This workout is one of my favorites.
I tend to get bored easily and circuit training is a good way to stay motivated and enjoy the workout .
I really like the step aerobic in this video because it's not too basic that it's get boring, and not too complex that you have to focus too much on learning the steps and can't enjoy the workout.
I also like the fact that it's not too high impact. Althogh I'm only 20 years old , too much high impact is never good for the body. I will never understand how people exercise regurly with Cathe's cardio workouts and don't have problems with their knees.

It's contains 3 cardio segments on the step that become shorter but more difficult and complex ,every time you get to the next segment. the totel cardio time here is 23 minutes.

The strenght workout is also fun and it's contain some effective exercises but there are'nt enough sets. it's not the kind of video that can really shape your muscles, especially for people who exercise regurly with Cathe or The Firm,it's more a workout that can maintain the muscles or add muscles to people that just begun using weights.
the workout here is exellent and very balanced,but ,if you really want to shape up, you need more time ( to do more sets)
in the end you have 6 minutes of tough ab segment and some good exercises for the hamstrings ad glutes the uses the step.there are'nt any planks or stability ball and it's only 6 minutes, but you still can feel the abs burning. of course that someone who wants to focus mainly on abs will be better of with video that spent at least 15 minutes on abs, but for a total body workout, the ab segment is great, especially compered to most FIRM workouts that tend to neglect this area.

the only thing I don't like about this video is that the set is kind of boring. I like videos that you can get amazed only from watching the beautyful background.like The Firm for example.

all in all it's a great workout when I want too burn calorise , work the entire body and also enjoy myself.
I don't understand why a lot of people (reading the reviews) didn't like it. I wish that karen puts new video with similar intensity and complexion of the step portition and add some great ab workout in the and.
