Women do have less upper body strength, less grip strength and less neck strength than men. This is a fact and I’m not denying that. However, women have the biological advantage in endurance and muscle stamina.
These studies show that women are built for endurance and outperform men in ultramarathons:

“Women are shown to be less susceptible to fatigue, which means that when they are doing strength exercises, they can go on for longer than men. And the difference isn’t trivial;
in research studies, women keep performing, rep after rep, for 60% longer than men doing the same resistance exercise. Better still, in the second half of the menstrual cycle, when progesterone is high, this effect is amplified.” - The Female Body Bible by Dr. Emma Ross, Dr. Bella Smith and Baz Moffat, page 160
“Certain characteristics of women’s physiology may also provide an advantage in marathon swimming. Women tend to have a higher body fat composition in comparison to men, something that’s considered a disadvantage in most other sports. But in swimming, higher body fat percentage translates to added buoyancy, meaning athletes don’t have to work as hard to stay afloat.
Over an eighty-seven-year period, the fastest woman to ever cross the Catalina Channel in California bested the fastest man by twenty-two minutes.
When it comes to swimming a lap around the island of Manhattan, the top ten women were 12 to 14 percent quicker than the top ten men based on thirty years of finishing times.”
