I always welcome more titles incorporating active exercise! There aren't that many series apart from the "Dumbell" series and Muscle Joseon, you can imagine my excitement at another title. After breezing through the 17 chapters, this series is good but it can't be more than that. The story just centers around a regular weak-willed MC who gets exposed to exercise by a cosplaying idol (by coincidence). She teaches him to get fit to help her with cosplay....yeah plot in a nutshell. The range of exercises is decent, I recognize a good number of them, and some I even did in the past. The flaw lies with the MC, I find himunreliable. Not as lame as Kazuya but it's beginning to seem like it. The ONLY reason he started to take weight loss seriously is because of the girl. It is proven dead that he would never have embarked on this journey of exercise if he had not met the girl. Several chapters in, you can see his lust is stronger than his will to get fit.

Sadly the only redemption for this series can happen if the MC takes fitness seriously and not only for the girl.
Who knows? There aren't that many chapters out yet, so let's keep up.
