Nonsense of course. The woman’s body is shaped differently, so the legs are father apart, and in later pregnancy, all the ligaments stretch a bit so falling and getting strains and sprains is more common.
That’s why we docs usually get our women off of heavy work after 20-28 weeks: falls are more common, fatigue is more common, and if you hit the uterus wrong, you could end up miscarrying.
Isn’t there a huge difference between a woman slowly adding on 25 pounds of baby during her 9 month pregnancy as she and her body adapts and adjusts, and some guy jumping up and suddenly strapping on a 25 pound fake apparatus and finding out it affects him?
To me it seems like they are not very similar at all.
