A pianist who loves both piano keys and computer keyboards, I spent 10 years in the IT education industry after learning to program. For some reason, I now live my life as a CrossFit coach and restaurant manager, while still playing the piano from time to time.

After working 🔥relentlessly🔥 in the IT industry for 10 years and experiencing my body breaking down firsthand...
I'm now Kim Seulgi, a current CrossFit coach who teaches people healthy movement.

  • Before I started moving my body, there was always a low-frequency therapy device at my desk in the office...

  • When you work hard, your back, shoulders, or somewhere starts to feel uncomfortable...

  • When it got bad, even my legs would go numb, and I'd toss and turn endlessly before finally falling asleep from exhaustion—that was my daily routine.

I don't think this is just my story 🥹 Sure, signing up for personal training? Starting running like everyone's doing these days? All good, but they require too much commitment. Let's just gather online in the evening and move around, even if it's light. Definitely something will change.

😄 These people are welcome!

  • Sitting in front of a computer for 4-6 hours or more per day!

  • People who are best friends with orthopedics and pain clinics because of aches and pains everywhere (at least your medical insurance claims are solid...!)

  • People who want to refresh comfortably in the evening


📅 Challenge Details

  • Period: [Mon, Wed, Thu] between Jan 26 (Mon) ~ Feb 27 (Fri), 2026
    - We'll take a break during the Lunar New Year holiday!
    - Surprise additional stretching sessions may be added depending on the coach's schedule!


  • Time: Every night at 9:30 PM (expected to be around 20 minutes at most)

  • What you need: A light body and a computer! (Online session using Google Meet, etc.)


Those who've experienced the pain firsthand know better 🥹 In 4 weeks, or actually even just one week of consistency, you'll be able to feel something change. Let's get healthy together right now!

    Lately, the weather has been cold and I've been feeling lazy, so my daily routine was just lying down as soon as I got home from work. When I first discovered this challenge, the concept felt so fresh, and I signed up on a whim thinking, "It's better than doing nothing." Before I knew it, I ended up receiving 1:1 online fitness coaching from Coach Seulgi. Since I was the only participant, I was a bit worried at the beginning that the challenge might be canceled midway. However, it was carried out fully for 4 weeks, 3 times a week, without missing a single day! My room was such a mess that I couldn't bring myself to turn on the camera... so I couldn't show my movements to the instructor. But even before I could wonder, "Am I doing this right?" the instructor pointed out the specific details to focus on for each movement and asked me first how each part of my body felt. Thanks to that feedback, I was able to move with confidence in my own way. In the beginning, we used Google Meet a few times due to audio quality issues (which turned out to be because I was accessing it via mobile web). However, for the live sessions held on Inflearn, recordings were available, which was very useful for reviewing the movements I learned, and I think I'll refer back to them often in the future. Thanks to the instructor, I was able to experience various stretching methods for different parts of the body! In particular, the hand and upper body stretches/massages were quite painful every time, making it feel like I was torturing myself... but it made me realize how much I had neglected those areas until now, so I plan to do them more often from now on. Also, the dog that occasionally appeared during the sessions was so cute! I was happy to see it again on the last day haha. Coach Seulgi, thank you for leading me so well so that I could complete the challenge until the end, and thank you for sticking with it too. I hope to see you again if the opportunity arises!

      Hello! Thank you for your thoughtful review. As you mentioned, the existence of this kind of challenge on Inflearn is quite fresh, and I can understand why you might have hesitated. Thank you for taking the courage to participate. I also didn't expect to end up doing intensive 1:1 coaching (haha). To be honest, I did contemplate whether to go through with the challenge, but I didn't want to let go of even a single person who had made up their mind to say, "I should try working out!" Reading your review, I'm relieved to hear that it was helpful in various ways despite my shortcomings. Thank you for participating so diligently without ever being late. I hope this challenge serves as a great start to your new fitness journey, Elio... Let's stay healthy!🍀 See you again!
