Query: Great for all levels

This is a great DVD for a few reasons:It is broken up into 10 minute segments, targeting different body parts, so you can do as much or as little as you please.Each 10 minute segment gives a great workout for that body part.It can be modified easily if you're just starting out. It's also great if you're sick of doing crunches and squats. I like the instructors; they set a good pace and explain the movements and the modifications. Each 10 minutes is challenging but not overwhelmingly so.
