I have the three DVD's you mentioned. I've previewed them all, but haven't done Kick Butt Bootcamp yet (It looks like a fun and challenging workout, though it annoyed me that the instructor of this section doesn't follow the beat of the music: I hate it when instructors use music with a heavy beat, and can't follow the beat!)
I've been using portions of the Abs and Legs workouts as add-ons to other workouts. The stability ball section of "All About Legs" gave me glute DOMS for 3 days! And I actually felt a "pump" in my glutes while doing the 1-legged squat portion.
I've done two segments of the "Abs" workout: the medicine ball segment (challenging, with some 'planks/push-ups with hands on the med ball" exercises that really challenge the core) and the stability ball segment (also good). The exercises are very core oriented, and nary a traditional ab exercise in the bunch.
I'd say Mindy is very athletic, somewhat hyper. She does have a goofy sense of humor, which is a bit toned down from her earlier workouts, but one thing that annoys me is that often when she says the word "ball" (as in stability ball or medicine ball) she has to crack wise or make some innuendo, which I find very much like "10-year-old-boy" humor.
I think there are supposed to be some clips of these workouts at
