Hi, Mary,
I don't have this particular workout, but I have Michael Olajide's KILLER ABS AND BACK, so I can at least tell you about that...To tell you the truth, I haven't done that workout for such a loooooong time because I really, really have to psyche myself out to do it since it's so tough. But when I DO do it (lol) I always end feeling "powerful" and think I should put it into my rotations more often.
Hmm. Come to think of it, maybe I should whip it out again! :7
Anyway, I like the workout and the instructor - he's really inspirational to watch - he has an incredible body and moves so fluidly he's fun even just to watch. But again, at least this particular workout I have is tough and I don't remember it having a huge "fun" factor.
Sorry I can't tell you anything about the Aero workout you were looking at, but I can say that I've heard some good things about it.
