Have you ever used Turbo Jam?

It’s the middle of the night and I’m watching Turbo Jam. It looks great. Looks like fun, most of all, and it looks like a low impact workout. But I wonder if it really is as effective as they make it sound.

Have you used Turbo Jam? What was your experience? What were your results?

Also, do you think a pregnant woman could do the workout(s)? I’m seeing some of these “ab moves” and I think some should be avoided, but there are other moves and the workout as a whole seems doable.
