I workout several hours a week and I teach a fitness class five days a week. I enjoyed this workout and I got a good sweat out of it. This is a challenging workout. The title and some of the language used by the instructor make it sound like it is aimed for a beginner.The workout is broken down into several sections, and the user can break it down and sequence it to match available time and choice of body parts.The exercises are demonstrated quickly, and only shown at one level. Modifications and accommodations are not shown or explained. Many moves involve jumping up and down or side to side. Weights are used, but the instructor does not discuss how to use them safely. The transitions between exercises are quick.If you are experienced at working out, this is a good DVD. It's good to have for those times when you cannot get to the health club. If you are not already in good condition, do not get this DVD. This is not a beginner workout.
