Anime de Training! Ex

Asami, Eri, Yū, Shizuno, and Shion are all cleaning up the new apartment "Bonheur Chateau", with the viewers helping out, in order to start their new lives together. During their clean-up time, Asami teaches the viewers the lateral side bend exercise in the lesson room. Then, a mysterious new girl arrives in front of the apartment.

Eri, while heading for school, teaches the viewers the invisible chair and calf raises, in a train. Afterwards, she introduces them her friend, who thinks Eri and the viewers are a couple. Soon after, they unexpectedly encounter Shion, who is working at her station while trying to hide her secret from them.

Shizuno helps Yū do the Mat Exercises, while they both teach the viewers the two kinds of Mat Exercises: The Somersault and the Somersault Splits, in order for Yū to do well in her Mat Exercise Test on the next day.

Shion teaches the viewers the Supine Hip Lift and the Sit-ups, while trying to make them believe that she doesn't work at the station, even though she does. Soon after, she gets her message from her mother, and when her mother arrives, she gives the pizza that she bought to the viewers, to give to Shion, much to Shion's dismay.

Back in Shizuno's indoor pool, Asami was about to train for her swimming competition at school, until Shizuno suggested that she needs to do her warm-up stretches. Shizuno then helps Asami warm-up, while they both teach the viewers how to stretch by doing the front and back bends, the invisible chair stretches, and the leg raise stretches.

Sakura Izumi, the new girl from before and who thinks she is an emperor from "The Sakura Empire", teaches the viewers, while treating them as her "noble steed", the Ball Sit-ups and the Wide Squats, even though she tried to cheat her way out of those exercises.

Asami and Eri teach the viewers how to jog, and during the jogging montage, one policewoman, three little girls, and a cat all jog along after Asami and Eri stopped by. Soon after, Asami, Eri, and the rest of the girls enjoy their bath time, while Eri gets more jealous when she notices that Asami's breasts grew a little more bigger.

After witnessing that Yū was jogging like Asami and Eri did, Shion massages her leg to relax. Then, Sakura appeared, and while teaching and massaging the viewers, Sakura and Shion fought over Yū. When the other girls arrived to see them fighting, Yū was left no choice but to play along and becomes an evil wizard, apparently.

Shizuno teaches the viewers how to warm up by rope skipping, both normally and crisscrossing. During the exercise, she talked about her life and having fun exercising with her friends. After they finished warming up, and Andalucía tied Shizuno up and made her fall on the viewers, they all enjoy the tea made by Shizuno.

Yū was concerned about using her contact lenses rather than her glasses, so in order to relax, she does, while teaching the viewers, the Unilateral Push-ups and the Prawn Back Extension. Afterwards, she accidentally bumped into Shion, making Yū drop her contact lenses, which are broken accidentally by Sakura soon after.

Asami teaches the viewers how to work out with dumbbells. Soon after, a Christmas party is coming up, and Asami got something to say to the viewers for later. However, she is not the only one, because Eri, Sakura, Shizuno, Shion, and Yū have all got something to say to the viewers as well.
