I have ONE of the jazzercise workouts, it's pretty dated (80's) but that really doesn't stop if from being a good workout, the moves are good but being from the 80's it's a lot of work!! (Remember that was the "No Pain, No Gain" era). BUT this workout is not that, it is very good but it's tougher than the new wave workouts like the standing ab workouts and such.
I don't know, kind of hard to explain I guess. It really is a good workout, the moves are not difficult but it is a dated workout. That's really the best way I can describe it. If you have any of the Jane Fonda's you'll understand what I mean. About an hour long, mostly isolated routines (first warm up, then arm work, then leg work, then push ups, then abs, etc. like that).
I don't feel like I'm being very clear but I tried
If you enjoy 80's dance moves then I think you will like the workout. But when it comes down to it it's more an 80's workout than an 80's dance workout (but again, that could just be the one I have and I only have one).
Good Luck!!
