My suggestion is to have both upper-lower body work, introducing new step moves ala "Rythmic Step"??, also I feel the workout should last for 60 minutes not 50, another important factor for me and many others is the music, fun, loud and upbeat,that should do it. :0)
It goes without saying PLEASE make it tough!
