I have the All Step workout, and about a month ago got Power Max, Rhythmic Step, and Step Heat. Haven't done All Step in while, but if I remember correctly it's fairly short. The three that I recently got push about an hour each and I really enjoy them...lots of sweat! I am new to Cathe so don't have a lot of her workouts (yet), but if you enjoy All Step and just want a longer workout, I would recommend any one of those 3.
