That's honestly where the show really shines. The motivational aspect of it, really makes you wanna train and if you ever practiced any of the disciplines in the show, you somehow appreciate it even more. Kinda has that Ippo vibe in a sense. Plus the villains help him bring out a different part of his training, as if they're apart of his growth as well.
