If you're looking for strength gains, then no, it won't replace a full body workout. For general muscle tone, then yes.
I really liked the workout (although it was slightly on the long side for me), but really hated the music (think elevator, WAY worse than Slim Series). The music was loud enough that you couldn't play your own. In order to drown out the music of the DVD, you drowned out Tari. Since you were often in a position where you couldn't see the screen, you needed to hear her cues.
I sold it. I don't think music has ever been a deal-breaker for me before or since. It's too bad, I hope she makes another version of it. I was nicely sore the day after.
