Switch out your sedentary seat for one of these sweet-looking ErgoErgo Seats ($100). Not only will it look like you're sitting on a big, modern accordion, it'll engage a ton of extra muscles your regular chair doesn't. Think of it like an improved yoga ball. It won't roll out from under you, but you'll still reap the benefits of improved core muscle strength and balance. The price tag is decent, too!
