Query: good workout, not a dance lesson

This is a good dance-y workout, but you won't be using any of these steps on a dance floor these days! Very fast-paced (you can either stop and rewind to learn the steps, or just pick them up over a few days, as I did) and a lot of fun -- high energy, cheery, not annoying. You really will see results if you stick with it. If you do it on carpet, just be careful with the twists, use strength so you don't twist your knee instead of your whole body, and know your limits.
