They are a lot of fun, but I don't think that 1,000 cals is accurate of *any* exercise for an hour. But they are a good workout with fun music and with the weighted gloves, even better!
I just got the original set that comes with 6 work outs and the weighted gloves. I am having tons of fun with them so far. They are a bit dancey which I normally don't like but it's not too much and I am finding it really fun so far! If you are interested in them, give a click on mine or Jess' link MDB linke below to get more info. There are lots of TJ's to choose from! HTH!
I agree with both of them. TJ is a great, fun workout if you want a change. I'm not a 'dancey' type girl either, but it's kind of fun to let loose with these workouts. Chalene is funny, too.
