This workout is seriously killer! Those "high knees" had me begging for mercy! And there are lots and lots of them - unfortunately, this can get quite repetitive (and exhausting!). But boy, does it jack your heart rate up! I was interval training throughout! Now that I know there are so many "high knees", I'll have to decrease my range of motion on these so I don't run out of steam early. I think this would be a good cross-training tape for intensity-lovers (there is no choreography to speak of, really), and I recommend it for that purpose.

Instructor Comments:
In this video, I actually wished she had talked more - the conversation helps keep me from noticing how hard I'm working!
