This high/low workout is sort of like intervals. You do regular aerobics for a couple of minutes, and then you do high-intensity for a minute or so. You can definitely tell the difference in intensity, but I'm not sure that you get up to maximum or over during the intervals. Nevertheless, it's a great workout, and fun too.

Choreography and intensity (during the "regular" phases) are both intermediate. Tracy doesn't waste time explaining the moves, so the first time you might have a little trouble following her. But none of the moves are very complicated, so you won't be lost for long.

The workout flies by. The aerobics section is 20 minutes, but it seems even faster because you're switching back-and-forth with the intervals so often. I don't think this is quite as good as the NAC Interval tape, but it definitely has its merits. And at under $10, who can resist? (I was lucky, though, I got mine through the exchange!)

I give this workout an A-. If it were just a little bit longer, it would get an A.
