I've seen a " fix" on skyrimnexus, but all it does I believe is make ALL the " butch" animations be "weak" wether or not you're actually butch or not yourself, which I think is unconvinient if you have more than one character, like me where one can be very strong and the other not so strong.
It's also very noticable on companions, especially female companions like Lydia and Mjoll. They stretch their arms out pretending they're male bodybuilders when they're really not.
