Kick Butt Workout!

So, I finally bought myself one of those exercise balls today. I also got a video to go with it. I figured the stretching might make my back feel better. WRONG! That video is only 10 minutes long and it KICKED MY ASS! I am sore in so many places. But I guess that is a good sign that it will actually work! So, to anybody looking for a good ab workout, I recommend you get yourself an exercise ball. But be prepared, it takes some good balance... I almost busted my tail a couple of times. I'm sure it will get a little easier with some practice.
