Depends on what you call big. Modern depiction of Hercules and Achilles don't display them as overly big.
And if you go into the superhero world, the super strong supes that aren't clumsy have been skrinking in muscle mass.
And let's not get into the budding East Asian, Western style fantasy market. Warriors coming from Japanese, Chinese, and Korean artists are thin.
And if you get into Western T and Film, strong men are often not huge do to needing real human actors. They're muscular but no way bodybuilder status like before. Then you have trends of them fighting with or against women. Since everyone doing have an Amazon fetish, you get men in strength matches with women and not auto winning.
Not that I'm saying people don't see a correlation with size and strength at all. I'm saying it;s combined with dexterity/agility. I would guess that people under 40 would see a very big person as stronger and clumsier. It's hand and hand.
So the choice would to be:
- Let it as is
- Make the Big characters both stronger but clumsier.
So, back to the point you made, which I think you are (correctly) clarifying.
There is a correlation between size and strength. Still, and obviously. In fantasy. In modern fantasy. However you want to put it, and however elastically you define the terms. It's a normal visual cue that someone has gotten "stronger" by getting "bigger" and always has been- from Bane to Hulk (superheroes); and Hercules is almost always depicted with a large physique:
Schwarzenegger, Sorbo, The Rock, and so on. Hardly small guys! Even "Young Hercules" was played by a pretty buff Ryan Gosling.
But I do agree with you that there is a premium on dexterity and agility. It's just not .... new. The idea of the protagonist defeating the bigger, stronger baddie with agility and smarts is as old as time. It's appearance in movies predates even Errol "Not a BodyBuilder" Flynn's swashbuckling.
So .... yeah. Not sure where your original statement came from.
