Translators note: I was overthinking whether or not to use slang like "lats" bc just because someone uses the full Japanese name of the muscle doesn't necessarily mean it sounds as fancy as if someone did that in English... Unless it does, this is not something I have encountered a lot ... I ended up erring on the side of putting verbatim whatever my JP-EN dictionary says, with a Wikipedia link in case you're like me and don't know what a lat is anyway

Yuki Ueno: My sternocleidomastoid muscle! It's a muscle in the front of the neck, and I've been able to build up a neck that can minimize damage from a match. A thick neck is a symbol of vitality, plus it makes your face look cute and small.

Kaisei Takechi: Right now, I might not have a particular part of my body I can say "Look at this!" about. Now that I'm a pro wrestler and I've experienced for myself that there's always someone greater, I'll train harder and work hard to have something I can be proud of!

Chris Brookes: 201 cm! My height is my greatest pride! (Though it's just luck so I don't really have the right to be proud of it...)

Konosuke Takeshita: I don't have any muscles I'm proud of yet. I'm a novice after all.

Takeshi Masada: My biceps brachii. That's one of the first muscles you think of, after all, so I work hard on them every day because I want to be able to be proud of them.

Kanon: My back, especially my latissimus dorsi! I've raised them with special care and daily pull-ups lol

Mao: My shoulders and how wide they are! They're the source of my foundational squareness.

Kazuma Sumi: My back, I think. It's easier for me to put on muscle there than the rest of me.

Yuya Koroku: The gluteus maximus is the biggest muscle in the body and I have a lot of confidence in mine! When I measured them recently they were 102cm!

Shunma Katsumata: My arms and shoulders, all around there! Because everyone always praises them ^^

To-y: My triceps! They're big and bulging so I have a lot of confidence in them!

Hinata Kasai: My shoulders! That's what I've gotten the most praise for.

Yuni: My shoulders. Lots of people have told me I have wide shoulders.
