The manga that inspired the new anime: a series about beautiful girls getting buff!
Sakura is a teenage girl who loves to eat, but when she notices her waistline expanding, she decides to check out the local gym. The gym is full of buff dudes…and Akemi, the student council president?! When Akemi tries to convince Sakura to take up weight training, Sakura resists–until she meets pretty-boy trainer Machio. Now, Sakura is willing to do whatever it takes to bulk up!
