Query: Great workout!

This is a great 30-minute workout. It's simple yet rigourous enough to make you work up a sweat - even for more seasoned exercisers. Sometimes, I felt a little clumsy with looping the bands around my shoes and had to slow the DVD down to see exactly what she was doing. I am getting the hang of it though. Overall, this is a great workout for the entire body.
