Self Magazine has been putting out exercise dvds for a little while now and each that I've seen, are really good. This is another good workout that gets your heart-rate up and burns heaps of calories.Kimberly Spreen is the instructor (home exercisers will know her work - she's excellent) and is motivating and energetic. It's dancey and easy to follow along and not too hard to get the moves down. There are latin style moves like mambos and cha chas and regular cardio moves like jumps, kicks and jogs. She always stresses that it's more important to have fun rather than try to be absolutely perfect and try too hard. It's nice to have it filmed outdoors because seeing the sunshine is motivating when Summer is around the corner, or you are in the midst of a gloomy Winter.This is a fun workout that is probably best for beginners or more intermediate people rather than if you are advanced - you'd be bored. I like this one and really recommend it if you want a fun workout that you can do in around 50 minutes.
