I have used Leslie Sansone in-home walking videos for the past two years with good results, lost 40 pounds so far. In my area, they can be rented from video stores or purchased at big box stores or online. She also has some free workouts on Youtube. I was skeptical at first, but being able to walk 1 to 5 miles in my living room when the snow is flying outside is great. Leslie is very encouraging, some people love that, and some don't, but it works for me.
