Hi Carol,
I have been doing the 1 mile get up and get started, and just advanced to the 2 mile high calorie burn. I also have the 3 mile super fat burning and the 4 mile super challenge dvds, and I believe they go along with the 1 and 2 mile workouts. I have looked through them, but I've not worked my way up to them yet, but they do remind me of the same workouts, just longer. I don't think Walmart sells both of these, and I haven't even looked at Best Buy, but I did buy both of mine from Amazon.com and if your total is $25 or more, you get free shipping, and they do have very fast service. Hope this will help you some.
