Hah, are you serious?
I lifted heavily for 4 years, and I can unequivocally say that men are by far much stronger.
Comparing the average man to the average woman, it isn't an issue of men being 1.5 times stronger, or 2 times stronger.
The real disparity is about 4 to 1.
In all of my lifting experience, very few times did I come across a female who could bench more than just the bar, maybe 5 pounds on each side. (Keep in mind this is sets of 10 reps)
