The average woman has much less upper-body strength than the average man. This is documented biological fact. This does not mean that there aren't physically-fit young women out there who can whip my gray haired butt. It means that a very physically fit young man is stronger.
Case in point, the US Olympic Women's Hockey Team. Some of the fittest women athletes in the world.
Did exhibition matches against high school boys teams and lost. Well, they won some, and lost some, but still, regular boys high school teams held their own against the most fit women in the world.
Now, how well is even an above-average woman going to do, in tasks that involve lugging 80 pounds of gear on her back, up and down mountains, for miles, and having to be in condition to fight at the end? How many women do you know who could lift a 200 pound man and carry him to safety? Political correctness will get people killed.
We've all seen pictures of women's bodybuilding champions and some are much more well muscled than most men.
When I was 23 I backpacked Isle Royale, Michigan out on Lake Superior with my clam girlfriend who'd backpacked the island before whereas I hadn't.
My pack weighed 77 lbs, compared to my 145lbs. while hers weighed 37 lbs compared to her 100 lbs and had all of the food so hers got lighter by the day, 11 days total.
I thought I'd never make it just 50' down the trail, my feet were already bloodied from trying to break in my new Italian hiking boots in the weeks before.
Fortunately I'd brought a pair of nylon joggers which I had to switch to fairly soon as it was 45 miles as the crow flies but with extensive climbs up and down and switchbacks, the actual miles was nearly double that.
We made it to the end and I lost 15 lbs while my feet tore through the nylon joggers during the many descents where my toes would get pushed, tearing through the fronts of my joggers but by then and using lots of moleskin I was able to finish while wearing the Italian hiking boots.
After the half way mark I was able to do wind sprints with the 77lb pack on my back as my body had adjusted to the workload while my pack had become heavier from the all interesting drift wood and moose antlers I picked up along the way.
I did notice that her womanly build, wider in the hips with more proportionate strength in her legs, made her very adept at dealing with the rigors of the hike.
My greater arm strength was mostly a non factor as once I had the pack up and on it was all supported by my spindly legs and narrow waist, or in those days it was.
Women can deal with a lot and many men are very surprised at the extent that is the case.
Not to mention their innate ability to handle pain, probably as a result of being built through evolution to handle childbirth and carrying the children around.
