Hi !
I have a variety of tapes that I enjoy. I use Leslie Sansone's, Tae Bo, Kathy Smith, and Slim In 6. I usually do a program for a while and then switch around so that I don't get bored and my body doesn't get used to the same exercise. A good place to look is collagevideo.com. Not only do they have a great selection but you can preview some of the videos before you buy. Good luck in whatever you choose to do.
