I have done Sylvia's Walk at Home workouts 3 times now and let me just say they kick my hiney!!!! They are hard. I really like them because the steps are not complicated, so we can talk and goof off and still do the workout. Sylvia lent me one of the DVDs and I did a "2 mile workout" today. It was hard and fun. The kids kept getting in the way. But I only knocked Jared down twice and stepped on his hand once. That's pretty good right?
