Query: I loved this tape...

This was one of my favorite workout videos. I think it was supposed to be a dance club-inspired workout because the sets are dark, there are sillouettes of (tasteful) go-go dancers in the background and it even came with an accompanying tape of the music they used in the workout. I liked Petra's choreography and didn't have trouble following along too much after the first time through, and I've never had dance training. This workout is about 30 minutes long.
