How Heavy Are the Dumbbells You Lift?

ダンベル何キロ持てる？

Hibiki Sakura, a gluttonous second-year high-schooler, notices her waistline expanding and decides to join a gym — only to discover that Silverman Gym is also attended by her school's prim honor student, Akemi Sōryūin, who turns out to be a closet muscle fetishist. Under the tutelage of the absurdly sculpted trainer Machio Naruzō, each episode teaches a real exercise (bench press, squats, planks) through Hibiki's comedic attempts, while an expanding cast — including their history teacher Satomi Tachibana and the Russian exchange student Gina Boyd — joins the fitness journey.
