I may be biased because I am a fan of Jillian since the 30 Day Shred came out and I have all of her DVDs, but I got to say, she does not disappoint on this one. I consider myself advanced and I felt the burn on Level 1. Like she said, if it is too easy, just add weights and problem solved. But even without weights, it burns.
The only thing I noticed that was inconsistent is it says the workouts are 30 minutes long, but they are actually between 40-45 minutes long (Level 1 about 40min, Level 2 about 42min and Level 3 about 45min). I guess if you don't count the warm-up and cool-down, then they are 30min of strict strength/cardio training.
And for those people that get annoyed and actually pay attention to what she is saying, she complains a lot about people saying on Facebook and Twitter that her workouts are too easy and how that pisses her off and she mentions that a few times. Not a big deal, but I know people get annoyed about stuff like that.
If you own her other DVDs, you will notice she incorporates a lot of the moves from 30Day Shred and Ripped in 30, especially on the Level 3 workout. That being said, it doesn't feel like you are doing the same workout as in the other DVDs. I like that these workouts focus on the lower body because I am sure they burn a lot more calories.
