I really enjoyed this dvd. I was looking for something more fun than your average workout video and I found it. I read the reviews and decided to give it a try. I did it for the first time yesterday and had a lot of fun and worked out pretty hard! The girls are great hosts, you can tell they're having fun too and they aren't constantly shouting out at you but they do have words of encouragement. They laugh and make a few mistakes (like saying right when they mean left) but they correct themselves and it's fine. The main reasons I only gave this 4 stars are the low production values (not that it affects the workout at all) and the fact that you only learn one routine (although from the clips they show I don't know that I could do all the great moves they do!). Other than that it's a great find and a great buy and anyone looking for a fun way to get your heart going should definately check it out.
