won’t get anything done. Really, truly.” Production Team:“Do you get anxious if your schedule isn’t followed?” Yoon Si-yoon:“I feel uneasy. Things fall out of place. I feel most comfortable when I live according to plan—it energizes me.” To avoid becoming lazy, he meticulously follows his alarms. Even during vocal warm-ups, he cleans the used cup immediately. He practices vocal exercises while lying near the window with a view of the Han River. Then another alarm sounds—time to run to the gym. Bodybuilding King – Aiming for 5% Body Fat 7:50 AM – Gym RunningHe begins running as soon as he arrives. Production Team:“You seem to have lost a lot of weight?” Yoon Si-yoon:“I’m preparing for Taxi Driver 3. I want to create a character that looks emaciated and sunken.” Production Team:“What’s your current body fat percentage?” Yoon Si-yoon:“About 6.5% as of last week.” Production Team:“What’s your goal?” Yoon Si-yoon:“5%. They say you need to hit 5% for visible six-pack abs.” MC Seo Jang-hoon compares it to singer Kim Jong-kook’s 9% and Cristiano Ronaldo’s 7%. Despite already losing 10 kg, Yoon continues daily workouts to reach 5%. He runs intensely for 30 minutes without rest. 8:20 AM – Personal Training (PT)During PT, he gives powerful shouts, revealing defined muscles and visible six-pack abs. Breakfast in 20 Minutes 9:00 AM – Back HomeAfter showering, he applies lotion while admiring his muscles in the mirror. Another alarm. 9:40 AM – Breakfast TimeWith a 10 AM schedule, he has only 20 minutes to cook and eat. He quickly prepares two dishes: Everything is done swiftly and neatly. He finishes eating in 8 minutes and immediately washes dishes in 2 minutes. Another alarm. Always Preparing – English & Japanese Lessons 10:00 AM – English Lesson (Phone Conversation)He practices speaking English related to an upcoming drama role. Yoon Si-yoon:“One day, my mom handed me two random English books. I asked, ‘What is this?’ and she said, ‘You’re on TV but your English is terrible.’ I felt ashamed. I had so many great opportunities but missed them because of language. I regretted it so much. I told myself I’ll get another chance, and I have to be ready.” His study room is packed with English books. After an hour, his next lesson begins. 11:00 AM – Japanese Lesson (Phone Conversation)He steadily prepares for future opportunities by learning Japanese. Back to Acting – Character Study & Practice 12:00 PM – Acting PracticeIn his home theater, he watches dramas, eats salad, pauses scenes to take notes and mimic the characters, repeating the process. Even Rest is Regulated 1:00 PM – Game TimeHe enters his game room for the first break of the day. Just 15 minutes in, the monitor shuts off. Yoon Si-yoon:“If I don’t limit game time, it never ends. I preset the monitor to turn off after 15–20 minutes.” Even his rest is planned and limited. Outfit Planner – Planning a Month of Outfits He heads to his closet, where clothes are neatly sorted by color and type. He lays out outfits for June, referencing style photos he discussed with his stylist. Every outfit—casual to TV appearances—is preplanned. Production Team:“Are you into fashion?” Yoon Si-yoon:“No, I was once picked as a worst dresser. I just want to try different looks in my 40s. I’m not confident, so I plan a whole month of outfits in advance with my stylist.” His favorite accessory? Pearls. Everything—black jumper, white shirt, leather jacket—is matched with pearl necklaces. After trying on outfits, he documents each look on a calendar. His goal is clarity and confidence in his style.

Actor Yoon Shi-yoon’s Extreme Self-Management Revealed on SBS’s “My Little Old Boy”

Actor Yoon Shi-yoon first gained recognition in 2009 through the MBC sitcom “High Kick Through the Roof.” While he became known through this work, he wasn’t quite what one would call a “star” yet. He earned the title of “star” after appearing in the KBS 2TV Wednesday-Thursday drama “King of Baking, Kim Tak-gu.” He played the lead role of “Kim Tak-gu” in this drama, which achieved an astounding 50% viewership rating, propelling him to top-star status overnight. A 50% viewership rating is now virtually impossible, as changes in the media environment mean even 10% is considered a huge hit. Since “King of Baking, Kim Tak-gu,” Yoon Shi-yoon has been recognized as a star. Now, Yoon Shi-yoon has joined the cast of SBS’s “My Little Old Boy.” Born in 1986, he is now 40 years old in Korean age, or 456 months old. Given that the show features single men who have passed the typical marriageable age, he certainly qualifies to appear. While he was frequently seen during his time on KBS’s “2 Days & 1 Night,” he has only occasionally made appearances on variety shows since. However, this is his first time appearing solo for about an hour, and more importantly, it’s the first time he has shown his home and private life, which has garnered significant attention. On “My Little Old Boy,” Yoon Shi-yoon showcased his daily routine. His way of life was quite unique. His star power, combined with his peculiar lifestyle, captivated viewers’ interest and curiosity. His day, as shown on “My Little Old Boy,” began and ended with alarms. He had alarms set for every hour, meticulously dividing his day. Let’s list his activities from waking up to falling asleep, in chronological order: The Alarm King – Dividing Time by Minutes 7:00 AM: Wake Up. At 7:00 AM, the lights in Yoon Shi-yoon’s bedroom automatically turn on, and an alarm rings. He immediately gets up and prepares a protein shake for breakfast. As he prepares his meal, he promptly tidies up any items he uses. Another alarm rings while he’s making the protein shake. 7:03 AM: Protein/Supplements. He precisely drinks his protein shake and takes his nutritional supplements on time. Then, the alarm rings again. 7:07 AM: Vocal Practice. As an alarm rings for every action, an interview with the production crew follows. Yoon Shi-yoon: “I usually set alarms to plan my next day’s schedule. I have a monthly plan and a weekly plan as a basic framework, and then the day before, I plan what I need to do and set alarms. I have to set it up like, ‘At this time, do this; at that time, do that.’ There’s only one reason for that: if I don’t set it up, I’m afraid I’ll go out and play aimlessly. I’m so scared of becoming lazy. I’m an incredibly lazy person, so I can’t do without a plan. Really. Truly.” Production Crew: “Do you get anxious if the timing isn’t kept?” Yoon Shi-yoon: “I get uneasy. Because the plan goes awry. I think I’m most comfortable when I live according to a plan. I get energy from that.” He sets alarms daily to avoid becoming lazy and lives as a meticulously planned individual. Even while doing vocal exercises, he immediately washes the cup he used. He lies by the living room window, enjoying the Han River view, and practices vocal exercises while lifting his back and stretching his feet. Another alarm rings. He runs towards the gym. The Body King – Aiming for 5% Body Fat 7:50 AM: Gym Running. Upon arriving at the gym, he immediately starts running. An interview with the production crew follows. Production Crew: “You seem to have lost a lot of weight?” Yoon Shi-yoon: “I’m preparing for ‘Taxi Driver 3.’ I’ve conceived the character to be very gaunt, almost emaciated, so I’m controlling my weight.” Production Crew: “What’s your current body fat percentage then?” Yoon Shi-yoon: “Last week when I measured it, it was about 6.5%.” Production Crew: “What’s your target body fat percentage?” Yoon Shi-yoon: “5%. They say if you want to get a six-pack, you need to get it down to around 5%.” Upon hearing this, MC Seo Jang-hoon points out that singer Kim Jong-kook has 9% body fat and soccer player Cristiano Ronaldo has 7%, making Yoon Shi-yoon’s goal seem incredibly impressive. Despite having already lost 10kg for his role, he continues to exercise daily to reach his 5% body fat target. He ran continuously for 30 minutes with high-intensity running. 8:20 AM: Personal Training. Throughout his PT session, he lets out shouts of effort, and his lean muscles are visible. When he exposes his abdomen during exercise, a clear six-pack is evident. Breakfast in 20 Minutes 9:00 AM: Return Home. After showering, he applies lotion to his upper body. His six-pack and all his body muscles are visible. He seems satisfied as he constantly looks at himself in the mirror while applying lotion. Another alarm rings. 9:40 AM: Breakfast. Due to a 10:00 AM appointment, he has to finish cooking and eating within 20 minutes. His breakfast ingredients are black rice and tilapia (a high-protein fish). He quickly fries the tilapia in a pan, preparing it with practiced speed and precision. After grilling the fish, he sprinkles parsley and garlic flakes to create his first dish, “Grilled Tilapia.” He then starts on his second dish, adding water to black rice and stirring in green tea powder. He greases the pan again and grills low-sodium pollock roe. He then places the grilled roe on the black rice. His second dish is “Low-Sodium Pollack Roe Ochazuke.” He completes his breakfast at lightning speed. After cooking, he immediately soaks the used pan in water and wipes down the gas stove. Now, he begins to eat. 9:50 AM: Breakfast. With limited time, he mixes the fish with rice and eats it hastily with a spoon. Later, he eats the protein (fish) first. He constantly checks the time while eating. Eventually,
