“Extreme Self-Discipline” and “A Thoroughly Planned Life” Reflected in actor Yoon Shi-yoon’s Words

Actor Yoon Shi-yoon’s daily routine shown on Same Bed, Different Dreams 2 left a strong impression. He allows no gaps in his life in order to become a better version of himself. He plans everything in advance and checks every schedule with alarms. The reason he manages himself so thoroughly becomes clear through his conversations on the show. “I feel most comfortable when I live according to my plan” — A day that starts with alarms 07:00 Wake up 07:03 Protein & supplements 07:07 Vocal warm-ups Every action from the moment he wakes up is signaled by alarms. Yoon Shi-yoon: “I set alarms and plan the next day’s schedule. I usually establish a monthly plan and weekly plan, then decide the next day’s tasks the night before. I need to assign time slots—what to do at what time. Why? Because if I don’t, I might go out and waste time meaninglessly. I’m terrified of becoming lazy. I’m actually a very lazy person, so if I don’t plan things, it doesn’t work. Really.” Producer: “Do you get anxious when time isn’t kept?” Yoon Shi-yoon: “I feel uneasy. The plan gets disrupted. I think I’m most comfortable when I live according to plan. I get energy from that.” Heading toward 5% body fat 07:50 Gym – Running He begins running as soon as he arrives at the gym. Producer: “You look like you’ve lost a lot of weight.” Yoon Shi-yoon: “I’m preparing for Taxi Driver 3. I imagined the character looking gaunt—almost skeletal—so I’m controlling my weight.” Producer: “What’s your current body-fat percentage?” Yoon Shi-yoon: “Last week, it was around 6.5%.” Producer: “What’s your goal?” Yoon Shi-yoon: “5%. To really make the six-pack visible, they say you need to drop to around 5%.” MC Seo Jang-hoon mentions that singer Kim Jong-kook is at 9% and Cristiano Ronaldo stays around 7%. Despite already losing 10kg for the role, Yoon Shi-yoon works out daily to reach his 5% goal. “I hate seeing things exposed” — The ultimate level of tidiness – Stovetop covered with a custom-made lid – Power outlets hidden behind covers – Sink without a single dish – Kitchen entirely concealed or neatly stored – Identical containers in each fridge compartment – Labeled produce in the vegetable drawer – Labeled items in the freezer – Post-its tracking ingredient usage Yoon Shi-yoon: “If you just leave ingredients in the fridge, you can’t manage them.” Producer: “Is this influenced by the military?” Yoon Shi-yoon: “I felt joy when organizing things during my time as a Marine. Haha.” “I believed opportunities would come again, so I had to master languages” — English & Japanese 10:00 English lesson (phone call) He discusses preparing for a new drama. Yoon Shi-yoon: “One day my mom suddenly handed me two English textbooks. I asked her, ‘What is this?’ and she said, ‘You’re on TV, but your English is too bad.’ I felt so pathetic. So many staff members are filming me, and I need to interact comfortably with foreigners, but… what have I been doing with my life? Why was I so lazy? I regretted it deeply. I was ashamed. I missed so many great opportunities because of language. I believed opportunities would come again, so I had to master languages.” His living-room shelves are filled with English books. After one hour, the English lesson ends. 11:00 Japanese lesson (phone call) He studies steadily for opportunities that he believes will eventually come. “If I start gaming, I can’t stop” — 15-minute gaming rule 13:00 Gaming time He enters his game room with consoles, retro games, and comics. It’s his first break of the day. But suddenly, the monitor turns off. Yoon Shi-yoon: “If I start gaming, it never ends, so I have to set a time limit. After 15–20 minutes, the monitor automatically turns off.” His rest time is exactly 15 minutes — another form of self-discipline. “I want my wardrobe to look like a clothing store” After gaming, he moves to the wardrobe inside the game room. Clothes are sorted by type and color. Yoon Shi-yoon: “I want my closet to be in top condition, like a shop display. To do that, I can’t have too many clothes. They can’t overlap. There’s a maximum number of hangers allowed. If I run out of hangers, I sort and remove clothes.” Planning a full month of outfits in advance He takes out his clothes and accessories and begins planning June’s outfits. The May calendar shows photos of daily outfits, including days off. Producer: “Are you interested in fashion?” Yoon Shi-yoon: “No. I was even once selected as a worst-dressed celebrity. Now that I’m in my 40s, I want a style change, but I have no sense of fashion and no confidence. So I consult a stylist, prepare a month of outfits, and follow the plan.” “Washing my car makes me feel calm” He drives to a self-car-wash station. Yoon Shi-yoon: “Washing my car calms me. It feels like I’m bonding with it through the machines. I wash it at least once a week.” He puts on a jumpsuit, then an apron, then headphones to block noise and enjoy music. He unloads countless car-wash tools and organizes them neatly: – Cleaning brushes – Pressure sprayer – Pre-wash detergent – Car shampoo – Tire cleaner – Tar remover – Oil-film remover – Polish 1 & 2 – Interior coating – Leather conditioner – Tire shine – Multiple microfiber cloths MC Seo Jang-hoon says even professional car washes don’t go this far. Yoon Shi-yoon: “I think I just love cleaning. I get excited seeing dirt, because I know I can clean it. I use hot steam, melt it down, wipe it… and watching it become clean is so satisfying.” It takes two hours just to clean the exterior. He says interior cleaning would take an additional two hours. The white car looks new — but it’s 12 years old. “I’m terrified of becoming lazy” After showering, he plates three pieces of finger

Yoon Si-yoon: “I set alarms and plan the next day in advance. I always make monthly and weekly plans, then finalize the next day’s schedule the night before. I have to decide exactly what I’ll do at every hour. Why? Because if I don’t, I’m afraid I’ll end up wasting time outside. I’m terrified of becoming lazy. I’m actually a very lazy person, so unless I set plans, I can’t function. Really. Truly.” Staff: “Do you get anxious when you fall behind schedule?” Yoon Si-yoon: “I get nervous. Things fall apart. I feel most comfortable when I live according to plan—that’s where I get my energy.” 07:50 — Intense Workout & Body Fat Goal Upon arriving at the gym, he immediately starts running. Staff: “You seem to have lost a lot of weight.” Yoon Si-yoon: “I’m preparing for Taxi Driver 3. I want my character to look extremely gaunt, so I’m controlling my weight.” He shares that his body fat last week measured 6.5%, and his goal is 5% to achieve a clear six-pack. MC Seo Jang-hoon notes that singer Kim Jong-kook is 9% and footballer Cristiano Ronaldo is around 7%. Yoon has already lost 10 kg and continues training intensely every day. A Kitchen Hidden for Perfect Order His kitchen is arranged with extreme minimalism: A custom-made cover hiding the gas stove Hidden electrical outlets A sink with no visible dishes All kitchen items concealed or stored Identical containers arranged by rows and columns Labeled vegetables and frozen ingredients Post-its tracking ingredient usage Yoon Si-yoon: “If I just leave ingredients in the fridge, I lose control.” Staff: “Is this influence from the military?” Yoon Si-yoon: “In the Marine Corps, I actually felt joy when organizing.” 10:00 — English Class / 11:00 — Japanese Class He takes English conversation lessons by phone, discussing preparations for his new drama. Yoon Si-yoon: “One day my mom gave me two English textbooks. She said, ‘You’re on TV but your English is too poor.’ I felt ashamed. So many staff members work with me, and I couldn’t communicate well with foreigners. I regretted how lazy I’d been. I believed another opportunity would come someday, so I decided I had to master languages.” His bookshelf is packed with English books. After an hour of English, he immediately moves to a Japanese conversation class—preparing for any future opportunity. 13:00 — Game Time (Strictly 15 Minutes) He enters his game room filled with consoles, retro systems, and comics—finally a break. But the monitor suddenly turns off. Yoon Si-yoon: “Gaming can go on endlessly, so I set a time limit. After 15–20 minutes, the monitor turns off automatically.” Even leisure time is strictly controlled. Closet Organized Like a Boutique Inside the game room is a walk-in closet where clothes are sorted by type and color. Yoon Si-yoon: “I want my closet to look like a boutique. That means I can’t own many clothes. If the hangers aren’t enough, I declutter.” He prepares his June outfit plan, laying out clothes and accessories. His May calendar is filled with photos of daily outfits—every look planned in advance. Staff: “Are you into fashion?” Yoon Si-yoon: “Not really. I was even selected as a worst-dressed celebrity once. But now in my 40s, I want to try new styles. Because I’m not confident, I work with a stylist to prepare a month of outfits in advance.” Weekly Car Wash Ritual — 2 Hours of Precision He drives to a self-service car wash. Yoon Si-yoon: “Washing my car calms me. Using big machines feels like talking to the car. I go at least once a week.” He changes into a jumpsuit, then adds an apron and noise-canceling headphones. His car wash supplies are meticulously organized: – Multiple cleaners, shampoos, brushes, steamers – Leather conditioners, waxes, microfiber towels – Every tool lined up neatly in rows Seo Jang-hoon comments that even professional garages don’t wash cars this meticulously. Yoon’s car, now 12 years old, looks brand new thanks to his care. Dinner: Smoky Whiskey Pairing Without Drinking After showering, he prepares three pieces of finger food and whiskey. Using wood chips and a dome, he infuses smoke into the drink. Yet he only smells the whiskey or touches a drop to his tongue with a pipette. Yoon Si-yoon: “Robert Downey Jr. only smells whiskey while filming, so I tried it. It works. When managing weight, alcohol is more harmful than food. I’ve avoided alcohol for six months, and that’s when my body fat finally dropped below 10%.” Digital Detox — The “Self-Control Box” He takes out a “self-discipline lock box” where he locks his phone before bed. Yoon Si-yoon: “If I look at my phone at night, dopamine keeps me awake. Suddenly it’s 2 a.m. So I lock the phone away.” At 10:00 PM, with his sleep mask on, he ends his extremely structured 15-hour day—a level of discipline nearly impossible for most people. Yoon Si-yoon: “I’m scared of becoming lazy. I’ve received so much love and opportunities at a young age. If I live recklessly, I feel guilty. So I push myself while comforting myself, always trying to improve.”

“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.
