Why heroes are physically stronger than average humans In the world of My Hero Academia, the human society acquired Quirks.

So basically instead of having regular humans, we have humans with abilities.

With the exception of Power-Up quirks (like one for all...etc), why do humans/heroes/villains seem physically stronger?

I mean, they can go through walls and be smashed on the ground and still stand, with minor injuries, training can't make a human sustain such things..

In One Piece for example we know the world is filled with abnormally strong humans, but that's not the case in My Hero Academia, is it??

Bakugo standing up after Deku's power-up punch, even with 8% it can make holes in walls, why didn't it kill bakugo?
In a lot of anime, humans just have more durability than real-life humans. Not sure how I'm supposed to provide sources for this, but in, for example, One Punch Man, Saitama was repeatedly beaten down by Crablante before gaining any powers and survived. In JoJo Battle Tendency, Mark gets half of his head sheared off and is still able to talk for a while after. It's just a common thing in many anime that humans have higher-tier durability than their real life counterparts. I wouldn't pay much attention to this.
