I ordered The Bootylicious Gliding One and All Systems Go, as well as All About ARms. I really like All About Legs. I also have Gliding Gone Wild and it's surprisingly fun. I like it but I use it days when I want my cardio to be a little less intense with more focus on working the legs. I love Gliding for working the legs. It really gets them differently than traditional exercises. The only thing I seem to get a bit sore from these days is Gliding. If you really press into the floor -- it works even better.
