This was recommended to me as a great workout for beginners, but I was totally lost in the first 60 seconds of the warmup! She keeps adding steps without a whole lot of explanation and making it look easy, which seems a bit baffling considering that she's talking to a bunch of people who think they are "dummies" at fitness!The ab exercises were WAY too hard! I couldn't even make it halfway through that section. She does give "basic" modifications for some exercises, but even the basics were too hard for me.To be fair, I think this program is probably pretty good--and I will keep working on it as I progress in my weight loss program--but if you are are a true sedentary beginner and looking for something to get you started, you might want to try something else first.
