, Okay, it's really simple to do, but difficult to explain:
Take a simple kitchen chair, as light weight as you want and place it, seat out, against a wall. Step up to it, facing the wall and lean over and rest the top of your head against the wall. Now, reach down and pick up the chair with both hands and try to stand upright while lifting the chair without stepping back or moving your feet.
The concept is that women have a lower center of gravity than men. They (I should say, any normally shaped woman, not some of those you see shopping at Wally World) will have no problem lifting the chair and standing up. Men's upper body weight prevents them from doing it.
Okay, there'll be some exceptions and do to the fact that I first heard about this and saw it demonstrated when I was in junior high, now called 'middle school', things, especially the average weight of Americans, have changed. This trick might not work as it did before over fifty percent of the population was obese.
