It's basically 3 parts:
1. approx. 37 min of step - a fun routine but faster paced than her other workouts. Nice and intense.
2. 5 power step circuits made up of a mini-routine, into a mini-blast, into lower body endurance training with dumbells and a barbell - very intense at this point.
3. Upper body endurance style lifting - moves quickly but gets pretty much everything done!
I usually do the first 2 parts for a good solid hour workout - I love doing it this way. I tend not to do upper body work after cardio unless it's a circuit workout that includes upper body.
Go for it!
