Hibiki Sakura is a second-year high school student who attends Koyo Girls’ Academy and absolutely loves food, especially junk food. But when her best friend Ayaka Uehara points out how she is gaining weight, she reluctantly decides to shed some pounds by joining the local gym, Silverman Gym. There, she meets the beautiful Akemi Soryuin, a popular classmate of hers with a serious muscle fetish, who is also thinking about joining in order to live a healthier lifestyle. However, Hibiki quickly becomes intimidated by the sea of muscular beefcakes in front of her and is just about to leave when she meets one of the trainers at the gym, Naruzo Machio, and falls head over heels for him. With renewed motivation to go from flab to fab, she begins her quest to develop the perfect hot bod in this sports comedy manga by Yabako Sandrovich and MAAM!
In Vol. 5, Hibiki enters a punching machine contest where she absolutely crushes it and wins, drawing the attention of movie star Harnnold Dogegenchonegger. Later, spring break arrives, but instead of relaxing the girls head to the gym to train, and Hibiki begins working on her abs.
