Why Gadot's physique is actually nearly perfect for WW
Ok so before you bash me, hear me out for a minute. Wonder Woman is supposed to be around 5'11" to 6' tall, around 130 to 135 pounds in weight. Now consider that your average fit 5'7" woman is between 120 to 130 lbs, which can easily go up to 140 lbs. if you add on more muscle - then you'll realize that to be 6 feet tall and only 135 lbs. you'd need to have a very slim, lanky body even for a woman. Especially if the woman has as much muscle as Wonder Woman supposedly has, then that means for her to still be only 135 lbs. she'd need to have a very narrow bone structure and her musculature very wiry instead of bulky. She'd be built more like a whip than a muscular porn star.
Gal Gadot is listed as 5'10 in height and 128 lbs. in weight. That means she's only 1-2 inches short of comic Wonder Woman and only 2-7 lbs. lighter. And while I do agree that she could use more muscle definition, I'd say she really doesn't need any more mass. Her figure is very close to what Wonder Woman's should be, at least if we use WW's stats and not just base it on various (and sometimes very different) drawings of her.
Now compare that to someone like Henry Cavill, who's about 3 inches short of an ideal Superman and about 30 pounds lighter. I am not harping on Cavill by any means, as I was completely blown away by the transformation he made for Superman. I'm just trying to point out how silly it is to keeping bashing Gadot for her physique and in the same voice praise Cavill for his Superman physique when Gadot actually matches WW better than Cavill does Superman.
