I bought myself a blue exercise ball years ago, fully intending to take up Pilates and stop shelling out excessive amounts of money on gym membership fees. The ball itself cost only $40 and came with a Pilates DVD, plus there are all sorts of Pilates demonstration videos on the Internet. I thought this was perfect.
My exercise ball has since served two purposes: to gather dust, and to seat the occasional guest to my apartment when I run out of actual chairs. My gym membership has been cancelled, but only so that I can become a desk chair potato, one who spends her time doing homework and such, but gets nowhere near enough exercise.
So how's this for a post-birthday resolution: I will make sure that the exercise ball is not a waste of money. I will push aside the living room furniture so that I have enough space to do Pilates, or exercise ball sit-ups, or whatever the latest exercise ball fad happens to be.
Just as soon as I figure out where I've stowed all my gym gear.
