Query: Kari Anderson - top class instructor!

I bought this ab DVD a few years back for myself and have to say that I've never been disappointed with any of Kari Anderson's workout DVDs. I always get the full benefits of whatever she teaches. My daughter then asked me to purchase another for her to use while at college, as she's also familiar with the ab workout from using my DVD at home, so that just goes to show how we both enjoy it and like the results we have gotten from doing it.Great ab workout all round!
