At my gym we spar every Friday. One of the participants is a young lady @24, rather stocky of build and not a weakling. She is a parole officer and she trains in kickboxing and sometimes jiu jitsu against the eventuality that she should be attacked while conducting home visits with her sex offender clients. A month or so ago she was sparring with a skinny 16 y.o. kid who was taking it too easy on her. The guys told the kid that he had to go harder if she was to learn anything. So he kinda shrugged his shoulders and said "Ok". A few minutes later she had a bloody nose and was crying.
You must have a heart of stone to not laugh at that.
Note that the damage was done by a skinny teenager. An average guy has roughly double the upper body strength of a woman. What's truly astonishing is how that strength can be very quickly doubled by spending some time in a gym.
Women are delusional if they think that they can fight a man.
