In the past, I've only done CS or Essentrics with other forms of exercise (walking, Ellen Barrett or kettlebells.) Mostly, I would do one or two Seasonal episodes as a warm up or cool down to something else.
It's very much a stretching/toning workout that works to lengthen and strengthen the muscles. I don't find much cardio element to it, so think it's best to use in conjunction with something else (if you have weightloss as a goal.)
Like anything else, the more you do, the better you get at it, and you can really give it your all! If you can string a couple episodes together, I think that's best. Or, get a couple of the longer full body essentrics DVDs in a few times a week.
I am really enjoying Season 8 right now! Miranda is the best she's ever been, I think. Very focused and she works you out good! She's really wonderful. I have yet to try Sahra's new Essentrics, though I have them waiting for me.
