Due to a large volume of summer casual trainers at the gym, Hibiki and Akemi aren’t able to access the “free weights” like the bench press and dumbbells, so on Machio’s advice they train instead on machines like the chest press machine, which are a good way to diversify the way one exercises a muscle group.
Ayaka also joins the gym to give boxing classes, and is as immediately smitten with (a fully clothed) Machio as Hibiki and Satomi were…before he struck his signature “Side Chest!”, that is.
The first day Hibiki, Akemi and Ayaka meet up to go to the gym as a trio, Silverman is unexpectedly closed for the day. While they lacked their primary training equipment at the gym, not having access to a gym at all means getting more resourceful.
Akemi invites the other two to her palacial house, and shows them a beefcake-packed video by Ozu Toshio, apparently Machio’s sensei. They learn reverse sit-ups and dips using chairs, but unfortunately when Hibiki ups the difficulty by attempting dips with a backpack full of books, she breaks two antique chairs she later learns could sell at auction for hundreds of millions of yen. Oops!
Finally, the three girls (plus Satomi, in another case of pure coincidence) hit the beach to show off their tight new bods, only to learn the summer swimming season is closed due to hammerhead sharks in the water.
Not one to be discouraged by a setback, Akemi shows the others how to do burpees, which exercise the entire body (which she proceeds to expose in the instructional video), followed by sprints along the beach. While everyone gets properly worn out by day’s end, everyone rightly feels a great sense of accomplishment. Who needs gyms, or even the sea, when you have a nice stretch of sand?
