To clarify:
Are there women who run in that dumpy way the one on the left does in real life?
Yes, of course.
Are those real life women elite gladiators, pro athletes, or in any way physically fit?
NO. They're middle school girls in P.E. who are being forced to try to figure out how to move themselves for the first time in their life.
So WHY are we having the bodies of elite athletes, without the obvious technique of elite athletes? It's absurd and to the outside perspective it just looks like you're trying to make tantalizing women.
Oh but I know, "this is the hero form" right? That is a non-answer.
No hero would run like they just want class to be over so they can text that bitch Katie about how they really feel about her last Facebook post.
