Hi Lissette!
The tapes I use are the Walk Away the Pounds. I have the original set with the weighted balls (my favorite,the one I always go back to ) and also the Express set. I have the one for abs too but don't like it as much. The 4 mile walk is one she did around the time of the WATP Express. You can buy these on Amazon or Collagevideo.com.
I like them because I have joint and muscle issues and these are pretty low impact but you can work up a sweat. I took to setting up a program of ELO music on my computer that I use during the tapes-I like the music better and the tempo is perfect. I get tired of the same audio on the tapes after a while. I also find that doing them to music I really enjoy makes it more fun.
Hope the treadmill is fixable-did the motor go or did the belt just give out?
