I have this set and really like it. The 3 mile with the weights is a good workout. I also have the express 4 mile, but they don't use the weights. I think the weights really help with the intestity.
I don't think I have seen this set in DVD. I would definately buy it if they did. Sometimes I do the 1 or 2 mile in the morning if I need a shorter workout.
Hope this helps. I really like it, and I love using the weights with it. I tried to use 3lb dumbells with the 4 mile once and my knees hurt for days afterwards. I think that is what did it. These blue weights don't hurt. They are lighter than the 3 pound dumbells.
