It's quite stunning, often literally. The strength of a male, past puberty, is phenomenal. Even small, weedy men.
Yup. I haven't been hit, but I HAVE been blocked from leaving a house - me and average woman, him a very average man, not a gym-goer or anything. It was a narrow corridor to the exit, he was stood in it, and I couldn't get past no matter how much I tried. I tried to push and pull him out of the way and he barely moved. Then when he got sick of that, he grabbed my arms and pinned me against the wall. I might as well have been in shackles, he felt that impossible to get away from. It really is something you have to experience to believe. Again, I'm not especially weak, and he wasn't especially strong - just both average in height and weight.
In TV and film, I've heard it described (maybe on TV Tropes) as waif fu - five-foot-nothing Buffy beating the crap out of huge men being a prime example, and River Song in Firefly another. I love both those programmes, and even though it's explained in-universe - Buffy has super-strength and River has been enhanced somehow - there remains the fact that what we see is tiny women obliterating men with fists and feet.
Actually, there's that season 3 episode of Buffy where Giles gives her the potion that depowers her to the level of a normal girl, and she's shown as shocked and frightened by how vulnerable this makes her. Good episode.
