Query: it's okay

I just used this tape the other day. The instructor does a good job of explaining things, and they do spell out what you are doing very well. The only thing I didn't get out of it was a good workout. This would be fine if you are a beginner or are new to exercise, because it is helpful, but if you are used to working up a good sweat or feeling like you've really gotten a good workout, I didn't get that from this tape. So I would recommend for beginners, but not for someone who's done this for awhile.
