well that's most probably a truism, but is very difficult to verify with actual data, trained athletes, in this case swimmers, women have about 60% of the strength of their Male counter parts, with the general population is a lot more difficult to come up with a hard and fast figure,
men, most men have the capacity to be stronger, but if they dont train and the woman is sporty or works in an industry that has lifting r strength involved then the advantage may be very small or non existent.
8ve met some unfeasibly strong women in my time, girly girls that could seriously embaress a lot males. when I was a teenager, I ended up in a pushing match with my younger sister, she more than held her own as she had spent 6 months messing about with her boy friends bullworker. I immediately purchased a bull worker, no one wants to be beaten up by their little sister
but the same general strength rule applies, the stronger you are, the lower the % of people who are substantially stronger than you
