Basically, a woman with the same amount of muscle mass as a man will be just as strong, BUT since women cannot develop the same muscle mass as men, they, generally speaking, are physically weaker than men.
Another thing is that people have to get it through their heads is that, regardless of what the constitution says, not everyone is created equally. Some people are smarter, some are shorter, some are more artistic, some can't lose weight easily while others can't gain weight no matter how much they eat.
Men and women are NOT the same, either. Period. Cry as much as you want; it won't make a difference.
The following examples are generally true:
Men are taller than women.
Women weigh less.
Men have 50% more total muscle mass.
Women have about 10% more body fat than men.
Women have less bone structure than men, but their pelvis is wider.
Men can pump more blood through the heart than women due to a 25% larger heart in men.
Women are more flexible.
The list goes on and on. And that's just the physical aspect of the differences. Then, you have the psychological, chemical, and other differences. The point is: We're different. Get over it.
