I just did Imax 3 last night, it was great. I feel so accomplished after doing this one. I love Imax 2 as well and Cardio & Weights that comes with it is super fun. I've been doing it on 8" platform and it is a blast. Imax 1 is good too, I just don't use the more dated workouts very much, that's just me though. I don't care for Rythmic Step either but I absolutely love almost all of her other workouts. It's all up to personal preference.
