Training arcs are understandably viewed with skepticism whenever they occur in shonen. cartoon simply because the demographic tends to rely too heavily on them to explain how a hero becomes exponentially stronger against a stronger opponent. However, Viral Hit The anime is showing how it's done, and the series isn't even shonen, let alone Japanese. It's manhwa. Incredibly, the series even has the main character, Hobin, go through even more training than the shonen series that are considered the worst offenders in this regard, and the entire premise of Viral Hit really justifies this higher amount.
Hobin is actually quite weak and is even considered a “normal” person as opposed to a real warrior. The reason why Hobin has to constantly train is because he is in a unique situation where he can quickly earn a decent amount of money by fighting off bullies It was then streamed on the show's YouTube equivalent.
Especially since he is not a natural born fighter, Hobin is yet and has the ability to will never meet an enemy whom he can defeat by relying only on his current knowledge, so he has to practice all the time. Hobin's practice form happens to be a channel on the same social media platform that happens to post videos explaining how he can win every match.
Viral Hit's formula combines the Shonen action genre with a mainstream
In essence, Viral Hit's unique format makes it more similar to a martial arts/boxing manga like Hajime No Ippo, except Viral Hit provides an extra element of drama as Hobin can't benefit from the extra guidance and support system that comes with fighting in a legitimate sport with rules. The similarity is that, in boxing, it doesn't matter how good each fighter is. Each fighter must constantly train their body and adapt their fighting style to their opponent, essentially honing themselves into the perfect weapon for that particular match. Every match is different in this regard, and that's exactly the case with Viral Hit.
However, Viral Hit adds even more variables to Hobin's training, beyond the fact that he's not a professional fighter. For example, he has to fight many fighting styles that he's not familiar with, like taekwondo, and, in his latest case, multiple opponents at once. A lot of the training he goes through is also unusual, especially when compared to professional sports, as he's allowed to incorporate the environment into his fights in some cases.
Furthermore, Hobin even reuses some of his training regimens to use them in ways that have never been used before, another common aspect of shonen. There's even a fun and naturally mysterious fact involved, that Hobin's trainer is an anonymous individual who wears a rooster mask for some reason.
Practice arcs in any series can be overused in shonen, to the point where most series include multiple practice arcs in a short period of time, but anime adaptations of manhwa Viral Hit not only justifies their use, but does so by adding more of it to almost every other episode to great effect.
