My husband teaches a couple classes a week at a local gym, and every now and then they clear out some equipment, so the other day he came home with a BOSU. If you don't already know, it is basically half an exercise ball attached to a platform with hand holds on the side. You can use it dome side up or dome side down.

I've been playing around with it for the past few days looking for ways to incorporate it into my workouts. I've done push ups, planks, reverse crunches, and squats so far. Anyone else out there using a BOSU? What exercises do you like best?
