Not necessarily
On the topic of her massive arms, for a while, Abby's enormous physique bothered me, as it seemed way out of place in a post apocalypse wasteland. It ended up being one of the more effective aspects of the game, as her physique was used narratively.
I can't remember how far into the game it was, but there's a point fairly early on where you play as Abby, and you're at a military base. At one point there, you get to see the resources this military has at its disposal. All of a sudden, it wasn't so strange to have a big, beefy lady with an equally big beef and lots of beef.
It destroyed the notion of a post apocalyptic wasteland to some extent, but that's kind of fitting, given that both Abby and Ellie live in rebuilt micro societies that are two key components of our current, not-completely-apocalyptic society: military and civilian. They also both shun those societies in pursuit of revenge, wreaking havoc in both their own lives and societies.
God, how I wish they hadn't fucked this game's story with its convoluted structure.
