content: I got cocky and started with Level 2. Big Mistake. You can't really follow through since she goes by the moves quickly (some of the moves were new to me).I ended up getting irritated half way through the workout and wasted a workout day.So - Read the Recommendation and Do level 1 first!A note about her 'twitter' comment - I understand that she wants to get the message out to people that if the workout was too easy, they probably need to increase the resistance. But it could have been phrased in a different way. I don't care personally - after all she is human. But it does distract you from the workout for just a sec.Word of warning - It is Hard on the knees! If you have a knee injury of any kind, be very very careful. The workout is hard and does what it promises, and thats why it gets 5 stars.
