Edie,
What are the reasons for your interest in Callenetics? I don't want to advise you to buy it unless you know why you want to use it. Other posters on here have given their comments and, as they say, it is very slow, lots of little pulses workout. You will need a ballet bar or something high for leg stretches.
I checked out the link you sent me and I am not sure about the DVD as I don't think that I used that one. The one I used was a one hour program. I heard the Super Callenetics is for advanced exercisers. People say always start at the beginning, but I don't think it is that difficult to jump right in at the advanced level.
I must admit that I never saw the results they promised in the workout, but that was because I was not doing cardio exercises to lose the fat. It gave me good flexibility in my legs and even today I can do the splits quite easily.
