Originally for the thumbnail and ended up binging to the latest chapter. Sadly it got axed at chapter 132 due to lack of interest and popularity. Yes it's a Korean Isekai story but a brilliant take on bodybuilding/exercise in a historical era. I believe this is the only Manhwa that is able to make a series in old Korean Era fascinating. The MC himsefl is a decent young adult who majored in nutrition with body building as a hobby. So after becoming a past figure in the new world, he decides to create a revolution with exercise. If anything, this Manhwa is top tier with well craftedexplanations, details, exercise implementations all around. The time passage is a little fast but respectable. You don't even have to be a body buiilder to keep up with the story. Though it will remind me deeply about the importance of exercise.

It's not peak, the long term story does become long drawn and more...political? It can't compete with the Manhwa Headliners, so the ending must be accepted even if it's not ideal
