The beauty of push ups is the following...
They work your back muscles.
And the triceps in your arms.
They cost you nothing to do because they require no equipment.
You can do as many or as little as you want.
You can try different kinds of push ups (like finger tip push ups, or hand stand push ups against a wall, etc).
They are also good for the pecs and thus count as bust firming exercises which make your breasts more perky and younger looking. Bonus!
All you need is a clear space to exercise. You can do it barefoot or even naked in the privacy of your bedroom.
Push ups rock!

I find it strange that so many women (including black women) are adverse to exercising. What? You think you are going to look like a female bodybuilder just because you did a few push ups? Nonsense! Complete hokum!
I call it our feminist duty to stay fit so if the need ever arises we are in shape and able to meet the challenge.
