That's the kind of twist that's expected from this manga. Also expected from the chapter title.
It's not that extreme, but working out does have a lot of benefits.
I wouldn't quite agree with her, but she's right.
Workout is something you do in moderation and after ability. If you push yourself to that extreme, you're doing it wrong.
You're going to have to work out quite a lot with a specific schedule and diet to get muscles that noticeable. Unless you have the genes for it, but then you'd probably already have a decent frame.
The signs around her are wrong. There's nothing unexpected about her adorability, and I'd question the "a bit" part about being a tsundere.
"Which part about this can you call beauty..."
Get a mirror. Kinda funny saying that after a 2/3 spread illustration.
I'm not sure a 6% increase is significant, unless they have a large enough sample size. If they were just using students, then no. If just her, then lol no.
Wonder what exercise she did to have her thighs hurt.
Why is she exercising in a dress
All she owns? Doesn't seem like the kind of person who'd even own sports clothes.
What I wonder is why she has her stockings on. I mean, other than for fanservice.
