Well- new to us anyways. We're diving into working out. Yes, that's right, a whole ass anime about working out. Somehow Japan really knows how to make boring or strenuous things pleasant and entertaining. Anyways, enter Hibiki Sakura, our main character of this story. She's a high school student that has put on some 'weight' and freaks out about it and decides to make a change. Going to the gym. NOT JUST ANY GYM THOUGH. Silverman's gym where she runs into a fellow classmate, Akemi..who is more than in love with muscles..she's obsessed. With the direction from personal trainer, Machio -who is really weird on his own- the girls learn the best workouts for their goals!
