I like both series alot. If you increase the weights used, the metabolic & weight workouts can be as advanced as Cathe's advanced workouts, I think. I think the cardio in LITE is less intense than ICE, probably because LITE is lower impact, but I use light hand wrights and that boosts the cardio factor. They both are fun, have good music, sets, etc. So, I'm no help ...either is good!
