One of the requirements for being in the US military is that every once in a while, you have to pass a physical fitness test. The standards on these tests are lower for women than they are for men.
In the army a male soldier, age 17-21, has two minutes to do a minimum of 42 pushups. A female age 17-21 must do 19. A male soldier age 17-21 must be able to run two miles in 15:54. A female, age 17-21 must do it in 18:54. Sit-ups are equal.
I knew strong female soldiers who could pass the test by the male standards, but there were also many who could only pass because of the double standard. It should all be equal.
Before you ask "How is it relevant?", I'll say it's VERY relevant. Anyone eho has served in the military can tell you, that regardless of your job, you do a lot of heavy lifting.
Also, these double standards do not exist in combat, and if you are not strong enough to do 25 pushups, you are NOT going to be strong enough to pick up a 230 lb soldier and carry them to safety.
