Good clear instruction and again, Jillian is not annoying, even giving a 'we're almost done" speech right when you need it. It's a great workout, making me sweat and runs in a great amount of time (30 minutes). It would help if you have taken a yoga class previously.
I do wish it had a slightly extended warmup and more relaxation at the end, but hey, it's yoga meltdown!
I suggest watching it first, as the beginner modifying poses are not always shown or explained until near the middle/end of the pose.
If you have back problems, this video should be approached with caution, as it has a lot of back extensions and the camel pose= backbend.
