as far as intensity and bb series i don't have those for the premixes but i really love the premixes on core max. its like getting another 3 workouts b/c no matter which one i do it never feels like the same workout. i havent done all the premixes on kick max but i like those b/c it can go by length of workout to how hard i want to work it. i am so wanting bb on dvd for the premixes especially forlegs and glutes.
