I read the good reviews on this website about the NAC Interval Challenge and decided to try it for myself. I had already worked out to another interval training fitness tape (Kathy Smith's Functionally Fit Peak Fat Burning) which helped me get over a plateau when I was trying to loose weight so I know about the great benefits of interval training. This video is an excellent choice if you want a good interval training workout.
The video features five instructors who are National Aerobic Champions and each one leads an interval for two minutes of very intense training. The moves are more athletic than dance and they are not too complex so it is easy to follow the instructors. Two of the instructors on the video demonstrate a lower impact version of the workout that beginers can follow. I agree with some of the other critics that this video would be even better if it was longer but I think you can still get a good workout from this video.

Instructor Comments:
I found the instructors very upbeat, easy to follow and understand. They also seemed very knowledgeble about fitness.
