There is one DVD that gives you instructions on all of the different moves. You practice each move on that DVD. There is another DVD called "Cardio Party" that gives some minimal cueing and "instructing". She will say something like "Remember we reviewed this....it is side, together, side", for example. There is absolutely no cueing at all on the "Zumba Live" DVD.
Cardio Party and Zumba Live are both around 50 minutes, I believe. The Twenty Minute workout is a nice add on to make a longer cardio or for a warmup before weight work.
I do not like the "Toning" one at all! You use the "shakers" that weight around 1/2 lb. I didn't feel anything at all out of that workout. If a person used 3-5lb weights, you may get something out of it. It was kind of an AWT workout...except those "shakers" were worthless, IMO.
I have not done the "Abs" yet. I honestly don't think I have even previewed it
The classes I have been to are a lot of fun and intense. The first time I did Cardio Party, I was able to get my heartrate up pretty well. I would rate them as "intermediate".
They are really close to the classes (at least the ones that I have been to). I think the live classes are a lot more intense because I tend to put more into it and there is more of a fun factor because of the people. The music on the DVDs are exactly what was played in my live classes (a plus IMO!)
I really think they are worth the money if you want some fun cardio that is basically low impact and not killer. I wanted them so that I could learn the moves and practice them for class. I didn't expect them to be as good as they are. I was pleasantly surprised. I usually run and do Cathe for my cardio, but these will definitely have their place in my rotation. You can make them more intense....or less intense.
