Hi I love Mindy's new kickbutt bootcamp!!! It really makes me sweat buckets!! I don't know about the Amy B workout, you could do a search I know several people have posted about it. The cIA criss cross cardio is a good kickboxing workout but not as intense as Mindy's. CIA's All body CArdio is great, I found it very intense, just did this , this morning . (it's on the double cardio dvd which just came out)
