Read Ijiranaide, Nagatoro-san Ch. 141 "I'm... I'm fighting for myself and for senpai!!" on MangaDex!
And that is the fight over with! I think it is funny that the flashback she had at the climax to give her the strength to overcome was when she was in the hot springs with Senpai.
Having done judo for more than a decade, that's pretty unrealistic. Orihara would have switched position instead of standing still.
The thing is that at those levels your body reacts before you even have a chance to think. That is why you practice every move you learn thousands of times; it becomes muscle memory.
Yeah, I wrestled for years and years and I agree. This is one of the main reasons I don't really partake of any sports-focused anime/manga. Having done many sports, it is too hard to suspend my disbelief. As I have gotten older, I now run into the same issue with a lot of science-heavy stories since I work professionally in the sciences.
