HI- I saw this thread and wanted to pop in to say I am also sooo addicted to the Firm. I am constantly on ebay finding new tapes to buy. I like some of the older ones better, but they are all great. I always sweat a lot and have seen some amazing results! I do sometimes get confused with the steps- I got an older one called fat blaster that has great cues and I don't get lost easily. Sometimes even on the ones I have done a lot I am looking at the screen like-what are you doing? I also had a hard time with the salsa sequence in Cardio scuplt for a long time- and if my exercise partner and I start talking at that part we are both lost!!
