I love this video, have been doing it a couple of times a week for about 2 years, and still haven't gotten tired of it!
The "low impact" is important to me (not allowed to jump around or do Step), yet I still get a good cardio workout in the 25 or so minutes, which is a great length, too, as I never seem to have enough time to do the 45+ minute ones. I find the background music enjoyable - the melody doesn't distract, yet the beat and tone change with the various components of the routine. I also find that with outdoor settings, I tend to look at the scenery, but the studio setting helps keep me focused on getting the most out of my workout.
I think this is a great video for beginners because the routines are not complicated, and you can work up more intensity with bigger, more exaggerated arm and leg movements, and emphasizing more resistance during the motions.
The biggest surprise is that that girl pictured on the jacket is not in the video!
