Query: This is a really great workout video

This is a really great workout video. I like how they show modifications to some of the workouts on the dvd, which makes this dvd really great. It makes it easy for everyone to workout. I also like how there are three different levels of difficulty in it. All in all, this is a great workout video. I would recommend it to anyone who is trying to lose weight.
