laughing ourselves skinny

I know it sounds like the beginning of a joke: Four friends walk into a gym together.....
but it's no joke. We're having a blast together, three friends and I. We are managing to do gradually increasing amounts of cardio followed by at least an hour of strength training.
Usually we go at night, after those of us who have kids with a bedtime get the little monsters settled down.
We are amazed, in all honesty, how much fun it is to have a big "girl party" that doesn't involve male strippers or alcoholic drinks! Although we do muse about such things. We laugh nearly non-stop and often involve (disturb?) others around us.
It is fun to watch the faces of the poor women who venture into the Ladies Only room, unsuspecting creatures that they are. One, a black woman with gorgeous dark chocolate, velvety-soft looking skin, beautifully coiffed hair, lipstick, and the perfect figure, was going at a fairly good clip on the treadmill when all of a sudden she disappeared. Doubled over with laughter at our shenanigans she was.... good thing she was holding on!
Ennyhoo, we have named our journey "Laughing Ourselves Skinny". Look for us on the Comedy Club circuit.
