Insanity Max Cardio Conditioning

I started month 2 of Insanity yesterday and tomorrow am scheduled to do max cardio conditioning. How long is it? It shows it together with cardio abs to be 65 minutes, but tomorrow I dont do the ab workout. I was terrified of starting month 2, but so far do not feel too bad. My knees are hurting some. I feel a lot like I did at the beginning of month 1, just trying to figure out the moves! They seem a little more intense and the times are definitly longer. I look forward to the second time around with each workout to feel like I know a little better what to do and can really push myself! I love having to heart rate monitor to try each time to do more than the last so next time through will hopefully be an improvement!
