I'm looking to branch out beyond Leslie Sansone. Is there anyone you really like?
I'm looking for aerobics - not something like the 30-day shred. I also need low impact (back and knee issues) or something that can easily be adapted to be low impact - so tons of jumping jacks and the like are out. So, what do you like?
I can't recommend a specific video, but I have bought from collage video. They have a great selection, and I like that they have clips of the videos so you can see/hear it before buying.
