This was the first of the new firms that I have tried. I love it. It is fun and full of cardio with light weight training. I especially loved the kickboxing segment and the music. I have now tried several of the new firms and this still holds at the top as one of my favorites. I like Allison as an instructor and think she does an excellent job in this workout. I am a Firmie and have the other step systems and while I think those are probably a little better of a workout due to the step; it is a nice change in my routine to not use the steps everyday. I hope you all like this workout as much as I do!
