I totally feel you on how hard it is! I did the first level for 10 days straight and then moved on to the second level. I thought I was going to die too when I was doing it every single day.

Jillian said recently in one of her radio shows she doesn't expect people to do it every single day but to do it along wit other fitness DVD's or cardio.

I have been doing level 2 for a few weeks now and am going to move to the third level soon. It does get easier the more you do it though. My body is changing very quickly though so as hard as it is I know it is worth it.

Keep at it! It gets easier!!
