Bodies like to move. I know some folks are rolling their eyes right now because they firmly believe that they could lie on the couch until they became one with the upholstery, but hey, rolling eyes is movement, so they just proved my point.
Silliness aside (who am I kidding? I can’t leave the silliness out!), all of our bodies do, in fact, like to move. The question is how much. When we go too long without moving, we feel stiff and sore. Our joints refuse to open or close as much as they used to. We forget how to get enough air into our lungs to support dancing or running or even walking.
The good news is that bodies also remember. When we give our legs a stretch or our neck a little roll, our bodies remember how to do it and reward us by making us feel better. This is true even for those of us who have arthritis; studies recommend taking even arthritic joints through their range of motion each day so that there is no further loss and maybe even a bit of gain. Starting slow with a few stretches or a short walk helps.
Go play.
